The difference between PE stretch film and PVC stretch film
Stretch film can also be called stretch film or heat shrinkable film. PE stretch film first uses EVA as self-adhesive material, but its cost is high and tasteful. Later, PIB and VLDPE are used as self-adhesive material. Mainly LLDPE, including C4, C6, C8 and metallocene PE (MPE). PE stretch film: It has high tensile strength, tear resistance, and good self-adhesiveness, so it can wrap the object into a whole and prevent it from falling and collapsing during transportation. The film has excellent transparency. The wrapped object is beautiful and elegant, and can make the object waterproof, dustproof and damage-proof. PE stretch film is widely used in cargo pallet packaging, such as packaging in electronics, building materials, chemicals, metal products, auto parts, wire and cable, daily necessities, food, paper and other industries. It also has the characteristics of good buffer strength, puncture and tear resistance, thin thickness and good performance-price ratio. PVC stretch film: It is excellent in wrapping, binding and firmness for the packaged items, and at the same time, the self-adhesiveness of PVC stretch film is completed by electrostatic adsorption. Easy to operate, low shrinkage temperature, excellent shrinkage effect, transparent luster, large shrinkage rate, suitable for packaging special-shaped wire and cable products.
