The blue protective film of aluminum plate is produced by adding blue pigment to the original film in the process of blowing the transparent plastic rice, and then is produced by coating technology, applying oily glue or water-based glue. Generally divided into two types, one is water gel PE blue protective film, and the other is oil gel PE blue protective film. The blue PE protective film inherits the performance of the PE protective film. The blue PE protective film is made of a special polyethylene (PE) plastic film. According to the density, it is divided into high-density polyethylene protective film, medium-density polyethylene and low. Density polyethylene. The blue protective film is currently the most common protective film on the market.
The biggest feature of the aluminum blue protective film is blue, which is determined by the market and user preferences. In the long-term use of protective film, in the case of some special products, the blue protective film is much better than the transparent protective film, and is easy to identify. After some products are attached with a transparent protective film, it is impossible to distinguish where the film is located, which leads to the difficulty of the worker to open the transparent protective film and reduce the production efficiency.
Another feature of the aluminum blue protective film is that it can cover the flaws of the product and prevent the product from affecting sales due to defects. At the same time, the blue pet protective film mainly uses blue polyester film as the substrate. The color of the product is easy to recognize. It is a common transparent protective film in life. Its thickness is generally between 50um-125um, and the viscosity is also low-viscosity. Sticky and high viscosity. Mainly anti-wear, anti-scratch, dustproof, with high temperature resistance, no residue, good adhesion, scratch resistance, high gloss, good stiffness, good weather resistance (high temperature / high humidity / solvent), etc. characteristic
