4: Finally hold scissors to cut the packing belt.
The packing belt is made of a mixture of PP and PET plastics. Main production process: plastic particle melting — pressure tape —- molding —- cooling —– winding —- packaging – storage packaging tape system using polypropylene through heating, melting, stretching, cooling produced by the network structure of packaging material, the basic parameters that affect the quality of packaging tape are tension, length, bending, elongation and so on. In the case of the same tension and other parameters, the longer the length, the lower the cost.
