The Principle Of Using Wrapping Film For Object Packaging

The wrapping film wraps around the tray to fully wrap the objects on the tray, and then two heat grippers heat seal the film at both ends together. This is the earliest form of use, and as a result, more packaging forms have been developed. Full-width packaging, this packaging requires the wrapping film to be wide enough to cover the tray, and the shape of the tray is regular, so it has its requirements for use, then in the object packaging process It can be divided into two types: manual packaging and pallet mechanical packaging. Then the editor of Shenzhen Qianghui Technology's stretch film manufacturer will explain the principle of stretch film in packaging in detail:

1. It is suitable for manual packaging with a thickness of 17-35μm. This kind of packaging is the simplest type of packaging. The wrapping film is mounted on a shelf or held by hand, and is rotated by the tray or the wrapping film is rotated around the tray. Mainly used for repackaging after the packaged pallet is damaged, and ordinary pallet packaging.

2. The suitable thickness of the wrapping film is 15-20μm; pallet mechanical packaging is the most common and extensive mechanical packaging form. This packing capacity is very large, about 15 to 18 trays per hour.

3. The suitable thickness of the wrapping film is about 15-25μm; the horizontal mechanical packaging is different from other packaging, and the wrapping film revolves around the article, which is suitable for the packaging of long goods, such as carpets, plates, fiberboards, special-shaped materials, etc.
