The described embodiments relate generally to retail packaging. More particularly, the present embodiments relate to a removable tear strip, a system that provides support to a product having movable components, and a protective film. The packaging may be made of paper or other recyclable materials.
Product packaging is an integral part of a customer's experience. It introduces the customer to a product, and can affect the customer's feelings toward the product and the company that created it. Packaging that is simple, clean, and secure may help influence the customer's impression of the product packaged within.
Structural and environmental considerations may also play a role in designing packaging. For example, packaging may be designed to be environmentally friendly—while retaining sufficient structure to ensure robust protection for the products contained within it.
Packaging described herein achieves these and other beneficial characteristics by balancing structural robustness, eco-friendly materials, and aesthetic elements.
Some embodiments disclosed herein are directed to packaging including a first collar portion configured to conform to a periphery of a first product portion, and a second collar portion configured to conform to a periphery of a second product portion. The first collar portion can define a pocket. An arm of the second collar portion can be receivable in the pocket to couple the first collar portion and the second collar portion to form an assembled collar. The first collar portion can be movable relative to the second collar portion while the arm of the second collar portion is received in the pocket of the first collar portion.
Some embodiments disclosed herein are directed to packaging including a first collar portion configured to conform to a periphery of a first product portion, and a second collar portion configured to conform to a periphery of a second product portion. The first collar portion can define a first pocket and a second pocket. A first arm of the second collar portion can be receivable in the first pocket, and a second arm of the second collar portion can be receivable in the second pocket to form an assembled collar. The assembled collar can forms a closed loop and resist inward deflection.
Some embodiments disclosed herein are directed to a protective film including a polyethylene terephthalate (PET) carrier, a first adhesive portion, a second adhesive portion, and a paper layer. The PET carrier can have a thickness between 0.001 mm and 0.015 mm. The first adhesive portion can be disposed on a first side of the PET carrier and be formed of a low-tack adhesive. The second adhesive portion can be disposed on a second side of the PET carrier opposite the first side of the PET carrier. The second adhesive portion can be formed of a high-tack adhesive. The paper layer can be attached to the second adhesive portion. The paper layer, the second adhesive portion, the PET carrier, and the first adhesive portion can be formed to have a non-developable surface.
Some embodiments disclosed herein are directed to a flat sheet for forming a packaging component. The flat sheet can include a PET carrier, a first adhesive portion, a second adhesive portion, and a paper layer. The PET carrier can have a thickness between 0.001 mm and 0.015 mm. The first adhesive portion can be disposed on a first side of the PET carrier and be formed of a low-tack adhesive. The second adhesive portion can be disposed on a second side of the PET carrier opposite the first side of the PET carrier. The second adhesive portion can be formed of a high-tack adhesive. The paper layer can be attached to the second adhesive portion.
Some embodiments disclosed herein are directed a method of forming a film including operations of forming a flat sheet and pressing the flat sheet to form a shape having a non-developable inner surface. The flat sheet can include a PET carrier, a first adhesive portion, a second adhesive portion, and a paper layer. The first adhesive portion can be disposed on a first side of the PET carrier and be formed of a low-tack adhesive. The second adhesive portion can be disposed on a second side of the PET carrier opposite the first side of the PET carrier. The second adhesive portion can be formed of a high-tack adhesive. The paper layer can be attached to the second adhesive portion.
The disclosure will be readily understood by the following detailed description in conjunction with the accompanying drawings, wherein like reference numerals designate like structural elements, and in which:
Reference will now be made in detail to representative embodiments illustrated in the accompanying drawings. It should be understood that the following description is not intended to limit the embodiments to one preferred embodiment. To the contrary, it is intended to cover alternatives, modifications, and equivalents as can be included within the spirit and scope of the described embodiments as defined by the appended claims.
Packaging for retail products is subject to many different considerations, including securely and safely maintaining the product (e.g., while in transport), allowing a purchaser to easily access their product once purchased, presenting the packaged product to the user in a welcoming way, and being made of materials that are robust enough not only for these uses, but for re-use by the purchaser if desired, while also being readily recyclable and otherwise environmentally friendly. These considerations may result in packaging solutions that depend on the nature and characteristics of the product being packaged, and can result in development of multiple different packaging features that can independently be of value in packaging a product, while also being valuable for their use together.
