Stretch film, shrink film, etc. have a protective effect on the product, while protecting the product, but also enhance the quality of the goods, because the stretch film around the product to form a very light maintenance appearance The primary maintenance provides the appearance maintenance of the product. In order to achieve the purpose of dust, oil, moisture, waterproof, anti-theft, especially important stretch film packaging to force evenly packaged goods, to prevent damage caused by uneven force on the goods, which is bundled, packaged, tape and other packaging can not Do it.
At present, the stretched film is widely used in different fields. The stretched film is produced by a three-layer coextrusion casting process, and the imported linear low-density polyethylene is the main raw material. The technical indicators of the products have reached the international advanced level, with the advantages of uniform film, good tensile properties, strong retractive force, high transparency, high tear strength, and self-adhesion at room temperature. The film thickness was arbitrarily cut from a width of 15 μm and a width of 50 μm from 5 cm to 100 cm. Viscous single-sided sticky and double-sided sticky. Widely used in building materials, chemicals, glass, ceramics, electronics, metal, auto parts, wire, paper, cans, daily necessities, food and other industries of the strapping packaging and various types of tray packaging, so as to achieve moisture, dust, reduce labor, improve efficiency And the effect of reducing costs.
The stretch film packaging forms a compact, space-free unit as a whole, and the product is wound and wrapped by the stretched film stretching force so that the product trays are tightly wrapped together and can effectively prevent transportation. During the process, products are misaligned and moved. Stretch film can be adjusted at the same time. The stretching force can make the hard products cling tightly, which makes the soft products shrink. Especially in the tobacco industry and the textile industry has a unique packaging effect. Can effectively reduce the cost of using stretch film packaging products. The stretched film is only about 15% of the original box, about 35% of the heat shrinkable film, and about 50% of the carton. At the same time, the labor intensity of workers can be reduced, and the packaging efficiency and packing grade can be improved.
