Food composite flexible packaging is composed of two or more layers of food grade raw materials composite material.
Flexible packaging of plastic film commonly used film substrate is generally the main plastic film, because it has a good thermoplastic, usually using extrusion casting, blow molding, biaxial stretching and other methods of processing. Common plastic films are:
①(PVE, HDPE, LLDPE, VLDPE, MPE), polypropylene film (CPP, BOPP), polyvinyl chloride (PVC), polyester (PET), polyamide film (PA) , Polystyrene film (PS), cellulose plastic film (PT);
② high-performance plastic film: polycarbonate film (PC), polyurethane film (PU);
③ high barrier plastic film: polycarbonate film (PC), polyurethane film (PU).
Usually we are based on the characteristics of the product and performance with different materials in order to achieve the best performance of its packaging.