For example, a product such as a head-mounted display may include smooth surfaces (e.g., glass or other polished surfaces) that should be protected while packaged and a strap forming a loop that surrounds a space that should be maintained while packaged. And to minimize relative movement of such a product it may be beneficial for components of such packaging to be maintained in position with one another. To these and other ends as will be described in more detail below, some embodiments discussed herein relate to removable tear strips that help keep outer portions of the packaging secure and thereby maintain relative positioning of internal packaging components. Some embodiments relate to a collar support system that helps maintain the relative positions of portions of a product that form a loop. And some embodiments relate to a protective film that can protect surfaces of a product. Such embodiments can be useful and practiced individually, and also in various combinations in the same packaging assembly.
Some embodiments of the present disclosure provide a removable tear strip that attaches a lid to a base box. When the tear strip is engaged, the tear strip can hold the lid and the base box together, thereby providing a clamping force between the lid and base box. In turn, this clamping force can help secure a product between a top tray and a bottom tray provided within the lid and base box structure. In some embodiments, the removable tear strip can leave a remnant on the lid or base box when the tear strip is removed. The remnant can be designed to have a desirable aesthetic appearance. As discussed in more detail below, the tear strip can also have characteristics that balance functional requirements, case of use, and recyclability.
Some embodiments of the present disclosure provide a packaging solution for products that include movable (e.g., flexible) portions. If moveable (e.g., flexible) portions of a product are left unsecured in packaging, the portions may move or flex (e.g., during transport), which can cause containment loss or undesirable forces on sensitive components of the product. On the other hand, if movable or flexible components are tightly constrained in packaging, undesirable forces may be applied to sensitive components of the product (e.g., during a drop event). Some embodiments described herein describe a collar system to support a product that includes movable (e.g., flexible) portions.
The collar system, when assembled, can be positioned within a closed loop of the product and can support the product by, for example, resisting inward deflection of the closed loop of the product or maintaining a space within the closed loop of the product. For example, in some embodiments, the collar system is used with a head-mounted display including a viewing portion and a strap portion that together form a closed loop. The collar system can be positioned within the closed loop formed by the viewing portion and the strap portion to support the head-mounted display by, for example, resisting inward deflection of the strap portion and viewing portion or maintaining a space within the closed loop formed by the viewing portion and the strap portion.
The collar system can include a first collar portion configured to conform to a first portion of a product (e.g., the viewing portion of the head-mounted display) and a second collar portion configured to conform to a second portion of the product (e.g., the strap portion of the head-mounted display). When assembled, the first collar portion and second collar portion can be movable (e.g., slidable or rotatable) relative to each other. Accordingly, the collar system can support the product while allowing the product portions (e.g., the view portion and the strap portion of the head-mounted display) to move relative to each other. Such relative motion can also allow the same collar design to be used to support different product sizes (e.g., head-mounted displays having different strap lengths).
Some embodiments of the present disclosure provide a protective film for a product. Some products, such as electronic devices, can include smooth and/or highly polished surfaces (e.g., glass surfaces) that can be aesthetic or functional. Placing protective films over these surfaces can help maintain and protect the surfaces during transport. However, some surfaces that are desirable to protect have complex shapes that are difficult to protect with a single film that covers the entire surface. For example, non-developable surfaces (i.e., double curved surfaces, or surfaces that are curved in two dimensions) often cannot be protected with a continuous film that covers the entire non-developable surface. The classic example of a non-developable surface is a globe, which is why world maps are often distorted in different ways, but the term can apply to any surface that cannot be flattened without distortion (e.g., shrinking, breaking, or creasing). Protective films are normally flat. For one to cover a non-developable surface, multiple film pieces are sometimes needed, the film is sometimes cut and folded to approximate the non-developable shape, or the film sometimes does not lie smoothly on the non-developable surface. A single, continuous film that covers an entire non-developable surface, however, may be aesthetically preferred. The challenges described above are present for both protective films made of plastic and protective films made primarily or entirely of paper. However, the challenges described above can be more severe for films made primarily or entirely of paper.
