Characteristics of shrinkage film perforation

Characteristics of shrinkage film perforation:

Shrinkage film has no puncture holes. This situation is mainly aimed at the case of shrink film packaging. When the user's products need to be packaged, the surface of the shrink film is changed to puncture some small holes, so that the gas in the film can be emitted through the small holes when shrinking, otherwise the gas is all in the film, and the film will bulge.

Shrinkage film is widely used in the outer packaging of medical medicine boxes, cultural and sports supplies, craft gifts, printed matter, hardware and plastic products, plaster lines, crispy peppers, telephones and other products. It can not only achieve the functions of moistureproof, dustproof, touch-proof and transparent display of goods, but also increase the attractiveness of products. It can also be used to replace all kinds of cartons, which not only saves packaging costs, but also conforms to the packaging trend.

Shrinkage film can be processed into special-shaped bags such as flat pocket, barrel section, arc-shaped bag, trapezoidal bag and three-dimensional bag.
