What are the general properties of packaging film?

The packaging film is mainly extruded from a variety of different grades of resin, which has the advantages of puncture resistance and high performance. It is widely used in foreign trade, papermaking, hardware, plastic chemical, building materials, food, medicine and other industries. It is used for pallet packaging of goods to make the packaging more stable and tidy, and the waterproof effect is stronger.
1. Unification: This is one of the biggest characteristics of stretch film packaging. With the strong winding force and retraction of the film, the product is tightly bound into a unit, so that the scattered small pieces become a whole, even in unfavorable environments, the product does not have any looseness or separation, and the degree is not sharp. Edge and viscosity to avoid damage.
2. Basic protection: Basic protection provides products with surface protection to form a very light and protective outer around the product, so as to achieve the purpose of dust, oil, moisture, water, and anti-theft. It is particularly important that the packaging stretch film is uniformly stressed to the packaging material to avoid uneven stress damaging the product, which is not possible with traditional packaging (strapping, packaging, packaging tape, etc.).
3. Compression fixity: After the roll film is stretched, the product is wound and packaged with the help of contraction force to form a compact and space-saving whole, so that the product trays are tightly packed together, which can effectively prevent the product from dislocation and movement during transportation , Adjustable tension makes hard products fit tightly, soft products shrink, especially in the tobacco industry and textile industry, has a unique packaging effect.
4. Cost saving: The use of stretch film for product packaging can effectively reduce the cost of use. The use of stretch film only packs about 15% of the original box, heat shrinkable film about 35%, and carton packaging about 50%. At the same time, the labor intensity of workers can be reduced, and packaging efficiency and packaging quality can be improved.
