Aug 15, 2019

Shrink packaging machine is heating through heat pipe, using high power fan through a specially designed knife to blow out the hot air evenly from the heating cavity;Shrinkage principle is the use of thermal shrinkage film in the constant temperature and heat state, the original molecules between the irregular arrangement of the change, in the hot wind radiation, plastic molecules rearrangement, so that the original area greatly reduced, tightly attached to the product surface to achieve packaging purposes.
