Plastic steel profile film selection of PE film (polyethylene film) and PET film (polyester film)

Plastic steel profile film selection PE film (polyethylene film) and PET film (polyester film) in the following aspects there are differences:

1. Material characteristics: PE film is a kind of polyethylene film, with soft, ductile and good ductility. PET film is a film made of polyester, which is relatively hard and has high tensile strength and wear resistance.
2. 2 transparency and gloss: PE film usually has good transparency, can keep the surface of the profile bright and transparent effect. PET film may have a high gloss on the surface, to add a certain appearance of the profile.
3. Scratch resistance: Due to the hardness of PET film, its surface is relatively scratch resistant, which can provide a certain degree of protection and reduce the occurrence of scratches on the profile surface. PE film is relatively soft and may offer less protection against large scratches.
4. Weather resistance: PET film usually has good weather resistance and can resist the influence of ultraviolet radiation, high temperature and humidity. The weatherability of PE film may be poor, and color change and deterioration may occur in long-term exposure to harsh environment.
5. Cost: In general, the cost of PE film is lower than that of PET film. PET membranes are expensive to manufacture, so they may be used in high-end applications or where appearance requirements are high.
   

According to the specific application requirements and expected results, the choice of PE film or PET film to protect the plastic steel profile will vary. Detailed consultation with relevant suppliers, manufacturers or professionals is recommended for more specific recommendations and customized solutions.
