The invention relates generally to the packaging of corrugated paperboard and, in particular, to paper banding used to secure sheets of corrugated paperboard together. The paper banding is made of completely recyclable material, can be wrapped around the corrugated paperboard with minimal damage to edges of the paperboard, and is configured to allow for printing on the paper banding.
Corrugated paperboard products are typically stacked to a desired height and then wrapped into packages for transportation with multiple thin strips of plastic strapping. Depending on the number of sheets of paperboard, the dimensions of the stacked paperboard, and the weight of the stacked paperboard, multiple strips of plastic strapping can be wrapped horizontally and vertically relative to the stacked packages. These strips are then sealed together using heat or vibration, or by applying glue to secure the ends of the plastic strips together to hold the sheets of corrugated paperboard in a secure package. The plastic strapping can be made of various plastic materials, including polypropylene, polyester, and other materials. These strips of plastic strapping are known for having high tensile strengths to resist stretching, snapping, and breaking when the package is transported from one location to another.
Once the package has been assembled, it can then be transported to a desired location. Upon arrival, the plastic strapping can easily be cut, torn, or otherwise disengaged to release the sheets of corrugated paperboard for future use. Unfortunately, because the materials used to create these pieces of plastic strapping, as well as the length and configuration of the plastic strapping upon removal, the plastic strapping is not traditionally recycled, but instead is simply thrown away and eventually deposited into landfills. In light of environmental concerns, alternative packaging materials are desired. Furthermore, especially for large retailers who acquire significant quantities of corrugated paperboard, the cost associated with disposal of these plastic strappings can be significant.
Additionally, although these strips of plastic strapping are durable, there are some negative aspects to using them to secure packages of corrugated paperboard together. More specifically, the strips of plastic strapping that are applied to a package of corrugated paperboard typically have a very narrow width. As a result, there are pressure points associated with the plastic strapping, especially around any edges of the package of corrugated paperboard. For instance, front and back edges of the package located at the top and bottom of the package are prone to pressure from the plastic strapping. This is exacerbated due to the sharp edges of the plastic strapping and the tight fit of the plastic strapping relative to the package to ensure the package remains intact. As a result, oftentimes at least one sheet, and in some instances multiple sheets of corrugated paperboard that are adjacent to the edges may be damaged when the package is moved and transported. One way that this damage can be minimized is by applying dunnage about the edges. Dunnage may be additional pieces of corrugated paperboard, or other materials, that are wrapped around the edges of the package materials, and more specifically the edges of the package that are subject to pressure and contact with the plastic strapping. The strips of plastic strapping are then wrapped around the dunnage, such that the strapping primarily or only directly contacts the dunnage. Thus, instead of potentially damaging the sheets of corrugated paperboard, the strips of plastic strapping damage the dunnage, which is not part of the ordered corrugated paperboard product, and thus can be disposed of upon arrival of the package. Of course, use of dunnage results in additional waste, which is generally undesirable for environmental concerns.
Additionally, when a package of corrugated paperboard is created, a label is traditionally printed onto a sheet and then applied to the package. The label provides various transportation information, for instance, a bar code, a destination address, an order number, a description of the goods and associated dimensions, and the like. These labels are separately generated and then applied to the package. However, more efficient ways of using and applying the labels or printing directly on the material used to contain the units is desired.
What is therefore needed is an alternative way to secure sheets of corrugated paperboard together. What is further needed is different straps that can be secured around the sheets of corrugated paperboard to hold the sheets together. What is also needed is a strapping material that is completely recyclable, while also having sufficient strength to hold the sheets of corrugated paperboard securely together during transportation. What is additionally needed is a strapping material that minimizes or eliminates damage to any of the sheets of corrugated paperboard, especially at edges where the strapping materials will form pressure points relative to the package. What is further needed is strapping materials that can include a customized label to summarize the package and various transportation information.