Some embodiments described herein provide a single film that is formed to have a non-developable surface. The film can be made primarily or entirely of paper that has been formed from its nominal, flat shape into a shape corresponding to the non-developable surface that it is to be applied to protect. This forming can be done so that there are no cuts or discontinuities within the film.
These and other embodiments are discussed below with reference to the accompanying figures. However, those skilled in the art will readily appreciate that the detailed description given herein with respect to these figures is for explanatory purposes only and should not be construed as limiting.
Packaging 1 can be finished packaging for containing and conveying a product 10 to a user. Product 10 can be, for example, an electronic device such as, for example, a head-mounted display, a smartphone, a tablet, a smart watch, a desktop computer, a monitor, a laptop, or a mouse, or can be a non-electronic device. In some embodiments, packaging 1 contains multiple products. For example, packaging 1 can contain an electronic device (such as, for example, one of the electronic devices listed above) and accessories for the electronic device (such as, for example, batteries, cables, cases, or product manuals).
In some embodiments, packaging 1 includes a base box 20, a lid 30, and trays 40 and 50, which together contain and secure product 10.
In some embodiments, as will be discussed in greater detail, packaging 1 includes a tear strip 60 to attach lid 30 to base box 20.
In some embodiments, as will be discussed in greater detail, packaging 1 includes a collar system 70 to support product 10.
In some embodiments, as will be discussed in greater detail, packaging 1 includes a film 80 to protect product 10.
In some embodiments, packaging 1 includes other packaging components (e.g., boxes, additional trays, sleeves, and wraps).
As mentioned, in some embodiments, packaging 1 includes base box 20 and lid 30. As shown in
In some embodiments, lid 30 can be lowered onto base box 20 such that side panels 302 of lid 30 are parallel to and external to side panels 202 of base box 20. In some embodiments, lid 30 entirely covers base box 20 when in a closed position such that the lower edges of side panels 302 are flush with base panel 204 of base box 20.
In some embodiments, packaging 1 includes a tray 40 to support or cushion product 10. Tray 40 can, for example, support or cushion product 10 from below. In some embodiments, tray 40 rests on or in base box 20 when packaging 1 is assembled. For example, as shown in
In some embodiments, tray 40 is a molded-fiber tray. In some embodiments, tray 40 includes multiple molded-fiber components stacked to form a single molded-fiber tray. For example, tray 40 can include 3 to 6 molded-fiber components stacked to form a single tray. The multiple molded-fiber components can allow tray 40 to define more complex or extreme three-dimensional shapes for recess 400 that cannot be formed as a single molded-fiber component using current technologies.
In some embodiments, packaging 1 includes a second tray 50 to support or cushion product 10. Tray 50 can, for example, support or cushion product 10 from above. In some embodiments, tray 50 is formed as part of lid 30 or attached to lid 30. In some embodiments, tray 50 defines a recess 500 to locate a portion of product 10 in an intended position relative to tray 50.
In some embodiments, tray 50 is a molded-fiber tray. In some embodiments, tray 50 includes multiple molded-fiber components stacked to form a single molded-fiber tray. For example, tray 50 can include 3 to 6 molded-fiber components stacked to form a single tray. The multiple molded-fiber components can allow tray 50 to define more complex or extreme three-dimensional shapes for recess 500 that cannot be formed as a single molded-fiber component using current technologies.
In some embodiments, base box 20, tray 40, lid 30, and tray 50 cooperate to secure product 10 and thereby limit or prevent movement of product 10 relative to base box 20 and lid 30. In the illustrated embodiment, for example, when packaging 1 is assembled, tray 50 is attached to an inside surface of top panel 304 of lid 30, and tray 40 is positioned in base box 20 such that movement of tray 40 relative to base box 20 is restricted. Accordingly, when lid 30 is placed over base box 20, tray 40 and tray 50 cooperate to secure product 10. In the illustrated embodiment, tray 40 holds product 10 from below, and tray 50 holds product 10 from above. However, the positioning of trays 40 and 50 relative to product 10 is not limited to the arrangement shown. For example, in other embodiments, tray 40 can hold product 10 from a side and tray 50 can hold product 10 from another side.
