As an indispensable packaging material in daily work and life, stretch film has reached a wide range of applications. At present, it is widely used in chemical, building materials, food, electronic appliances and other industries. There is no need to perform heat shrinkage treatment in the packaging process, which is conducive to saving energy, reducing packaging costs, facilitating container transportation, and improving logistics efficiency.

1. Sealed packaging
​​
This kind of packaging is similar to shrink wrapping with wrapping film. The film wraps the tray around the tray, and then two heat grippers heat seal the film at both ends together. This is the earliest application method of stretch film, and thus more packaging methods have been developed.

2. Technical packaging
​​
This kind of packaging is the simplest type of stretch film packaging, the film is mounted on a rack or by hand, rolled by a tray or the film is rotated around the tray. It is mainly used for repackaging after the packaged pallet is damaged, and general pallet packaging. The packaging speed is slow, and the suitable film thickness is 15-20 μm;

3. Full width packaging
​​
This kind of packaging requires that the film width is enough to cover the tray, and the shape of the tray is regular, so it is suitable for use. The film thickness of the suitable stretch film is 17-35 μm.

4. Packaging of small items
​​
This is the latest packaging method of stretch film, which can not only reduce the material consumption, but also reduce the storage space of the tray
