What is the production process of PVC film?

The production process of PVC film is unpacking, inspection, sieving, formula-mixing → granulation → extrusion of thick film → air cooling → hot water bath boiling water heating → horizontal inflation of shaping cylinder → bubble quenching by film clamping roller → winding into heat shrinkable film. The production process of PVC is not complicated. The common production line is generally composed of a roller press, a printing machine, a back coating machine and a cutting machine. The film with a thickness of only 0.3mm to 0.7mm is mainly produced through the direct stirring of the roller press, the rotation of the roller and the high-temperature rolling. At the same time of production, the front surface of the film is printed with color by the printing machine, and a layer of back coating is attached to the back surface on the back surface of the film. Don't underestimate this layer

Barrier packaging substrate film

Barrier packaging substrate film

[1] Aluminum foil usually refers to aluminum-plastic composite vacuum packaging bags, used to package food, pharmaceutical industrial products, daily necessities, etc. [2] aluminum plating is through the vacuum aluminum plating process will be high purity in the aluminum wire at high temperature (1100~1200 ℃) evaporation into a gaseous state, after the plastic film through the vacuum evaporation chamber, the gaseous aluminum atoms precipitated to the plastic film surface and the formation of bright metal color film. [3]EHA high barrier film is a high barrier film co-extruded biaxially stretched by nylon 6 slices and EVOH slices. Based on the world's most advanced magnetic drive linear motor synchronous biaxial stretching equipment, it is independently developed by Changsu
