But why use shrink wrap?

The product after shrink wrapping can fully display the appearance of the product, improve the displayability of the product, and increase the aesthetics and sense of value. At the same time, the wrapped products can be sealed, moisture-proof, pollution-proof, and protect the products from external shocks, and have a certain buffering property. Especially when the product is fragile, it can prevent scattering after being broken.

The principle of shrink wrapping:

When the heat shrinkable film is heated at high temperature, the irregular arrangement of atoms changes drastically. Under the irradiation of infrared light, the plastic molecules move again and the arrangement changes, so that the atoms can be re-arranged by heating. The arrangement leads to a great reduction in the area of the product. In this way, it can more closely fit the finished product to be packaged and processed by the manufacturer, and can quickly wrap a layer of thermal film on the product.


The main equipment used in shrink wrapping is a shrink wrap machine. It belongs to automatic packaging equipment. It is heated by radiating optical fibers such as infrared rays, which can quickly reach a high temperature for preheating and save energy. It can quickly adjust the temperature through electronic stepless, no matter how the temperature needs to be changed during production, it can quickly adjust the temperature and speed up the operation time of high temperature preheating. It can more effectively meet the practical application of production and life. And it can be applied to regular and irregular products, and has a wide range of applications.
