At present, single-material packaging such as PE / PE has attracted everyone's attention because of its feasibility in recycling. This article focuses on the difficult issues that need to be solved at present. First, the function of the functional fabric base material of each composite layer is mainly printing, barrier properties, heat resistance and so on. The base material of the primer mainly reflects the physical functions, including drop resistance and heat sealability. For two-layer composite film, one must be responsible for achieving printability and the other for physical properties such as heat sealability. The two functions must be combined to achieve the full functionality of the package. At present, most domestic equipment is designed
