The principle of wrapping the film on the object
This package is similar to a shrink-wrap machine package in which a wrap-around film machine wraps the objects on the tray all around, and then the two hot grippers heat seal the films at both ends. This is the earliest form of use, and thus the development of more packaging forms of full width packaging. This packaging requires that the wrapping film machine is wide enough to cover the tray, the shape of the tray is regular, so it has its use, suitable for film thickness of 17 ~ 35μm hand-wrapped This package is the simplest of the packages. The film is mounted on a rack or held by hand, and the tray is rotated or wound around the film machine. It is mainly used for repackaging after the packaged tray is damaged, and for ordinary tray packaging.
Stretch film machine
The packaging speed is slow, and the suitable film thickness is 15-20 μm; the tray mechanical packaging is the most common and widest form of mechanical packaging, which is rotated by the tray or the film is rotated around the tray, and the wrapping film machine is fixed on the bracket to move up and down. . This packaging capacity is very large, about 15 to 18 plates per hour. The suitable wrapping film machine is about 15~25μm thick; the horizontal mechanical packaging is different from other packagings, and is rotated by the wrapping film machine, which is suitable for long cargo packaging, such as carpet, board, fiberboard, profiled materials, and the like.
The main function of the stretch film machine is to stabilize, cover and protect the product. It is widely used in the whole collection packaging of wine, cans, mineral water, various beverages, cloth and other products. The product has good flexibility, strong impact resistance, tear resistance, not easy to break, not afraid of tide, shrinkage rate. Big.
