A Stretch Wrapping Machine with a Pre-Stretch Unit is a highly efficient system used for wrapping Carton boxes or any load you want to wrap. The pre-stretch unit plays a crucial role in stretching the film before it is applied to the cartons, offering significant benefits in terms of film usage, load stability, and overall wrapping quality. The pre-stretch process can elongate the film by 200-300% or more, depending on the machine settings and the film properties.
