There are many types of plastic film and their functions are varied. Anti-fog film has excellent anti-fog performance on both sides for high performance under every application; pearl film has excellent machinability, high tensile strength, stiffness and flatness; PE film has High optical clarity, gloss and seal strength; heat sealing film has excellent stiffness, superb opacity and whiteness. 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.
BOPP film, full name is biaxially oriented polypropylene film; DECRO has a proven track record of innovation and product development in the manufacturing of BOPP film. DECRO innovative products enjoy strong market share growth across the global film product markets, especially in the area of new technology films. 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. Skiving is used to scrape off a film from a solid core. Coextrusion involves extruding two or more layers of dissimilar polymers into a single film. Extrusion coating is used to form a film onto another film or substrate.
Plastic films are typically formed into rolls by roll slitting. Often additional coating or printing operations are also used. Films can be modified by physical vapor deposition to make metallised films. Films can be subjected to corona treatment or can have release agents applied as needed.
