In the 21st century with advanced technology, machines can replace people in work, which not only improves production efficiency, but also reduces some processes in the production process. The use of PE protective film is more and more widespread. When producing PE protective film, manufacturers need to continuously improve the advantages and service life of the product. We can see that the quality of some PE protective films is not very good on the market. At this time, we need To distinguish the purchase, how to distinguish the quality of the PE protective film?

In fact, the quality of the PE protective film is not difficult to distinguish. First, you can observe the crystal points on the surface. The fewer crystal points, the higher the manufacturing level of the PE protective film. The product quality is good. In addition to the surface quality, there are Intrinsic performance is also the key to identifying quality.

Adhesion is one of the characteristics that distinguish the quality of PE protective film. It will not warp or fall off during use. The adhesive of quality protective film is inert and will not react with the product surface. PE protective film of good quality has good weather resistance and sticking stability, and it can be easily removed even after long-term use, and will not leave residual glue on the surface, without leaving a shadow.

In addition, elongation, tensile strength, etc. are all key factors to measure the quality of PE protective film. The latter must consider economic issues and try to reduce costs while ensuring the smooth production of products.
