How to distinguish the quality of PE electrostatic film
There are already many manufacturers of domestic PE electrostatic film. Most PE electrostatic film production technology levels are similar. However, compared with foreign PE film manufacturers, there is still a certain gap in the domestic production technology level. In general, the quality of PE electrostatic film in Japan, Korea, and Taiwan is better than most domestic manufacturers. The quality of electrostatic membranes made by a few domestic manufacturers such as Yihong Packaging Materials Factory can also be compared with foreign ones. So how do we judge the quality of PE electrostatic film?
First, the PE electrostatic film has a low crystal point, and the fewer the crystal points, the higher the manufacturing level of the electrostatic film is. The quality of the electrostatic film is also better.
Secondly, the electrostatic film has good weather resistance and stability of holding force. After several days or a long time, the peeling force is not significantly increased, and it is easy to remove. When the film is removed, no residual glue remains on the surface to be protected, and no shadow is left.
The third electrostatic film has good adhesion to the material to be protected, and the protective film does not rise and fall during material handling and processing;
The fourth electrostatic film adhesive is inert and does not chemically react with the surface of the material to be bonded;
The fifth is in accordance with the user's requirements for tensile strength, modulus of elasticity, elongation, and the like.
The PE electrostatic film production technology of Yihong Packaging Materials Factory has developed very mature, and the electrostatic film for various purposes can meet the demand. Xiao Bian reminds everyone not to choose expensive, do not choose cheap, choose the right, choose the best price in the case of testing, in order to ensure the smooth production of the product, while reducing costs.
