A heat shrink machine is usually used in conjunction with a beverage film packaging machine. By installing a shrink film on the outside of the product through a film sealing and cutting machine and sealing it, it enters the heat shrink machine for heating, causing the packaging material to shrink and tightly wrap around the product. The packaged items have a certain degree of anti fouling and impact resistance. Different beverage companies on the market have different requirements for beverage packaging bottles (cans), including 6 bottles, 12 bottles, 24 bottles, etc. Therefore, beverage film packaging machines and heat shrink machines are required to adapt to market requirements.
