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, video tape, etc.


Almost all plastics can be formed into a thin film. Some of the primary ones are:


A tube of extruded film being blown to expand

Plastic films are usually thermoplastics and are formed by melting for forming the film.

  • Cast – Plastics extrusion can cast film which is cooled or quenched then wound up on a roll.
  • Extruded film can be stretched, thinned, or oriented in one or two directions. Blown or tubular process forces air into an extruded ring to expand the film. Flat tenter lines stretch the extruded film before annealing.
  • Calender rolls can be used to form film from hot polymers
  • Solution deposition is another film forming process.
  • Skiving is
