Improvement of PE heat shrinkable film technology

PE heat shrinkable film manufacturers point out that heat shrinkable film is a product that we often use in our lives. With the continuous maturity of technology, our production process is also constantly improving. The PE heat shrinkable film adopts a special process of biaxial stretching and three-layer fusion co-extrusion, usually by corona treatment, which is to improve the surface performance of the PE heat shrinkable film, improve the adaptability of printing and vacuum aluminum plating Cohesion of layers. However, the corona method has problems such as time, high temperature and high humidity, and the film tension is attenuated. Chemical coating is a good method, so it is favored by the printing industry and the aluminum plating industry. The heat shrinkable film produced must have puncture resistance, shrinkage and shrinkage stress. The continuous improvement of the process of heat shrinkable film has greatly improved its performance, so this is of great help in our use.
