Introduction to the form of shrink film packaging

Heat shrinkable film is used for the sales and transportation of various products, and its main function is to stabilize, cover and protect the product. The shrink film must have high puncture resistance, good shrinkage and a certain shrinkage stress. During the shrinking process, the film cannot produce holes. Since shrink film is often used outdoors, it is necessary to add UV anti-ultraviolet agent. 1. Sealed packaging 　　 This type of packaging is similar to shortened 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 how the wrap film is used, and thus more packaging methods have been developed. 2. Full width packaging 　　 This type of packaging requires that the packaging film is wide enough to cover the tray, and the shape of the tray is regular, so it has its own use. The appropriate film thickness is 17-35μm. 3. Manual packaging 　　 This kind of packaging is a very simple type of packaging around the film machine. The film is mounted on a shelf or hand-held, transformed from a tray or revolved around the tray. It is mainly used for repackaging after the wrapped pallet is damaged, and popular pallet packaging. The packaging speed is slow, and the suitable film thickness is 15-20μm. 4. Stretch film packaging 　　 This is a fairly common mechanical packaging method. The film is fixed on the bracket and can be moved up and down by rotating the film or the film. This kind of packaging can be very large, about 15-18 trays per hour. The suitable film thickness is about 15-25 μm. 5. Horizontal mechanical packaging 　　 is different from other packaging. The film revolves around the item, which is suitable for long goods packaging, such as carpet, board, fiberboard, profiled material, etc. 6. Paper tube packaging　　This is one of the new uses of wrapping film, which is better than old paper tube packaging. The suitable film thickness is 30 to 120 μm. 7. Packaging of small items This is a new packaging method of shrink film, which can not only reduce data consumption, but also reduce the storage space of pallets. In foreign countries, this kind of packaging began to be introduced in 1984, and only one year later, it appeared on the market. With a lot of such packaging, this packaging method has great potential. The suitable film thickness is 15-30μm. 8. Packaging of tubes and cables　　 This is an example of the wrapping film machine used in the extraordinary field. The packaging equipment is installed at the end of the production line. The fully active stretch film can replace the tape to bind the materials and can also be used for maintenance. The combined thickness is 15-30μm.
