Stretch Wrap suppliers 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 use of transparent PE stretch film, and more packaging forms have been developed from this Full-width packaging: This kind of packaging requires the film width to cover the tray, and the shape of the tray is regular, so it has it in use, suitable for film thickness of 17 ~ 35渭m Manual packaging: This type of packaging is the simplest type of wrapping film packaging. The film is loaded on a rack or by hand, and is rotated by a 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 渭m; 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 15-25渭m; 1. Horizontal mechanical packaging: different from other packaging, the film revolves around the item, suitable for long packaging of goods, such as carpets, boards, fiberboards, special-shaped materials, etc.; 2. Paper tube packaging: This is the latest use of pallet stretch film for packaging, which is better than the old-fashioned paper tube packaging with stretch film packaging. The suitable film thickness is 30锝?20渭m; 3. Packaging of small items: This is the latest packaging form of pallet stretch film for packaging, 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, only one year later, There are many such packagings on the market, and this packaging format has great potential.

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 渭m. Stretch form of pallet mechanism packaging 5. 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. 6. Direct stretching is to complete the stretching between the tray and the film. This method has a low stretch ratio (about 15% to 20%). If the stretch ratio exceeds 55% to 60%, it exceeds the original yield point of the film, the film width is reduced, and the puncture performance is also lost. easy to break. And at 60% stretch rate, the pulling force is still very large, and for light cargo, it is likely to deform the cargo.Stretch Wrap suppliers website:http://www.kaixiang-packaging.com/stretch-wrap/
