Description

FIELD OF THE INVENTION

The current invention generally relates to recyclable plastic products, including recyclable food grade plastic products, such as cups and containers, manufactured with virgin plastic, post-consumer recycled plastic, bioplastic, and/or combinations thereof, and wash away labels and to methods of making, using, and recycling same.

BACKGROUND OF THE INVENTION

Single-use plastics are goods that are made primarily from fossil fuel-based chemicals (petrochemicals) and are meant to be disposed of right after use—often, in mere minutes. Single-use plastics are most commonly used for packaging, and food and beverage serviceware, such as bottles, wrappers, straws, bags, cups, and containers.

As a result of society's reliance on these single-use plastics, post-consumer plastic waste is accumulating at a staggering rate. There are trillions of recyclable food grade plastic products, including for example, food and beverage containers and cups, which are used and disposed of annually around the world. Millions of pounds of post-consumer plastic waste end up in landfills every year. We produce 300 million tons of plastic each year worldwide, half of which is for single-use items. In the U.S. alone, 54 billion pounds of plastic are landfilled each year. Plastic also ends up in our environment—i.e., rivers, oceans, and beaches—with devastating effects to wildlife and the climate.

Recycling more plastic, more frequently, advantageously reduces its footprint. Polyethylene terephthalate (PET), one of the most commonly recycled plastics and the material that is used to manufacture most food and beverage containers and cups, can be turned into everything from polyester fabric to automotive parts. But, currently, more than 90% percent of all plastic isn't recycled at all. Single-use plastics in particular—especially small items like straws, bags, and cutlery—are traditionally hard to recycle because they fall into the crevices of recycling machinery and therefore are often not accepted by recycling centers.

Additionally, while there are existing methods for recycling bottle-grade, injection molded and blow molded PET plastic products (e.g., PET bottles and jars), there are no existing processes for recycling thermoform plastic products, such as food and beverage containers, which are commonly formed of PET and other plastics having a lower intrinsic viscosity (IV) measurement than bottle-grade products. Thermoform containers pose a number of recycling challenges that are distinct from non-thermoform plastic products (such as plastic bottles).

First, the inconsistency in plastic resins utilized for manufacturing thermoformed products is one major obstacle for recycling. While PET is the favored resin in the recycling industry, a significant proportion of thermoforms are made from oriented polystyrene (OPS), high density polyethylene (HDPE), and polypropylene (PP). Additionally, thermoform manufacturers often employ PET alternatives like PLA, and PETG, and bioplastic, further complicating the recycling process.

Labeling, and the use of adhesives to secure labels to the plastic, pose additional obstacles to recycling thermoforms. There is generally a lack of uniformity of labels used on thermoformed plastic containers, which can create technical complications in the process. Additionally, due to the intended use of most thermoform containers (for example being exposed to produce misters, refrigeration, condensation, and close physical contact with other containers, the label adhesives used on thermoformed products is generally much more aggressive than the glue used on plastic bottles. This characteristic makes the removal of labels from PET and other plastic surfaces and flakes more challenging. Furthermore, the residues from these adhesives can contaminate washing solutions, hampering the recycling process.

Additionally, Intrinsic Viscosity (IV), a measure of plastic's tensile strength and elasticity, differs notably between PET thermoforms and non-thermoformed containers such as bottles. This variance makes it difficult to process bottles and thermoforms together.

Finally, the thinness of thermoform containers causes a “bulk density” concern in the reclamation process. Recycled plastics are generally ground into flake form prior to washing, and if the flakes are too light, they can have problems flowing through the wash and decontamination processes. These challenges generally prevent thermoformed plastic products from being recycled, much less being reclaimed into FDA-approved food grade (i.e., food safe) plastic that can be manufactured back in to new recyclable food grade plastic products.

Moreover, there are currently no recycling processes specifically designed to recycle recyclable food grade plastic products that have text, graphics, or images printed thereon. Existing ink systems used to print text, graphics, or images on plastic items generally render the plastic unsuitable for being recycled under any circumstances.

In particular, conventional “direct print” ink systems which are generally used to print text, graphics, or images directly on plastic products cannot be easily removed to permit recycling of the plastic items themselves. Attempts to recycle such printed plastic products, in general, result in the printing ink contaminating the post-consumer plastic recycle stream. Likewise, a common challenge with conventional printed labels when recycling plastic products is that the label material, adhesive, and ink can contaminate the recycled plastic. Such contamination prevents these items from being recycled into FDA-approved food grade (i.e., food safe) plastic that can be manufactured back in to new recyclable food grade plastic products.

Thus, a need exists for recyclable thermoformed food grade plastic products, such as food and beverage containers and cups. Likewise, a need exists for recyclable food grade plastic products with printed text, graphics, or images that can be easily removed such that the plastic product may be recycled into FDA-approved food grade plastic that is capable of being reused in new food grade products. Likewise, a need exists for methods of making and recycling recyclable thermoformed food grade plastic products with printed text, graphics, or images that can be easily removed such that the plastic product may be recycled into FDA approved food grade plastic that is capable of being reused in new recyclable food grade products.

Additionally, there is a need for recyclable food grade plastic products manufactured, at least in part, from recycled post-consumer plastic and/or bioplastic. This “circular” sustainability effort will advantageously allow millions of pounds of post-consumer plastic waste to be diverted from landfills and the environment every year and reused.

