What is coextruded multilayer films for packaging "DIFAREN"?
Coextruded multi-layer film is produced by a compound molding technique that simultaneously extrudes thermoplastic resin with multiple extruders and passes that through a single die to build up layers of melted resin both on the inside and outside of a film. DIC was the first manufacturer in Japan to produce and sell coextruded multi-layer films by the T-die process in the 1970s.

Multi-layer Film Characteristics
Extremely thin layers of resin that cannot be made into a film by themselves can be layered by coextrusion. In this manner, a number of functions can be combined in a single film such as heat resistance, heat sealing capabilities, rigidity, flexibility, cold resistance, and easy-peel capabilities.
