Shrink film selection standards

In the packaging industry, shrink film is a material widely used to package and protect products. Shrink film can tightly wrap the product, providing protection against shock, moisture, dust, etc. At the same time, the film can be closely attached to the package through the heat shrink process, improving the appearance and safety of the product. However, it is very important to choose the right shrink film. The following are the standards for shrink film selection:

Material and performance: The material and performance of shrink film have a crucial impact on its use effect. Common shrink film materials include PVC, POF and PE. Among them, shrink film made of PVC has good toughness and tensile strength, suitable for packaging heavier products; shrink film made of POF has high transparency and heat shrinkage performance, suitable for packaging food, medicine and other products; shrink film made of PE has good toughness and waterproof performance, suitable for packaging lighter products. Consumers should choose the appropriate material and performance according to their needs.

Thickness and specifications: The thickness and specifications of the shrink film are also factors that need to be considered. Generally speaking, thicker shrink films have better protection effects, but the price is also relatively high. In terms of specifications, the appropriate specifications should be selected according to the size and shape of the product to ensure that the shrink film can completely wrap the product without wasting material.
