What are the advantages of PE heat shrinkable film

The products manufactured by PE heat shrinkable film manufacturers can be used in many industries. What kind of characteristics does it have? Now let's follow the manufacturers to understand this knowledge introduction carefully? 　　 In fact, when we are manufacturing products, The thick film that needs to be extruded under 170-200 degrees Celsius is quenched in cooling water at 0-20 degrees Celsius, inflated at 20-50 degrees Celsius, and stretched horizontally. At the same time, the traction roller quickly pulls, stretches longitudinally, and after winding Become a PVC shrink film. Due to the narrow welding temperature range of PVC film, pulse and high-frequency heat sealing methods are generally used for heat sealing. It does not work with general acids and alkalis at room temperature and does not dissolve in organic solvents. But it is swellable and has poor oil resistance.　　It has good low temperature resistance and can meet the needs of food refrigeration and freezing. But it has a low melting point and poor high temperature resistance, so it cannot be cooked with food. High heat sealing performance and safety performance. The packaging adaptability of PE heat shrinkable film PE heat shrinkable film is the same as PP.
