Plastic film is a thin continuous polymeric material. Thicker plastic material is often called a sheet. These thin plastic membranes are used to separate areas or volumes, to hold items, to act as barriers, or as printable surfaces. Plastic films are used in a wide variety of applications. These include packaging, plastic bags, labels, building construction, landscaping, electrical fabrication, photographic film, film stock for movies and videotapes, to mention but a few.

Plastic film is typically defined as any plastic less than 10 mil thick. The majority of plastic films are made from polyethylene resin and are readily recyclable if the material is clean and dry. The resin coding system was originally intended for rigid plastic containers only.
Plastic film is essentially produced by flat and by blown film extrusion. In the case of flat film extrusion, the polymer is formed into a flat molten web by a so-called slit die, which has the function of distributing the melt in such a way that it emerges from the die with an even velocity distribution.
Plastic film – also known as plastic film packaging – is soft, flexible polyethylene (PE) packaging such as grocery, bread, zip-top and dry cleaning bags. It's also the wrap around many products including paper plates, napkins, bathroom tissue, diapers, and more.
During the recycling process, plastic film is brought into the facility in baled form and is then pulled apart by hand or by a guillotine. It is then fed into a shredder and water-fed grinder where it is cut into pieces. The film is then washed and inspected for contamination.
Common Types of Plastic
Plastic film is not accepted in the vast majority of curbside recycling programs. Plastic film is a type of soft plastic that is difficult to sort out and can easily gets tangled in recycling centre sorting machines.
We found that some plastic film does get recycled into other materials, but it is difficult to follow these film plastics into their next form. The entire recycling process is not well tracked, and thus, for the most part, we do not always know what becomes of the post-consumer plastics that are processed.
This material is durable, versatile, and FDA-approved food-safe. The hallmark of this material is its strength. Polyolefin (POF) shrink film is very thin yet incredibly strong. It has a high level of puncture resistance and seal-strength, which allows for a variety of irregular-shaped items to move through the supply-chain life cycle without issue.
High Density Polyethylene (HDPE)
High-density polyethylene (HDPE) or polyethylene high-density (PEHD) is a polyethylene thermoplastic made from petroleum.
Low Density Polyethylene (LDPE)
While similar to high-density polyethylene, LDPE has a lower density, as the name suggests. This means that it has less mass as compared to its volume.
Linear Low-Density Polyethylene (LLDPE)
This is one of the most commonly used films in the packaging industry! Of all of the polyethylene films, this is the most flexible. A blended form of LDPE, LLDPE offers more strength and conform-ability, making it perfect for stretching.
Polyethylene Terephthalate (PET, PETE)
PET is clear, tough, and has good gas and moisture barrier properties. As a raw material, PET is globally recognized as a strong, lightweight, flexible material that is 100% recyclable
Polypropylene (PP) is a thermoplastic “addition polymer” made from the combination of propylene monomers. This material has a high melting point that makes it good for hot-fill liquids. That also makes it great for certain applications that require a good chemical resistance.
Polyvinyl Chloride (PVC, Vinyl)
Because it is dependable and lightweight, flexible PVC helps packaging do its job to maintain the integrity of the products inside, including medicines. It is more brittle than many of the other films for packaging, but it is still a commonly used packaging option. It had its hay-day during the time of DVD and CDs.