By way of summary, the present invention is directed to a system and method for packaging a plurality of sheets. For instance, the present invention may be used to package a plurality of sheets of corrugated paperboard together.
In accordance with a first aspect of the invention, the system may include a plurality of sheets of corrugated paperboard that are stacked on top of one another, at least one strip of paper banding, and a fastener. The at least one strip of paper banding may have a first end, a second end, and a body therebetween and may be wrapped around the plurality of sheets of corrugated paperboard. The fastener may be applied to the first end to secure the first end to the body or the second end. For instance, the fastener may be a variety of different materials including hot adhesive or glue, cold adhesive or glue, staples, pins, and the like. As a result, the at least one strip of paper banding may hold the plurality of sheets of corrugated paperboard together during transportation. For instance, the plurality of sheets that form the package may weigh less than 5,000 pounds.
In accordance with another aspect of the invention, the at least one strip of paper banding, as well as the fastener, may be recyclable. Additionally, the at least one strip of paper banding, as well as the fastener, may be substantially weather and water resistant. Further still, a shipping label may be affixed to one of the strips of paper banding.
In accordance with another aspect of the invention, the at least one strip of paper banding may have a width that prevents damage of the plurality of sheets of corrugated paperboard. For instance, each strip of paper banding may have a width of at least 3 inches. Further, each strip of paper banding may have a width of at least 4 inches. Further still, each strip of paper banding may have a width of at least 8 inches. Alternatively still, each strip of paper banding may be folded over at least one time relative to the length of the strip to strengthen the strip of paper banding, while also reducing the width of the strip. For instance, the strip of paper banding may be six inches in width, but then folded over two times to result in a paper banding having two inches in width and triple the thickness. The strip of paper banding may be folding over a single time, reducing the width in half while doubling the thickness. Additional folds may be added to further strength the strips of paper banding. This in turn increases the tensile strength that the strip of paper banding can withstand before failure. Additionally, each strip of paper banding may have a thickness of at least 10 thousandths of an inch. Furthermore, each strip of paper banding may have a thickness of at least 18 thousandths of an inch.
In accordance with a further aspect of the invention, multiple strips of paper banding may be provided. For instance, a first strip of paper banding and a second strip of paper banding may be provided. These strips may be at least 12 inches from one another. Further still, the strips may be separated by an even greater distance, for instance, 24 inches. Additionally, at least one strip of paper banding may be vertically oriented, and at least one strip of paper banding may be horizontally oriented.
In accordance with yet another aspect of the invention, some or all of the strips of paper banding may have a fiber scrim formed therein. This fiber scrim may provide additional reinforcement to each strip of paper banding. Again, the strips can also be folded over as discussed herein to further strengthen the strips.
According to another aspect of the invention, a method of packaging a plurality of sheets is provided. The method may include the steps of stacking a plurality of sheets of corrugated paperboard, after which at least one strip of paper banding is wrapped around the plurality of sheets. Additionally, the plurality of sheets of corrugated paperboard may be compressed, after which the at least one strip of paper banding may be wrapped around the plurality of sheets of corrugated paperboard. Once the strip has been wrapped around the plurality of sheets, a first end of the strip is affixed to a second end of the paper banding to form a package. For instance, an adhesive may be applied to the first end of the at least one strip of paper banding, after which the first end is secured to a portion of the at least one strip of paper banding. One the first end is affixed, the plurality of sheets of corrugated paperboard may be removed from the compression, allowing them to expand. As a result of this compression, the strips of paper banding are put into tension to help ensure that the plurality of sheets of corrugated paperboard stay together. Thereafter, the package is transported from a first location to a second location. Once the package arrives at the second location, the at least one strip of paper banding is broken. After this occurs, the plurality of sheets of corrugated paperboard may be separated. The method may also include the steps of taking measurements related to the plurality of sheets of corrugated paperboard. Once the measurements are taken, the number of strips and location of strips of paper banding may be determined. Additionally, a shipping label may be printed onto the at least one strip of paper banding. Further still, a reinforced scrim material may be installed into the at least one strip of paper banding. Also, a weather resistant material may be applied to the at least one strip of paper banding.
