PP EVOH PP film roll for Thermoformed tray

A PP/EVOH/PP film roll is a type of multilayer film used for thermoforming trays. The film is made up of three layers: a polypropylene (PP) layer on the outside, an ethylene vinyl alcohol (EVOH) layer in the middle, and another PP layer on the inside.

The PP layers provide strength and stability to the film, making it suitable for thermoforming applications. Thermoforming is a process in which the film is heated and then molded into the desired shape of the tray.

The EVOH layer acts as a barrier against oxygen and other gases, making the film ideal for packaging applications where the preservation of the contents is crucial. It helps to extend the shelf life of the packaged products by preventing the ingress of oxygen and the escape of aroma and flavor.
