What is the PE heat shrinkable film? What is the use?
The production of PE heat shrinkable film generally adopts extrusion blow molding or extrusion softening method to produce thick film, and then stretches longitudinally and transversely at a high elastic state temperature above the softening temperature and below the melting temperature, or stretches only in one direction without stretching in the other direction. The former is called biaxially stretched shrink film, and the latter is called unidirectional shrinkage film. When in use, when the temperature is higher than or close to the stretching temperature, the goods are packed with reliable shrinking force.