These, and other aspects and objects of the present invention will be better appreciated and understood when considered in conjunction with the following description and the accompanying drawings. It should be understood, however, that the following description, while indicating preferred embodiments of the present invention, is given by way of illustration and not of limitation. Many changes and modifications may be made within the scope of the present invention without departing from the spirit thereof, and the invention includes all such modifications.
A clear conception of the advantages and features constituting the present invention, and of the construction and operation of typical mechanisms provided with the present invention, will become more readily apparent by referring to the exemplary, and therefore non-limiting, embodiments illustrated in the drawings accompanying and forming a part of this specification, wherein like reference numerals designate the same elements in the several views, and in which:
In describing the preferred embodiment of the invention, which is illustrated in the drawings, specific terminology will be resorted to for the sake of clarity. However, it is not intended that the invention be limited to the specific terms so selected and it is to be understood that each specific term includes all technical equivalents which operate in a similar manner to accomplish a similar purpose. For example, the word connected, attached, or terms similar thereto are often used. They are not limited to direct connection but include connection through other elements where such connection is recognized as being equivalent by those skilled in the art.
The present invention and the various features and advantageous details thereof are explained more fully with reference to the non-limiting embodiments described in detail in the following description.
A system 10 of securing a plurality of sheets of corrugated paperboard 12 by using at least one, and oftentimes multiple strips of paper banding 14 is generally shown in the figures. The strips of paper banding 14 are made of specific materials and have specific dimensions to ensure that the strips 14 secure the sheets of corrugated paperboard 12 into a travel-ready packaging 16. Additionally, the strips of paper banding 14, as well as any other components associated therewith, are made of 100% recyclable materials. As a result, once the package 16 is safely delivered to a desired location, the strips of paper banding 14 can quickly and easily be disengaged from the packaging 16, after which they can be recycled. In turn, this satisfies environmental concerns on behalf of the receiver of the packaging 16, and also provide the benefit of minimizing costly hauling of waste materials that previously were used to band the sheets of corrugated paperboard together. Furthermore, the strips of paper banding 14 may be made of previously-recycled materials to further ensure minimal environmental impact of use.
Each of the strips of paper banding 14 have a first end 18, a second end 20, a body 21 located between the first end 18 and the second end 20, a top side 22, and an under side 24. As shown, each strip 14 has a substantially consistent width, such that the strip of paper banding 14 forms a substantially elongate rectangle. When the package 16 is formed, the paper banding 14 may be wrapped around the package 16, after which the underside 24 of the first end 18 may be secured to the top side 22. The first end 18 may be secured to the top side 22 using a number of different fasteners (not shown). For instance, a glue or adhesive material, staples, or other fasteners may be used to ensure that the first end 18 is secured to the rest of the paper banding 14. To avoid damage to the underlying sheets of corrugated paperboard 12, preferably the fastener only has contact with portions of the strip of paper banding 14.
Additionally, each strip of paper banding 14 may be folded onto itself at least one time to change the paper banding 14 from one ply to multiple ply. For instance, a strip 14 may be folded over itself one time, resulting in a band that is half as wide, but twice as thick as shown in
The strips of paper banding 14 are configured to secure a plurality of sheets of corrugated paperboard 12 into a large number of different package sizes. For instance, the strips of paper banding 14 may be configured to secure packages 16 together having at least 250 pounds or material inclusive of multiple stacks that may weigh even more than 5,000 pounds of corrugated paperboard 12. Additionally, the strips of paper banding 14 may be configured to secure packages 16 having a wide range of dimensions. For instance, the strips of paper banding 14 may be used to secure packages 16 having a width of at least 110 inches, and oftentimes even larger. Additionally, the strips of paper banding 14 may be used to secure packages 16 having a length of between 20 and 240 inches. Further still, the strips of paper banding 14 may be used to secure packages 16 together having a height of 12-60 inches, and in some instances even taller packages. As shown in
As shown in
Alternatively, the specific width of these strips of paper banding 14 may be varied based on a number of factors. For instance, different widths of strips 14 may be provided depending on the shape of the desired package 16, the weight of the sheets of corrugated paperboard 12, and the number of strips of paper banding 14 that will be applied. Again, the strips of paper banding 14 may be folded over one or more times to result in an appropriately wide strip 14 having an increased thickness. When this is desired, the band may come in double, triple, or more times the width of the ultimately desired strip.
