1. Sealed packaging This type of packaging is similar to shrink wrap, where 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 form of wrapping film, and more packaging forms have been developed from this 2. 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 with a film thickness of 17-35μm 3. Manual packaging This kind of packaging is the simplest kind of wrapping film packaging, the film is loaded on a rack or by hand, and the film is rotated by the tray or the film is rotated around the tray. Mainly used for repackaging after the packaged pallet is damaged, and ordinary pallet packaging. This kind of packaging speed is slow, and the suitable film thickness is 15-20 μm; 4. Stretch film wrapping machine packaging This is one of the most common and widespread forms of mechanical packaging. The tray rotates or the film rotates around the tray. The film is fixed on the support and can move up and down. This packing capacity is very large, about 15 to 18 trays per hour. The suitable film thickness is about 15-25μm; 5. Horizontal mechanical packaging Different from other packaging, the film revolves around the item, which is suitable for the packaging of long goods, such as carpets, boards, fiberboards, special-shaped materials, etc.; 6. Packaging of paper tube It's one of the newest uses for stretch wrap, and it's better than the old-fashioned paper tube wraps. The suitable film thickness is 30～120μm; 7. Packaging of small items This is the latest packaging form of wrapping film, which can not only reduce material consumption, but also reduce the storage space of pallets. In foreign countries, this kind of packaging was first introduced in 1984. Just one year later, many such packaging appeared on the market. This packaging format has huge potential. Suitable for film thickness of 15 ~ 30μm; 8. Packaging of pipes and cables This is an example of the application of stretch film in a special field. The packaging equipment is installed at the end of the production line, and the fully automatic stretch film can not only replace the tape to bind the material, but also play a protective role. The applicable thickness is 15 to 30 μm. 9. Stretch form of pallet mechanism packaging The packaging of stretch film must be stretched, and the stretching forms of pallet mechanical packaging include direct stretching and pre-stretching. There are two types of pre-stretching, one is roller pre-stretching and the other is electric stretching. The above are the various forms of use of the wrapping film that Xiaobian shared with you today. If you want to know more about the wrapping film, please call for consultation! !