As shown in
For example, as shown in
In some embodiments, to help keep product 10 secure (e.g., between recesses 400 and 500 as described above) tear strip 60 is sufficiently inextensible such that tear strip 60 holds lid 30 and base box 20 together, and resists motion of lid 30 away from base box 20, when tear strip 60 is engaged. In some embodiments, tear strip 60 is sufficiently inextensible such that tear strip 60 pulls lid 30 toward base box 20 when tear strip 60 is engaged, thereby providing a clamping force between lid 30 and base box 20 when assembled together as packaging 1 packaging product 10. In turn, this clamping force can help secure product 10 between tray 40 and tray 50 as described above. Particularly for a relatively heavy product 10, the tear strip's strength and inextensibility provide secure positioning and clamping force to resist relative movement of base box 20 and lid 30 (and thus, in some embodiments, recess 400 and recess 500) even during such impact and vibration as may be attendant to transport and dropping during shipping.
In the illustrated embodiment, two tear strips 60 are provided to attach lid 30 to base box 20. However, any suitable number of tear strips 60 can be provided to attach lid 30 to base box 20. In some embodiments, a single tear strip 60 attaches lid 30 to base box 20. In some embodiments, three tear strips 60 attach lid 30 to base box 20. In some embodiments, four tear strips 60 attach lid 30 to base box 20.
As shown in
In the illustrated embodiment, tear strips 60 are provided on opposite sides of packaging 1. However, the placement of tear strips 60 is not limited to the placement shown. Rather, any suitable placement of tear strips 60 can be used.
In some embodiments, tear strip 60 includes a pull tab 605 that can be easily grabbed by a user when the user desires to remove tear strip 60. In the illustrated embodiment, pull tab 605 is positioned on second portion 602 of tear strip 60 (which is attached to lid 30). However, in other embodiments, pull tab 605 is positioned on first portion 600 of tear strip 60 (which is attached to base box 20).
As shown in
The structure of tear strip 60 is shown in
As shown, first portion 600 of tear strip 60 (which can be configured to attach to base box 20) can include a top sheet 604, a stiffener layer 608, and a tape layer 612, which can be, for example, a Minfeng tape layer. Stiffener layer 608 can be attached to an interior surface of top sheet 604 by a permanent adhesive 606, and tape layer 612 can be attached to an interior surface of stiffener layer 608 by a differential adhesive 610. Similarly, second portion 602 of tear strip 60 (which can be configured to attach to lid 30) can include top sheet 604, stiffener layer 608, and tape layer 612. Stiffener layer 608 can be attached to an interior surface of top sheet 604 by permanent adhesive 606, and tape layer 612 can be attached to an interior surface of stiffener layer 608 by differential adhesive 610.
As shown in
In some embodiments, top sheet 604 includes a tear path 614 between first portion 600 and second portion 602. Tear path 614 can include perforations, score lines, or other features designed to allow easy and/or guided tearing of top sheet 604 during removal of tear strip 60.
Returning to
As shown, for example in
As shown in
As shown in
Due to the destructive nature of the tearing of top sheet 604, tear strip 60 may not be reattachable to base box 20.
As shown in
In some embodiments, tape layer 612 of second portion 602 is designed such that tape layer 612 has a desired aesthetic appearance when left as a remnant after the remainder of second portion 602 is removed from lid 30. In some embodiments, tape layer 612 of first portion 600 is designed such that tape layer 612 has a desired aesthetic appearance when left as a remnant after the remainder of first portion 600 is removed from base box 20. For example, in some embodiments, tape layer produces a pattern (such as, for example, spaced dots or lines) or a particular shape (such as, for example, a wavy line or letters) when left as a remnant after the remainder of first portion 600 is removed from base box 20.
