The protective film on the market is generally divided into three structures on two sides: the base layer and the adhesive layer. 1. The general process is to apply the glue evenly on the base material. Base layer Mixing layer of rubber particles and base material 2. Co-extrusion process, that is, mixing the rubber particles with the base material, there is no glue on the surface, but it has a certain adhesive force and will not produce residual glue.
The advantages of PE protective film:
The advantage of PE protective film is that the protected product will not be polluted, corroded, scratched, etc. during production, processing, transportation, storage and use, and will protect the original smooth and shiny surface of the product, thereby improving the quality of the product and the market. Competitiveness.
The requirements for the use of PE protective film are as follows:
1. Appropriate viscosity: easy to stick and easy to tear.
Second, the peeling force is stable: the change over time is small, that is, the smaller the increase in the peeling force, the better.
3. Good weather resistance: under the condition of sunlight exposure, the service life can be as long as half a year to one year.
Fourth, long storage period: stored in the warehouse for more than one year, no change in quality.
Five, no pollution, no corrosion: the adhesive is inert and will not chemically react with the surface of the material to be adhered.
6. Excellent mechanical properties: tensile strength, elastic modulus, elongation, etc. that meet user requirements.
