Stretch film can also be called PE stretch wrap film. The principle of the stretch film is to wrap the items tightly together with the help of the film's super strong wrapping force and retraction, and to fix them into a unit to prevent them from falling off. Even in an unfavorable environment, the products will not be loose or separated, and there are no sharp edges and stickiness to avoid damage.
PE stretch wrap film is widely used in the centralized packaging of various goods. It has the advantages of high tensile strength, large elongation, good self-adhesion and high transparency. It can be used for manual wrapping film, machine wrapping film, etc.
The characteristics of PE stretch wrap film are as follows:
Primary protection: Primary protection provides surface protection for the product, forming a very light and protective appearance around the product, thereby achieving the purpose of dustproof, oilproof, moisture-proof and waterproof. It is important that the wrapping film packaging makes the packaged items evenly stressed, and avoids damage to the items caused by uneven stress, which is impossible with traditional packaging methods (packaging such as bundling, packaging, and tape).
Compression fixation: With the help of the retraction force of the wrapping film after stretching, the product is wrapped and packaged to form a compact, space-saving unit as a whole, so that the product pallets are tightly wrapped together, which can effectively prevent the mutual dislocation and movement of the products during transportation. At the same time, the adjustable stretching force can make hard products close together and make soft products compact.
Cost saving: Using wrapping film for product packaging effectively reduces the cost of use. The use of wrapping film is about 15% of the original box packaging, about 35% of heat shrink film, and about 50% of carton packaging. At the same time, it can reduce the labor intensity of workers and improve packaging efficiency and packaging grade.
