Protective film performance and use requirements

The continuous development of the society and the progress of mankind, its people’s requirements for the quality of life are constantly improving, and its various new things are constantly emerging. It is this kind of seemingly ordinary life that has brought great convenience to us. In traditional packaging, the amount used by our food industry and medical industry is very large. Past use of packaging is a very serious environmental pollution.

Protective film performance requirements

1. The protective film is inert to the surface of the material being protected.

2. When the protective film is used, the material to be protected will have good adhesion properties to some extent. During the handling and processing of the material, the protective film will not warp or fall off.

3. The protective film has good weather resistance and stability of holding strength to a certain extent. After a few days or a long time, the peeling force does not increase significantly, and it is easy to peel off. When it is removed, there is no residue on the protected surface. The glue remains, no pictures.

4. Low crystal point.

 Protective film requirements

1. Suitable for stickiness: easy to paste and easy to tear.

2. The peeling force is stable, and its change is small when it is operated, that is, the smaller the peeling force rises, the better.

3. Weather resistance is good, under sunlight exposure conditions, the use period of up to six months to one year.

4. Long storage period, more than one year in the warehouse, no change in quality.

5. No pollution, no corrosion, the adhesive is inert and does not react chemically with the surface of the adhered material.

6. Excellent mechanical properties, in line with user requirements of tensile strength, elastic modulus, elongation and so on.