As mentioned, in some embodiments, packaging 1 includes a collar system 70 (shown enlarged in
As shown in
If movable portion 106 is left unsecured in packaging, movable portion 106 may move relative to other portions of product 10 while packaged, which could cause containment loss or undesirable forces on portions of product 10. On the other hand, tightly constraining movable portion 106 in packaging might result in undesirable forces on product 10 during transport. For example, in the illustrated embodiment, strap portion 106 can be attached to viewing portion 104 via a magnetic attachment mechanism, and providing too rigid of a support structure for product 10 could cause viewing portion 104 to detach from strap portion 106 during transport (e.g., during a drop event). Accordingly, collar system 70 provides support to product 10 (including movable portion 106 and other portions of product 10) while allowing movable portion 106 to move relative to other portions 104 of product 10.
As shown in
As shown in
As shown, first collar portion 700 can define a pocket 704. Pocket 704 can have an open end 707 (positioned, for example, at an end of first collar portion 700) and extend along a length of first collar portion 700 toward a center of first collar portion 700.
In some embodiments, pocket 704 has an end 708 opposite open end 707. In some embodiments, end 708 is closed. In some embodiments, open end 707 is connected to end 708 by two closed sides 710, which can be straight, curved, stepped, or some combination thereof. In some embodiments, end 707 is taller than closed end 708. Accordingly, in some embodiments, pocket 704 has a trapezoidal shape.
In some embodiments, first collar portion 700 is formed of multiple layers which together define pocket 704. For example, as shown in
In some embodiments, first collar portion 700 includes two or more pockets 704. For example, in the illustrated embodiment, first collar portion 700 includes one pocket 704 on one side of first collar portion 700 (e.g., a left side of first collar portion 700) and another pocket 704 on another side of first collar portion 700 (e.g., a right side of first collar portion 700). In some such embodiments, pockets 704 all have the same size and shape. However, in other embodiments, pockets 704 have different sizes or shapes.
As shown in
As shown in
In some embodiments, arm 706 of second collar portion 702 is configured to extend across at least 20% of a maximum height of pocket 704 when received in pocket 704. In some embodiments, arm 706 of second collar portion 702 is configured to extend across at least 50% of the maximum height of pocket 704 when received in pocket 704. In some embodiments, arm 706 of second collar portion 702 is configured to extend across at least 90% of the maximum height of pocket 704 when received in pocket 704.
In some embodiments, second collar portion 702 includes two or more arms 706 that are receivable within respective pockets 704 of first collar portion 700. For example, in the illustrated embodiment, second collar portion 702 includes a main body 716, a first arm 706 extending from one side main body 716 (e.g., on a left side of second collar portion 702) and another arm 706 extending from another side of main body 716 (e.g., on a right side of second collar portion 702). In some such embodiments, arms 706 all have the same size and shape. However, in other embodiments, arms 706 have different sizes or shapes.
In embodiments in which first collar portion includes two or more pockets 704 and second collar portion 702 includes two or more arms 706 that are receivable within respective pockets 704 of first collar portion 700, first collar portion 700 and second collar portion 702 can be coupled by inserting arms 706 of second collar portion 702 into respective pockets 704 of first collar portion 700.
As shown in
In some embodiments, second collar portion 702 is rotatable relative to first collar portion 700 when arm 706 of second collar portion 702 is received in pocket 704 of first collar portion 700. For example as shown by arrows 718 in
In some embodiments, first collar portion 700 is formed of paper. For example, first collar portion 700 can be formed of paperboard, Solid Bleached Sulfate (SBS), Solid Unbleached Sulfate (SUS), other paper-based products, or a combination thereof. In embodiments in which first collar portion 700 is formed of multiple layers, each layer can be formed of paper. For example, an outer layer can be formed of SBS, an inner layer can be formed of SBS, and an inner layer can be formed of SUS.
In some embodiments, second collar portion 702 is formed of paper. For example, second collar portion 702 can be formed of paperboard, SBS, SUS, other paper-based products, or a combination thereof. In embodiments in which second collar portion 702 is formed of multiple layers, each layer can be formed of paper. For example, one or both layers can be formed of SBS.
In some embodiments, first collar portion 700 or second collar portion 702 includes a molded fiber portion 722. A molded-fiber portion 722 can, for example, provide additional rigidity to collar portion 700 or 702, or allow collar portion 700 or 702 to have a more complex shape in order to conform to a periphery of the respective product portion. In the illustrated embodiment, for example, second collar portion 702 includes a molded-fiber portion 722 that conforms to a periphery of strap portion 106 of head-mounted display 10.