In one form, the outer film of the wash away label 101 may be suitable for surface printing or reverse printing, for example but not limited to, by UV inkjet, UV letterpress, and Flexographic UV, solvent, and water-based inks. As described above, the wash away label 101 may be surface printed or reverse printed. It may also be trapped, or otherwise contained, with the ink sandwiched between the outer film and the wash away adhesive layer, or between the first and second layers of the outer film.

The wash away labels 101 may also include additional label materials and layers including for example, transparent polyethylene film (PE film), transparent polyethylene film (PE film) manufactured from recycled granulate, transparent polypropylene film (PP film), white polypropylene film (PP film), and/or wet-strength and alkali-resistant paper, and the like. Other types of labels and label materials are within the scope of the invention.

In one preferred form, the wash away labels 101 may be clear and transparent. They are preferably designed to give the appearance that any text, graphics, or images printed thereon are printed directly on the plastic products. The margins of the label preferably may blend seamlessly into the container, so that the label is not visible unless inspected closely. In another form, the wash away label may be another color to either blend with or stand out from the color of the plastic product.

In another form, the wash away labels 101 may include customizable text, graphics and/or images. They may include, for example but are not limited to, brand indicators such as business, venue, or product names and/or logos, sports team names or logos, special event names, locations, and dates, and the like. They may also include, for example, promotional URLs or QR codes to prompt the consumer to action (for example: “enjoy 25% off if purchase is made by a certain date or time” or “enter to win” and the like).

In accordance with one aspect, the wash away off adhesive may include a wash-off acrylic emulsion. The wash away adhesive is advantageously designed to wash off under specific conditions, allowing recycling of the PET container or cup that it was applied to. In accordance with another aspect, the wash away labels 101 are advantageously resistant to temperature fluctuations, such as those associated with submersion in ice water or room temperature water, and UV light. They may be constructed to withstand humid and hot environments and normal washing conditions. These characteristics preferably render the wash-off labels 101 easier or more favorable to work with than traditional labels that use wet glue products.

In accordance with another aspect, as discussed in more detail with the washing step 15 of the process 10 of FIG. 1, the wash away labels 101 are preferably readily removed as they may advantageously shrink and peel off on their own during the washing process, minimizing waste volume and maximizing the ability to reuse the plastic products.

In another aspect, the inner liner layer of the wash away label may be rolled away as the wash away label 101 is applied to the plastic product. In one form, the inner liner is manufactured from at least a portion of recycled, post-consumer plastic. In another form, the inner liner that is removed from the wash away label during application is itself recyclable.

The recycling of used, or post-consumer, food grade plastic products is not further described with reference to the process 10 of FIG. 1.

In accordance with another aspect, the post-consumer plastic products of the present invention may advantageously be collected 14 in predetermined receptacles. In one form, the receptacles may include, for example, openings shaped and configured to accept the particular plastic products, for example, cups. The collected post-consumer plastic products may then be cleaned and recycled in accordance with standard recycling processes. In one form, the post-consumer plastic products may be sorted, bailed, and washed 15 to remove the wash away labels and any surface contamination from the plastic. The wash away labels' ease of removal, including separating residue, impurities, and inks, facilitates the recycling process so that it is smooth and rapid.

In one form, the wash away labels may advantageously be removed 15 in a hot water bath at temperatures at or below industry standard, for example, at about 80-100° F. In another form, the wash away labels may be removed 15 by being exposed to a solution of about 1-10% caustic acid and warm water. During the washing process 15, the wash away label may advantageously peel off and roll up, thereby separating itself from the plastic product with little to no effort.

Either before or after washing the wash away labels off 15, the plastic products may be processed by shredding, grinding, and the like to provide flake. The flake may then be further processed 16, for example, by applying detergent and/or caustic acid, rinsing, drying, sifting the fines, and/or sorting the flake to provide clean washed thermoform flake (“CWTF”). The CWTF may then be further processed 17 by, for example, but not limited to, decontaminating, crystallizing, and/or solid-stating the clean washed thermoform flake to provide decontaminated FDA-approved food grade plastic flake. In one preferred form the CWTF is dried and crystallized under negative pressure to decontaminate and solid-state the CWFT and form decontaminated, FDA-approved food grade plastic flake. The decontaminated, FDA-approved food grade plastic flake may then be contained in a controlled environment (i.e., free from moisture and/or other contaminants), by for example, but not limited to, applying a nitrogen blanket to the decontaminated flake, and then may be extruded to provide FDA-approved food grade plastic pellets or sheet. The resulting FDA-approved food grade plastic pellets or sheet may then be advantageously used to manufacture new FDA-approved food grade plastic products 18.

In accordance with another aspect, the post-consumer plastic products of the present invention may be recycled using conventional methods, including for example but not limited to, the following. PET and polypropylene (PP) may be recycled by Mechanical Recycling Coupled with Plastic Flake Decontamination as described above. OPET and PET may also be recycled using Liquid State Polycondensation (LSP). PET, PP, and HDPE may be recycled using Pyrolysis.

Advantageously, the “food grade” plastic that is extruded into new recycled plastic sheet and/or pellets may then be used to manufacture new recyclable food grade plastic products. This “circular” sustainability effort will advantageously allow millions of pounds of post-consumer plastic waste to be diverted from landfill and the environment every year and reused in new recyclable food grade plastic products.

While the invention has been described in connection with what is presently considered to be the most practical and preferred embodiments, it is to be understood that the invention is not to be limited to the disclosed embodiment, but on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
