How long does the PE protective film last?

- Jan 08, 2020-

PE material is the simplest polymer organic compound, and it is the most widely used polymer material in the world today. PE protective film is based on a special polyethylene (PE) plastic film. It is divided into high-density polyethylene protective film, medium-density polyethylene and low-density polyethylene according to the density.

The biggest advantage of PE protective film is that the protected product is not contaminated, corroded, scratched during production, processing, transportation, storage and use, and protects the original smooth and shiny surface.

PET film is also known as high temperature polyester film. It has excellent physical properties, chemical properties, dimensional stability, transparency, and recyclability, and can be widely used in magnetic recording, photosensitive materials, electronics, electrical insulation, industrial films, packaging decoration and other fields.

The protective film has good weather resistance and sticky stability. The peeling force does not increase significantly after a few days or a long period of time, and it is easy to peel off. When it is peeled off, there is no residual glue and no shadow on the protected surface. The PE protective film can be electrostatically adsorbed, which does not hurt the product surface. The electrostatic protective film can still be used after washing.

How long is the life of the PE protective film? This is where we need to remember when using the PE protective film. PE protective film is insoluble in any solvents at room temperature, but can be soluble in aliphatic hydrocarbons and aromatics at higher temperatures. Hydrocarbons and halogenated hydrocarbons. For example, LDPE can be dissolved in benzene at 60 ° C, HDPE can be dissolved in benzene above 80 ~ 90 ° C, and both can be dissolved in toluene, trichloroethylene, tetrahydronaphthalene, decahydronaphthalene, petroleum ether above 100 ° C Mineral oil and paraffin. The protective film will be deformed under high temperature, please use it with caution.
