The stretched film is self-adhesive and is a plastic film that is viscous and stretchable on one or both sides and wraps the packaged article, and the self-adhesive does not adhere to the surface of the packaged article, but only exists in the film and film. s surface. It has high tensile strength, large elongation, good self-adhesiveness and high transparency. Widely used in foreign trade, bottle making, paper, hardware, plastics, chemicals, building materials, agricultural products, food and other industries.

When the stretched film is used in the case of poor stretchability, it will easily lead to the dissatisfaction of the package, and the main effect on the wrapped package is greatly reduced, so when consumers buy the winding touch Note,
If you want to test the quality of its stretchability, firstly tear it away from the length of the stretched film, and then tear it away from the transverse direction. The tensile strength is strong, and the toughness is easy to tear. Broken, if it is too thin, the toughness will be greatly reduced, and the stretchability will not be good, so Xiaobian reminds you on this road: you can't blindly pursue the cheap when purchasing the stretch film.

Stretch film is often used in packaging paper, logistics, chemicals, plastic raw materials, building materials, food, glass and so on. Self-adhesive, high transparency items. High strength, high elastic force, suitable for any shape of goods. It is excellent in puncture resistance and tear resistance. It can avoid damage to items during bundling and has good anti-loose, rainproof, dustproof and anti-theft effects.
