1. Sealed packaging
This kind of packaging is similar to shrink-wrap film packaging. The film wraps the tray around the tray, and then two thermal grippers heat seal the two ends of the film together. This is the earliest use of stretch film, and thus more packaging methods have been developed.
2. Craft packaging
This kind of packaging is the simplest kind of stretch film packaging. The film is mounted on a rack or hand-held, rolled by a tray or revolved around the tray. It is mainly used for de novo packaging after damaged pallets and general pallet packaging. This kind of packaging speed is slow, the suitable film thickness is 15-20μm;
3. Full width packaging
This kind of packaging requires the width of the film to cover the tray, and the shape of the tray is regular, so it has its own application. The film thickness of the suitable stretch film is 17-35μm.
4. Packaging of small items

The suitable film thickness is 15-30μm.
5. Stretch film wrapping machine packaging
This is one of the most common and extensive mechanical packaging methods. The tray rotates or the film rotates around the tray. The film is fixed on a bracket and can move up and down. This kind of packaging capacity is very large, about 15-18 trays per hour. The suitable film thickness is about 15-25 μm.
6. Horizontal mechanical packaging
Unlike other packaging, the film revolves around the article, which is suitable for packaging long goods, such as carpets, boards, fiberboards, and shaped materials.
7. Packaging of tubes and cables
This is a special application of wrap-around film. For example, after the packaging equipment is installed in the ziui of the production line, the fully active stretch film can replace the tape to bind the material and also have the maintenance effect. The applicable thickness is 15-30μm.
8. Paper tube packaging
This is one of the many uses of stretch film. Compared to the old-fashioned paper tube packaging, stretch film packaging is very good. The suitable film thickness is 30 to 120 μm.
