What are the characteristics of composite packaging coil, you know?

Commonly used composite packaging coil is made from polyethylene film more, non-toxic, the film can be used for holding food. There is also a film for PVC, polyvinyl chloride (PVC) itself is non-toxic, but according to film in place of the additive is often harmful substances to human body, has a certain toxicity. So this kind of film and made of the thin film bag should not be used for holding food. Composite packaging coil main features: 1, composite packaging coil density is small, but the intensity is larger, so the packing rate is quite high. 2, the chemical resistance of composite packaging coil is good, both in the acid alkali environment, such as long-term placement, oxidation phenomenon will not occur. 3, the use of composite packaging coil plastic molding easily, so the energy consumption is lower. 4, transparent, good performance, so the color more easily. 5, light is high, and has good resistance to impact. 6, insulation performance is good, and the processing cost is low.
