Multi layer co extrusion barrier film is generally produced using a multi-layer co extrusion blow molding process or casting process as a film forming technology. Multi layer co extrusion has excellent barrier performance, mechanical properties, tensile forming performance, and heat sealing performance, and does not require additional compounding during the processing, nor does it involve printing ink, adhesive, and additive residue. Therefore, it is a relatively green, environmentally friendly, and cost-effective food packaging technology process.

seven、nine、Eleven layer coextrusion tensile film is a kind of multilayer coextrusion tensile film with high barrier property commonly used in daily life. It is precisely to melt and extrude resin raw materials with different functions, such as PA/PE/PP/EVOH, etc., through their respective flow channels to join in the same the first mock examination head, and then to join together through the blow molding cooling method.

seven、nine、Eleven layer co extruded stretch film, as a type of multi-layer co extruded stretch film, can achieve different functions such as high temperature resistance, low temperature resistance, oil resistance, quality preservation, fragrance preservation, etc. by slightly changing the structural combination based on its material selection; Multi layer co extruded stretch film packaging products made by combining different material structures can be widely used in multiple food packaging fields