In some embodiments, collar system 70 is part of a modular packaging system used with a product 10 that includes modular parts. For example, in some embodiments in which product 10 is a head-mounted display, various viewing portions of the head-mounted display can be paired with various strap portions of the head-mounted display. The various viewing portions and the various strap portions can, for example, vary in terms of their size or shape. Accordingly, different collar portions can be provided to accommodate different viewing portions or strap portions. In some embodiments, one collar portion can accommodate a subset of the various viewing portions such that a different collar portion is not needed for each of the various viewing portions. For example, one collar portion can accommodate several different larger viewing portions, and another collar portion can accommodate several different smaller viewing portions. In some embodiments, one collar portion can accommodate a subset of the various strap portions such that a different collar portion is not needed for each of the various strap portions. For example, one collar portion can accommodate several different larger strap portions, and another collar portion can accommodate several different smaller strap portions. In this way, the total number of different packaging components needed to accommodate the various viewing portions and the various strap portions is reduced relative to a system in which each of the various viewing portions and each of the various strap portions requires a different collar portion.
As shown in
Similarly, in some embodiments, the modular packaging system includes a second collar portion 702 with arm 706 (shown in
As mentioned, in some embodiments, packaging 1 includes a film 80 (shown enlarged in
In the illustrated embodiment, non-developable surface 800 of film 80 conforms to non-developable surface 100 of product 10. As shown, non-developable surface 800 of film 80 can be concave, and non-developable surface 100 of product 10 can be convex, which conforms to non-developable surface 100 of product 10. However, in other embodiments, non-developable surface 800 of film 80 can be convex and conform to a non-developable curve 100 of product 10 which is concave. In still other embodiments, non-developable surface 800 of film 80 can include a combination of concave, convex, or flat portions.
As shown in
In some embodiments, non-developable surface 800 curves 90 degrees or more in at least two planes. In some embodiments, the at least two planes form an angle therebetween of at least 45 degrees (e.g., 90 degrees). In some embodiments, non-developable surface curves 135 degrees or more in at least two planes. In some embodiments, the at least two planes form an angle therebetween of at least 45 degrees (e.g., 90 degrees). In some embodiments, non-developable surface curves 180 degrees or more in at least two planes. In some embodiments, the at least two planes form an angle therebetween of at least 45 degrees (e.g., 90 degrees). For example, as shown in
In some embodiments, a cavity formed by non-developable surface 800 can have a width 820 between 100 mm and 225 mm, a height 822 between 50 mm and 125 mm, and a depth 824 of at least 10 mm. In some embodiments, a cavity formed by non-developable surface 800 has a depth 824 of at least 20 mm. In some embodiments, a cavity formed by non-developable surface 800 has a depth 824 of at least 40 mm.
In some embodiments, film 80 is removably attached to product 10 (e.g., via a low-tack adhesive) when packaging 1 is assembled with product 10. This can, for example, help protect product 10 prior to purchase (e.g., during transport) by ensuring that film 80 is properly positioned to protect product 10 while allowing a consumer to remove film 80 from product 10 to use product 10.
In some embodiments, film 80 includes a pull tab 816 to help a consumer remove film 80 from product 10. In embodiments in which film 80 is removably attached to product 10 via a low-tack adhesive, for example, pulling pull tab 816 away from product 10 can cause the adhesive to release from product 10, thereby allowing film 80 to be removed from product 10. In the illustrated embodiment, pull tab 816 is attached to an upper perimeter of film 80. However, pull tab 816 can be attached to any suitable portion of film 80.
In some embodiments, when a user pulls pull tab 816 away from product 10, the three-dimensional shape of film 80 inverts. For example, a concave portion of film 80 can become a convex surface, or vice versa.
In some embodiments, film 80 has an overall thickness of between 0.1 and 0.3 mm, such as, for example, 0.2 mm.
