Product Description

co-extrusion film is a kind of composite film which uses multi-layer coextrusion technology to combine a variety of substrates with different properties. It is a one-time molding, which can integrate the properties of various substrates, and can well meet the different functional requirements of flexible packaging.

The common structures of functional coextrusion film are:

PE / tie / PA / tie / PE (PA), with moderate barrier property and moderate strength;

PE / tie / EVOH / tie / PE has high barrier property and moderate strength;

PA / EVOH / PA / tie / PE, high barrier, high strength.

Outstanding advantages of functional coextrusion film The advantages of functional coextrusion film mainly include: high oxygen resistance, good moisture resistance, good aroma retention; Strong mechanical properties, high drop resistance, puncture resistance and tear resistance; High temperature resistance (121 ℃), low temperature resistance (- 40 ℃), grease resistance; Non toxic and tasteless, in line with the food and drug packaging health standards; Good heat sealing, flexibility and transparency.
