Heat shrink packaging machine is widely used in food, beverage, cosmetics, medicine, electrical appliances, toys and other industries. They can package products of various sizes and shapes, giving them better protective performance and visibility.
Heat shrink packaging machine is a device for packaging products, its working principle is through heating and shrinking, the product packaging in heat shrink film, to achieve the purpose of protection and beauty.
Step 1 Heat up
Heat shrink packaging machines use electronic or gas heaters to provide constant heating. They transfer heat to the heat shrink film by way of conduction, allowing the film to soften and encapsulate the product.
Step 2 Shrink
Once the heat shrink film is heated to a certain temperature, it begins to shrink. The shrinkage process is mainly determined by two factors, the first is the internal structure of the heat shrink film, and the second is the temperature of the external environment.
3. Mechanical structure
The heat shrink packaging machine usually consists of a conveyor belt, a heating chamber and a shrinking area. The conveyor belt is used to carry the product to be packaged to the heating chamber. The heating chamber contains one or more heaters that provide the required heat. The heat shrink film is pulled from the roller, sent over the product by conveyor belt, and then lowered to enclose the product. When the packaging is complete, it enters the shrink zone, where the film is heated to shrink to the desired size.
