Introduction:
PE ultra-thin winding protective film is mainly divided into two types: stretch film for machine and hand stretch film. Machine stretch film has the characteristics of high tensile strength and good puncture performance. The stretching ratio is 2.5-4 times, and the product is stable, especially the film thickness is uniform, so the use of stretch film can ensure low unit consumption and reduce overall costs. At the same time, MLLDPEE needs to be added in the production of machine stretch film, so the general price is higher than that of hand stretch film.
The machine-use stretch film needs to be used by the winding machine, which can complete the packaging automation. It is suitable for the units with large dosage, frequent use or high degree of automation.
