The protective film is widely used in the surface of metal products, coating metal products, plastic products, automobile products, electronic products, profile products and other products, mainly to protect the products from pollution, scratch, corrosion in the process of production, processing, transportation, storage and use, protect the original bright and clean surface, improve the quality of the original products, and improve competitiveness.

After the use of the protective film, the quality of the protective film can not meet the requirements, it is likely to be degummed and difficult to separate. As a purchaser, we should learn to identify protective film, select high-quality protective film and protect product quality.

1. The degumming phenomenon of the surface protective film is the most common on the profile surface. When the user tears the protective film off the profile surface after the installation and construction of the profile, the adhesive of the protective film does not stick to the protective film along with the tearing of the protective film, and remains on the profile surface. The adhesive treatment is very troublesome, so it needs personnel to scrape the glue off the profile. [protective film]

This phenomenon shows that the pressure glue used for the protective film does not meet the requirements and the viscosity is too high, which makes it difficult for the protective film to peel off on the product. In case of this problem, we can dip a clean cloth with alcohol and wipe the residual sensitive adhesive repeatedly with moderate strength. The degree of attention is too big, and the smoothness of the profile cannot be affected after wiping.

2. It is difficult to peel the protective film, and the protective film cannot be effectively peeled. The sensitive adhesive used for surface protective film products is not special sensitive adhesive, and the protective film produced by non special sensitive adhesive is very difficult to peel, which is also produced by some and irresponsible manufacturers. The other is that the material used for the protective film is soft, unable to bear the tension, and it breaks when peeling.

When choosing suitable products, we should consider the quality of glue, the material of protective film, the manufacturer of regular protective film and the regular channel.
