When using a heat shrink packaging machine, the products to be shrunk are first placed together. During the first stage, film will fall onto the items to be packaged, but the packaging effect is not very good at this point. After passing the second stage, the effect is much better. For example, it's used for plastic film packaging of food and beer, resulting in a very attractive appearance. Heat shrink machines can also be combined with sterilization and drying machines to form a complete set of equipment for wrapping bowls and chopsticks.
