3 & 5 & 7 Layers Coextrusion

3 & 5 & 7 Layers Coex-trusion

Co-extrusion bags are made by extruding multiple plastic layers at the same time (not laminated with glue). This creates a single, integrated film with excellent seal strength, puncture resistance, and barrier performance, widely used in vacuum food, frozen food, meat, medical, and industrial packaging.
