According to the different packaging and wrapping methods of the pallet stretch wrapping machine, it can be divided into the following type:
1. Pallet stretch wrapping machine:It adopts a resistive stretching mechanism to cause the stretched film to be stretched at a slower speed than the tray rotating speed, and then wraps around the package at the time when the stretched film is stretched.
2. Pre stretch wrapping machine:It is stretched according to a pre-set "stretch ratio" and wrapped around the packaged goods by a pre-stretched mold frame structure.
3. Tapedwrapping machine: it is using programmable variable frequency controller, plus photoelectric detection system, automatically determine the height of the packaged object, through the program control of the pressing device automatically pressurize the goods to prevent the packaged objects from scattering.
