What is Protective Film Used for?

PE protective film with special polyethylene (PE) plastic film as the substrate, a cross-linked acrylic resin as an adhesive, and then processed by several special additives. The biggest advantage of PE protective film is that the protected products are not polluted, corroded, scratched during production, transportation, storage and use, and the original bright and shiny surface is protected, thus improving the quality of products and market competitiveness.

PE protective film application areas

PE protective film is often used in stainless steel plate, aluminum plate, aluminum alloy profile, plastic steel profile and doors and windows, aluminum plastic plate, fluorine carbon plate, mirror plate, sandwich color steel plate, fireproof board, veneer plate, plexiglass plate, PS, PE, PVC plate sunshine plate (polycarbonate plate), security doors, signs, coated glass, high-grade furniture, high-grade crafts, electrical cabinets, computer shells, automotive lamps, flooring, household appliances shell PE protective film is used to protect the surface of products in various fields, such as instrumentation, etc.

PE Protective Film     

Aluminum sheet protection film has stable viscosity, easy to tear and stick, easy to use, and does not leave residual glue. The product is mainly used for surface protection of various metal plates (sheets), such as polished surface, frosted surface and brushed surface of aluminum alloy of various specifications; surface protection of aluminum alloy oxidized polished and oxidized colored surface, etc. in transportation, storage and mold processing.

PE aluminum profile protective film has the characteristics of strong anti-aging ability and high adhesive force.

PE protective film for field construction is made of oil-based adhesive, with good initial adhesion, easy to stick construction, high water-expanding ability of adhesive, strong adaptability in bad weather conditions, and lower price than PVC protective film. 

 Protective Film for Aluminium Profiles and Plates

PE aluminum protective film has the characteristic of not polluting the surface of aluminum under the environment of long years of storage. There are types of printing, transparent, milk white printing, black and white film printing, etc. For different adhesion requirements from imitation mirror steel aluminum to electrophoresis aluminum and anodic coloring aluminum, powder spraying aluminum, fluorocarbon spraying aluminum, etc..

What are the main factors that the quality of PE protective film depends on?

PET protective film is used a lot, PET protective film is adhesive, electronics, die-cutting, printing and other industries commonly used a release material, what are the factors that affect PET protective film? Do you understand all? China's market demand is huge, but the domestic PET protective film due to the substrate and silicon coating technology backward, high-end products are still dependent on imports. PET protective film manufacturers talk about the following factors that affect the quality of PET protective film:

First, the substrate: PET release film is silicon release agent coated on the surface of the PET film, the quality of the substrate directly affects its performance. Domestic PET film substrate in the thickness control and heat shrinkage lags behind foreign countries.

Second, the residual adhesion rate: residual adhesion rate, refers to the force of the release paper after the first peel, the second peel, the data obtained after calculation, mainly reflecting the effect of silicone oil curing.

Third, the peel force: the size of the peel force directly affects the performance of PET release film, the general industry standard peel force tolerance range is ± 15%.

Fourth, the processing environment: with the increasing progress of various products, quality and technical improvements, the cleanliness of PET protective film requirements are becoming increasingly stringent, especially in the electronic film cutting industry.
