Functional Requirements And Special Process Of PE Protective Film
In terms of function, the PE protective film is mainly to put a layer of film on the physical objects we need to protect. Now there are functional protective films such as AR anti-reflective film, AG frosted anti-reflective film, mobile phone mirror film, anti-peeping film, and high-definition anti-scratch film. We mainly understand the protective film used to protect the aluminum plate.
The PE protective film is basically made of pet material when used, and has a three-layer anti-scratch and anti-electromagnetic radiation structure to a certain extent. The thickness of the protective film is about 0.25mm. Anti-reflective, anti-electromagnetic radiation, effectively filter ultraviolet rays. Electrostatic adsorption technology, no glue can be pasted many times. High abrasion resistance, excellent scratch resistance, durable. It can effectively protect the surface of the aluminum plate from scratches.
Performance requirements of PE protective film
- The protective film is inert to the surface of the protected material.
- PE protective film has good adhesion to the protected material, and the protective film will not warp or fall off during material handling and processing.
- The protective film has good weather resistance and adhesion stability.And the peeling force does not increase significantly after several days or a long period of time.And it’s easy to remove. When peeled off, no residual glue remains on the protected surface and no image is left.
- Low crystal point. The peeling force of the PE protective film is stable. And the change is small after the process,the smaller the peeling force rises, the better.
- Good weather resistance: Under the condition of sunlight exposure, the service life is as long as half a year to one year. And the storage period is long: the quality does not change after being stored in the warehouse for more than one year
