Suzhou PE protective film PE, full name of Polyethylene, is the most simple structure of the polymer compounds, the world's most widely used polymer materials. PE protective film in a special polyethylene (PE) plastic film to the substrate, depending on the density of the protective film is divided into high-density polyethylene, medium density polyethylene and low density polyethylene. PE protective film of the biggest advantages is being protected products in the production, processing, transportation, storage and use of the process from contamination, corrosion, scratches, protect the original smooth glossy surface, thereby improving the quality and competitiveness of products The main purposes: 1. Hardware industry: computer case, galvanized plate stamping, aluminum, stainless steel, titanium plates, steel plates, glass, solar panels and so on. 2. photovoltaic industry: LCD liquid crystal display, backlight, EL, membrane switch, cell phone screen and so on. 3. plastic industry: ABS, PP injection products, PVC sheet, acrylic sheet, instrument, plastic lenses, painting surface protection, and so on. The printing industry: PVC, PC boards, aluminum, film and other printed nameplates surface protection and so on. 5. wire and cable industry: shaft mounted copper, semi-finished products, finished products and rolling protection, which can effectively prevent dust pollution, anti-oxidation, anti-soiling effect. Intelligent packaging materials. 4.0 With the advent of the industrial era, the development and application of intelligent packaging, food packaging will become the new trends, with a huge market potential. It is expected that future smart packaging food contain more complex, remote-readable non-visual information. Safety labels and radio frequency identification (RFID) tags are at the beginning of an electronic tag, in addition to product identification information, date of production, price, electronic tags can be used as time - temperature, leakage, or freshness indicator.
