LDPE STRETCH FILM RECYCLING
LDPE Shrink Wrap
There’s money in shrink film. Recycle that used shrink film by baling it and selling us your bales or get it picked up in combination with one of our custom designed recycling programs. The larger the bale, the better the return. You can sell your bales directly to us, have us setup a baler or just have us pickup your loose film.
Stretch film is composed of linear low density polyethylene. Stretch film is used to secure contents stacked onto a pallet ready for shipment. Manufacturers and distributors consider stretch film one of the most costly waste byproducts. A stretch film recycling program offers a cost-effective solution to disposal. In fact, stretch film carries a high scrap market value. A stretch film recycling program requires a few steps to develop for your business needs.
The most common stretch wrap material is linear low-density polyethylene or LLDPE, which is produced by copolymerization of ethylene with alpha-olefins, the most common of which are butene, hexene and octene. The use of higher alpha-olefins (hexene or octene) gives rise to enhanced stretch film characteristics, particularly in respect of elongation at break and puncture resistance. Other types of polyethylene and PVC can also be used. Many films have about 500% stretch at break but are only stretched to about 100 – 300% in use. Once stretched, the elastic recovery is used to keep the load tight.
Stretch film is used widely in distribution, industry and even in your kitchen commonly known as “Saran Wrap.”
There are two methods of producing stretch wrap. 1) Blown: the resin is melted and blown out, it is air-cooled. This is a slower process but provides for higher quality. The cost of production is higher due to the quantity that can be produced per hour. 2) Cast: the film is passed over cooling rollers. This makes the cooling process quick. The quality is not as good as blown but more can be produced in an hour with lower costs.
Other properties such as break strength, cling, clarity, tear resistance, static discharge, etc. are also important.
Stretch film recycling is very cost-effective for companies as throwing it out in garbage is expensive. Stretch film can equal over 50% of your garbage bill. Recycle your stretch film in BC, Vancouver, Richmond, Surrey, Kelowna, Nanaimo, Okanagan, Alberta, Calgary, Edmonton, Washington State, Seattle, Everett, and Tacoma.
HOW PLASTIC FILM RECYCLING WORKS:
Recycling Plastic Film (LDPE resin) is a multi-step process that requires very specialized equipment. Essentially, a finished end product – like plastic pallet wrap – is chopped, washed, melted and extruded into plastic pellets. These plastic pellets are then sold to a plastic reprocessor, who will use them in a specific manufacturing process (such as blow molding in the case of plastic bottles or extrusion in the case of plastic lumber) to create a “new” or “recycled” plastic product.
LDPE plastic film recycling starts with inspection, which takes place at Blue Planet Recycling. This process is designed to weed out any foreign materials, contaminants or other plastics. Because plastics have different properties and characteristics, recycling involves the separation of different plastics by resin type.
After the plastic film is inspected, it is ground. This serves to clean the material and to get it into a more manageable size for the next few processes. Some dirtier or cross-contaminated materials may require separation by flotation, where certain types of plastic will rise to the top of the flotation tank and others, because of their higher densities, will sink.
From there, the plastic regrind is melted by heat and friction inside an extruder. The molten plastic passes through a screen where any remaining contaminants are filtered out. Little pellets emerge and are market ready.
We are committed to selecting local markets for our reclaimed products—we look for local uses and support North American manufacturing. Blue Planet Recycling Ltd. has a reputation for providing high quality cost-effective reclaimed resins for film, pipe, sheet extrusion and injection molding applications.
We offer a loose plastic film recycling pickup service. For larger volume generators we can install a baler and buy baled film from your facility or distribution network. We can service nationwide programs or individual stores in our service areas.
