Pre stretch film or say pre-stretch film is a special type of stretch film. Pre stretching is completed by two rubber rollers, which are connected together by gear units. The pre stretch ratio is depending on the gear ratio.The tension is generated by the operation of the machine motor. As stretching occurs over a short distance, the friction between the rollers and the film is also high, resulting in the elongation of the stretch film and the preservation of the original winding protection of the film.
Pre stretch film is widely used in the combination (bundle) packaging of irregularly shaped items or commodities. It can not only meet the functions of moisture and dust prevention, anti touch theft, transparent display, etc. of commodities, but also increase the attractiveness of product appearance. It can also be used to replace various types of paper boxes, saving packaging costs
