Stretch film, also known as stretch film, heat shrink film, the principle is to use the film’s super winding force and retractability to compact and fixedly bundle the product into a unit, and the product will not be loose even in unfavorable environments. With separation, degrees and without sharp edges and stickiness, so as not to cause damage. Various forms of use in life:
Hermetic packaging: This type of packaging is similar to shrink wrap, 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 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 is suitable for use with a film thickness of 17-35μm Manual packaging: This type of packaging is the simplest type of wrapping film packaging. The film is mounted 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 μm;
Stretch film wrapping machine packaging: This is the most common and extensive form of mechanical packaging. The tray rotates or the film rotates around the tray, and the film is fixed on the bracket 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; Horizontal mechanical packaging: different from other packaging, the film revolves around the article, suitable for long cargo packaging, such as carpets, boards, fiberboards, special-shaped materials, etc.; Paper tube packaging: This is one of the newest uses of stretch film, which is better than the old-fashioned paper tube packaging. The suitable film thickness is 30～120μm;
Packaging of small items: This is the latest packaging form of stretch film, which can not only reduce material consumption, but also reduce the storage space of pallets. In foreign countries, this packaging was first introduced in 1984, and only one year later, it appeared on the market. With many such packages, this package format has huge potential. Suitable for film thickness of 15 ~ 30μm;
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.
Stretching form of pallet mechanism packaging: the packaging of stretch film must be stretched, and the stretching form of pallet mechanical packaging includes direct stretching and pre-stretching.
