The film is installed on a rack or held by hand, rotated by the tray or wound around the tray. It is mainly used for repackaging after the wrapped pallet is damaged, as well as ordinary pallet packaging. The packaging speed is slow, and the suitable film thickness is 15 ~ 20m；Packaging of paper cylinder.

This is one of the new uses of winding film, which is better than the old paper drum packaging. The suitable film thickness is 30 ~ 120m；Packaging of small items.This is a new packaging form of winding 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.

Only one year later, many such packaging appeared in the market. This packaging form has great potential. Suitable for film thickness of 15 ~ 30m；China clear scotch Bopp Tape Suppliers of pipes and cables.This is an example of the application of winding film in special fields. The packaging equipment is installed at the back of the production line. The fully automatic stretching film can not only replace the tape to bind the material, but also play a protective role.

We all know that different widths of PE stretch film have different uses, and it must have high puncture resistance, good shrinkage and certain shrinkage stress. Do you know what the useful width deviation is?In the relevant industry standards of stretch film, the useful width deviation of stretch film is not revised when the bag width is 700mm or less, and the deviation of the original standard + 15mm-10mm is retained.

If it is more than 700mm, the allowable deviation is + 20mm-10mm.In addition, why does it have more and more layers? It is understood that the film with many layers is only applicable to the tape casting and stretching film wrapped by the machine.
