Description
Features:
(1) Narrow width and light weight, suitable for the packaging of small goods
(2) For the packaging of cables, pipe fittings, hardware and other products, materials can be saved
(3) Not only for manual packaging, but also for mechanical packaging
(4) It can not only replace the packing tape to bind the material, but also can play the role of dustproof and protection

The stretching forms of pallet mechanical packaging include direct stretching and pre-stretching. There are two kinds of pre-stretching, one is roll-type pre-stretching, and the other is electro-stretching. Complete direct drawing between tray and drawing film. This method has a low extraction rate (about 15% to 20%). If the stretch ratio is greater than 55%~60% and higher than the initial yield point of the stretched film, the width of the stretched film will decrease, the perforation performance will also be lost, and the stretched film will be easily broken. 60% tension is still great. For light weight items, it may deform the item.
Stretching the machine wrap film before packaging can not only improve the stretch performance, but also change its puncture resistance and viscosity. If its tensile properties remain unchanged, it is easy to cause insufficient tension when packaging certain products. Some users will think that the purchased stretch film products are inappropriate and of poor quality, which indirectly affects the economic benefits of stretch film manufacturers. Therefore, according to relevant regulations, it should be stretched before packaging.
Storage conditions:
Stretch wrapping film is a kind of plastic, and plastic is a kind of raw material that is very easy to be embrittled. The quality and service life of plastic products are closely related to the embrittlement of plastic. Choosing the appropriate method can reasonably improve the quality of all products. and its quality
1. The local temperature should not be too high or too low, it should be between -15℃~40℃.
2. If the stretch film has not been used for a long time, it should be rolled frequently.
3. When storing the stretch wrapping film, it should be placed in a tray, not stretched; avoid wind, sun, rain,
4. Dissuade the stretched film from contacting with strong acids, alkalis and solvents, and persevere in cleaning the film, which is boring;