Similarly, the thickness of the strips of paper banding 14 may be consistently used, or different thicknesses may be employed depending on factors mentioned above. Of course, in situations where a larger or heavier package 16 is being wrapped, thicker strips of paper banding 14 may be desired. To the contrary, where smaller packages 16 are being wrapped, thinner strips of paper banding 14 may be desired. By way of example and not limitation, the strips of paper banding 14 may be at least 10 thousandths of an inch in thickness. The strips of paper banding 14 may be thicker, for instance, at least 0.012 inches, 0.014 inches, 0.016 inches, 0.018 inches, or even thicker. In yet other embodiments, the thickness of the strips may be between 0.006-0.24 inches in width. Again, a user may solely stock a single thickness of paper banding 14 based on average package loads, or the user may stock multiple thicknesses such that they are equipped to secure a variety of different packages 16 while maintaining efficiency of the paper banding 14. As described above, the thickness can also be changed by folding over the strip onto itself one or more times.
Like the width and thickness of the strips 14 that are being used, a user can determine the number of strips 14 that are required in light of a variety of different factors. Among others, these factors may include the height of the package 16, the width of the package 16, the weight of the package 16, and any number of other factors. Additionally, a user can determine whether solely vertical strips of paper banding 14 are needed, or if a combination of vertical and horizontal strips of paper banding 14 should be employed.
In addition to specifically selecting a paper banding 14 based on the width and thickness, the strips of paper banding 14 may be selected based on additional characteristics or additives. For instance, the strips of paper banding 14 may come with embedded scrim reinforcement 26. For instance, the paper banding 14 may come with layers of scrim reinforcement 26, which in turn makes for a more durable paper banding 14 product. By way of example, some or all of the strips of paper banding 14 may include fiber scrim reinforcement. Additionally, the strips of paper banding 14 may be made of materials that are weather resistant. For instance, 26#-90# containerboard may be used, whether it be with or without scrim enforcement. Similarly, the fastener, such as glue or adhesive, may similarly be selected to be weather resistant. Otherwise, a weather resistant spray may be applied after the strips 14 have been applied. This helps to ensure that the strips of banding 14 will remain intact despite various elements, including rain, snow, slush, ice, hail, humidity, and the like. Not only may these conditions be present when the packages 16 are moved in an outdoor environment, oftentimes transportation vessels may be contaminated by water or moisture in light of workers who are moving into and out of the vessel from an area where water may be present. Furthermore, other sprays or coatings may be used to enhance the characteristics of the strips of paper banding 14. For instance, a poly coating may be added that helps to assist in the strength and welding of the paper. Preferably this poly coating is recyclable and repulpable to minimize environmental impact.
In addition to providing structural support to the package 16, the strips of paper banding 14 may serve additional functions. For instance, at least one of the strips 14 may have a shipping label 28 printed thereon. Preferably, the strip 14 is at least 4% inches or more to ensure there is sufficient space for the label 28. The label 28 may contain a variety of important information, including shipping information, the delivery address, identifying information relating to the package, and the like. This is preferable over previous packages of sheets of corrugated paperboard, where the label would need to be separately created and then applied to either the dunnage or a side portion of the package.
Also, the present invention is also directed to a method of packaging the plurality of sheets of corrugated paperboard. The method is shown schematically in
