Thin layers with a thickness of 0.3 to 0.2 mm, which are composed of natural, synthetic and composite polymers with high flexibility due to a layer of continuous polymeric material, are called polymer films, although a thicker type of it is also called a sheet (Sheet) is called.
Polyolefins are the most common polymers in the production of polymer films and the major polymers used in this industry include polyethylene, polypropylene, polyvinyl chloride (pvc), polystyrene, polyethylene terephthalate (PET), poly Amide is ethyl vinyl chloride (EVA) and polyvinylidene chloride (PVDC).
Plastic films mentioned a wide variety of applications, including product packaging, plastic bags, labels, construction, photography, video, and so on.
Attention to points such as permeability to water vapor and oxygen, strength and tensile changes, maximum user temperature, cost, processability are some of the things that are important in choosing the type of polymers used in polymer films.