Film 80 can be formed by pressing a flat sheet 802 into a three-dimensional shape having a curved (e.g., non-developable surface). The structure of flat sheet 802 is shown in
As shown, flat sheet 802 can include one or more layers of materials including a paper substrate 810 and a double-sided adhesive 803, which can, for example, allow film 80 to be removably attached to product 10 as discussed. Double-sided adhesive can include a polyethylene terephthalate (PET) carrier 804, a first adhesive portion 806, and a second adhesive portion. As shown, PET carrier 804 can have a first side 812 and a second side 814 opposite first side 812. First adhesive portion 806 can be disposed on first side 812 of PET carrier 804, and second adhesive portion 808 can be disposed on second side 814 of PET carrier 804. Paper substrate 810 can be attached to second adhesive portion 808.
In some embodiments, PET carrier 804 has a thickness between 0.001 mm and 0.015 mm. In some embodiments, PET carrier 804 has a thickness between 0.003 mm and 0.005 mm. In some embodiments, PET carrier 804 has a thickness of 0.004 mm. The thickness of PET carrier 804 is thinner than a typical PET carrier of a double-sided adhesive. This minimal use of PET can be made possible while still providing sufficient protective characteristics and integrity by the inclusion of paper substrate 810. This minimal use of PET can also, for example, enable flat sheet 802 to be more easily formed to have a non-developable surface, or can enable film 80 to better hold its shape after forming relative to inclusion of a thicker PET layer.
In some embodiments, first adhesive portion 806 is formed of a low-tack adhesive, and second adhesive portion 808 is formed of a high-tack adhesive (e.g., a permanent adhesive or an adhesive that is higher-tack than the low-tack adhesive of first adhesive portion 806). In some such embodiments, second adhesive portion 808 (the high-tack adhesive portion) is attached to paper substrate 810 and first adhesive portion 806 (the low-tack adhesive portion) is attached to product 10 when packaging 1 is assembled with product 10. This differential can, for example, allow film 80 to be removably attached to product 10 as discussed above.
In some embodiments, paper substrate 810 is flat before applying double-sided adhesive 803 to form flat sheet 802. In some embodiments, paper substrate 810 is formed of a paper comprising regenerated cellulose. For example, paper substrate 810 can be formed of the paper sold under the trademark PAPTIC®. In some embodiments, paper substrate 810 has a thickness between 200 and 300 GSM, such as 240 GSM. As mentioned, paper is not a material that is readily formable into a non-developable shape since it begins as a flat sheet and is prone to tearing rather than conforming to a non-developable shape. However, the inventors have discovered that paper formed of regenerated cellulose, including the papers formed of regenerated cellulose described above, can be made to deform without tearing under certain molding conditions which will be described.
In some embodiments, flat sheet 802 includes a release liner 818 attached to first adhesive portion 806. Release liner 818 can, for example, be a paper-based release liner. Release liner 818 can be removed from film 80 to attach film 80 to product 10 as discussed above.
Operation 902 includes applying adhesive to a paper substrate. The adhesive can be, for example, a double-sided adhesive including PET carrier 804, first adhesive portion 806, and second adhesive portion 808 discussed above. The paper substrate can be, for example, paper substrate 810 discussed above. The adhesive can be applied to the paper substrate through a lamination process. The paper substrate can be a flat sheet both before and after application of the adhesive.
Operation 904 includes pressing the paper substrate with adhesive applied to form a three-dimensional shape having a non-developable surface. Pressing the substrate with adhesive applied can include, for example, pressing the substrate with adhesive applied between two sides of a mold. In some embodiments, an inner surface of one side of the mold corresponds to the non-developable surface shape. In some embodiments, the substrate with adhesive applied is pressed for 6 to 10 seconds, such as for 8 seconds. In some embodiments, the substrate with adhesive applied is pressed with a heated tool, which can be heated to between 80 and 100 degrees C., such as to 90 degrees C.
As mentioned, paper is not a material that is readily formable into a non-developable shape since it begins as a flat sheet and is prone to tearing rather than conforming to a non-developable shape. However, the inventors have discovered that paper formed of regenerated cellulose can be made to deform without tearing under certain molding conditions, including the application of heat, time, and pressure described above.
Operation 906 includes cutting the three-dimensional shape to have a desired perimeter. Cutting the three-dimensional shape can include, for example, die cutting the three-dimensional shape.
