How to distinguish PE electrostatic film, wrapping film and ordinary protective film?
Different from electrostatic film, the first look at the material, the general PE material is the main material of the electrostatic film, PE is softer than other materials. PE electrostatic film is generally used for food-grade and other environmentally-friendly requirements. The second look is sticky: the electrostatic film is electrostatically adsorbed, there is no glue, you touch it by hand, the adhesive is generally an electrostatic film. The third try, the electrostatic film is attached to the smooth glass, relying on its own electrostatic adsorption It is automatically sucked up. The electrostatic film is self-adhesive, while the PVC protective film is sticky.
The electrostatic protective film is a two-layer co-extruded protective film produced by a special production process, and the product has excellent stability under high temperature conditions. Because it does not use any adhesive, it can be used in any environment without residual impurities on the surface of the product, which is more environmentally friendly and reliable. It does not produce or volatilize any toxic gases and environmentally harmful substances during or after use, and is widely used in various industrial fields. It has obvious effects on product surface protection, effectively reducing the production of defective products, improving process stability and enhancing product value. The pvc electrostatic protective film uses static electricity to attach the plastic film to other items to be protected by the glass, thereby achieving the purpose of protecting the product. Pvc electrostatic protection film is suitable for products requiring electrostatic film protection. It is ultra-thin, strong, transparent, self-adhesive, good transparency, small water grain and less crystal point. High static resistance, good electrostatic effect, low temperature resistance, etc.
Stretch film is a kind of packaging material used for logistics packaging: it has stretching effect, is easy to use, and is not easy to fall off. The electrostatic film is a printing material, the stretching degree is small, and the cost is much higher than that of the wrapping film, but it can be used for surface protection packaging, such as jewelry, watch dial and the like. The electrostatic film is a kind of non-adhesive film. It is protected by electrostatic adsorption of the product itself. It is generally used for the surface sensitive to adhesive or glue residue. It is mostly used for glass, lens, high gloss plastic surface, acrylic. Wait for a very smooth surface. Looking at the appearance, each film is similar, only through professional ability to analyze.
