Plastic film
A plastic film is a thin continuous plastic material. Thicker plastic material is often called a "sheet". Plastic films have a wide variety of uses. These include: packaging, plastic bags, labels, building construction, landscaping, electrical fabrication, photographic film, film stock for movies, video tape, etc.
Materials
Almost all plastics can be formed into a thin film. Some of the primary ones are:
- Polyethylene – The most common plastic film is made of one of the types of polyethylene: low-density polyethylene, medium-density polyethylene, high-density polyethylene, or linear low-density polyethylene.
- Polypropylene – Polypropylene can be made a cast film.
- Polyester
- Nylon
- Polyvinyl chloride – film can be with or without a plasticizer
- Cellulose acetate - an early bioplastic
- Cellophane - made of regenerated cellulose
- A variety of bioplastics and biodegradable plastics are available.
- Semiembossed film – Semiembossed film can be used as a liner to the calendered rubber to keep the properties of rubber and also to prevent dust and other things from sticking to the rubber while calendering and during storage.[1]
