PE shrink film has the characteristics of high tensile strength, large elongation, good self-adhesiveness and high transparency. It can be used for hand-wound film or machine-wound film, and can be widely used in centralized packaging of various goods. The PE stretch film is mainly made of a mixture of several different grades of polyolefin resin. It has puncture resistance, high strength and high performance. It wraps the goods stacked on the pallet to make the package more stable and tidy. Strong waterproof effect, widely used in foreign trade, paper, plastics, building materials, food and pharmaceutical industries. The following China Plastics Network - Jiuzhi Plastics Network tells you about the four characteristics of PE shrink film, as follows:
Unitization
This is one of the biggest features of shrink wrap packaging. With the superior winding force and retracting property of the film, the product is compactly and fixedly bundled into one unit, so that the scattered small pieces become a whole, and the product does not have any looseness and separation even under unfavorable environment, and there is no sharpness. The edges and stickiness are so as not to cause unnecessary damage.
2. Primary protection
Primary protection provides surface protection of the product, forming a very light, protective appearance around the product to achieve dust, oil, water and security. It is especially important that the wrapping film package makes the packaged articles evenly stressed, and avoids damage caused by uneven force. This is not the case with traditional packaging methods (bundling, packaging, tape, etc.).
3. Compression fixation
The product is wrapped by the retractive force of the stretched film to form a compact, space-saving unit, so that the trays of the product are tightly wrapped together, which can effectively prevent the products from being misaligned during transportation. Mobility, while the adjustable stretch force can make the hard product close, making the soft product tight, especially in the tobacco industry and the textile industry.
4. Cost saving
The use of the wrapping film for product packaging can effectively reduce the cost of use. The winding film is only 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 grade.
