PE stretch film is an industrial film product, which has the characteristics of high tensile strength, large elongation, good self-adhesiveness and high transparency.
It is used for manual wrapping film, can also be used for machine wrapping film, and can be widely used in centralized packaging of various goods.
1. Sealed package
This package is similar to a shrink wrap package in which the film wraps around the tray and the two hot grips heat seal the film at both ends. This is the earliest use form of the stretch film, and thus more packaging forms have been developed.
2. Full width packaging
This type of packaging requires a film width sufficient to cover the tray. The shape of the tray is regular, so it has its own shape and is suitable for a film thickness of 17 to 35 μm.
3. Hand packaging
This type of packaging is the simplest of the stretch film packages, which are mounted on a stand or held by a hand, rotated by a tray or film wound around a tray. It is mainly used for repackaging after the packaged tray is damaged, and for ordinary tray packaging. The packaging speed is slow, and the suitable film thickness is 15-20 μm;
4. Stretch film winding machine packaging
This is the most common and widespread form of mechanical packaging, with the tray rotating or the film rotating around the tray, and the film is attached to the holder for up and down movement. This packaging capacity is very large, about 15 to 18 plates per hour. Suitable film thickness is about 15 ~ 25μm;
5. Horizontal mechanical packaging
Different from other packaging, the film is rotated around the article, suitable for long cargo packaging, such as carpet, board, fiberboard, profiled materials, etc.;
6. Paper tube packaging
This is one of the newest uses of stretch film, which is better than the wrap film packaging for old-fashioned paper tube packaging. Suitable film thickness is 30-120 μm;
7. Packaging of small items
This is the latest packaging form of stretch film, which can reduce material consumption and reduce the storage space of the tray. In foreign countries, this package was originally introduced in 1984. Just one year later, many such packages appeared on the market. This form of packaging has great potential. Suitable for film thickness 15 ~ 30μm;
