Low-density polyethylene film (LDPE) low density polyethylene film commonly used blown and cast into two processes. Cast polyethylene film thickness uniformity chemical resistance of plastic film, but because of higher prices, lower costs, so most widely used. LDPE film is a translucent, glossy, soft texture of the film, has excellent chemical stability, heat sealing, water resistance and moisture resistance, resistance to freezing, can be boiled. Its main drawback is the poor oxygen barrier properties, commonly used in flexible packaging material inner film, and is currently the most widely used, the largest amount of a plastic packaging film plastic film, about the consumption of plastic packaging film 40 % the above. Since polyethylene molecules contain polar groups, and high crystallinity, low surface free energy, so high temperature and low temperature plastic film, poor printing performance of the film, inks and adhesives to poor adhesion, so and prior to printing the need for complex surface treatments. Polyester film is a colorless, transparent, moisture, airtight, flexible, high strength, acid ester oils and solvents are not afraid of high temperature materials, electric discharge treatment, the surface of the ink has a relatively good fastness . For packaging and composite materials. Polypropylene film has good gloss and excellent transparency, heat resistance to acids, solvents, abrasion, tear-resistant, breathable, not less than 160 ℃ when heat-sealed.
