The use and characteristics of PE stretch film
Stretch film can also be called PE stretch wrap film. The principle of stretch film is to use the super strong winding force and retractability of the film to wrap the items in a flexible and tight way, and fix them into a unit to prevent them from falling apart. Even in unfavorable environments, the products will not loosen or separate. And there are no sharp edges and sticky to avoid damage. PE stretch wrapping film is widely used in centralized packaging of various goods, and has the advantages of high tensile strength, high elongation, good self-adhesiveness, and high transparency. It can be used for manual stretching film, and can also be used for machine stretching film and so on. The characteristics of PE stretch wrap film are as follows: Primary protection: primary protection provides surface protection of the product, forming a very light and protective appearance around the product, so as to achieve the purpose of dustproof, oilproof, moistureproof, waterproof and so on. The important thing is that the stretch film packaging can make the packaged items evenly stressed, and avoiding damage to the items due to uneven force is something that traditional packaging methods (bundling, packing, tape, etc.) cannot do. Compression fixity: After stretching with the help of stretch film The retracting force wraps the product to form a compact unit that does not take up space, so that the pallets of the product are tightly wrapped together, which can effectively prevent the mutual dislocation and movement of the product during transportation, and at the same time, the adjustable Tensile force can make hard products stick tightly and soft products shrink. Cost saving: The use of stretch film for product packaging can effectively reduce the cost of use. The use of stretch film is about 15% of the original box packaging, about 35% of the heat shrinkable film, and about 50% of the carton packaging. At the same time, it can reduce the labor intensity of workers, improve packaging efficiency and packaging grades.
