Automatic bagging and sealing machine is a very popular packaging method today. Compared with cardboard packaging, heat shrink packaging can greatly reduce packaging costs, reduce the use of paper products, and is also a manifestation of energy conservation and environmental protection. There are many types of automatic bagging and sealing machines. The models and principles of heat shrink packaging are roughly the same. Manufacturers need to choose the appropriate shrinking machine model based on the customer's packaging requirements and the relevant characteristics of the product. Some products are suitable for different packaging methods, such as PE film with poor transparency, good toughness, and strong tensile strength, which is suitable for large shrink film packaging. Suitable for a large number of automatic shrink packaging projects such as canned goods, glass bottles, beer, mineral water, etc. Vigorously develop, produce and research equipment related to heat shrink packaging machines, and launch various series of heat shrink packaging machine products, such as high-speed heat shrink packaging machines, large-scale heat shrink packaging machine series, etc.
