An automatic side sealing and shrinking machine is a type of packaging machinery that is used to package a variety of products. It is called a side sealing machine because it seals the sides of the product packaging rather than the top or bottom.

The machine works by first forming a tube of packaging material around the product. The tube is then sealed along the sides using heat, depending on the type of machine. The excess material is then trimmed off to create a neat, finished package. Then the covered products will be sent to a heating room and shrinked.

Automatic side sealing and shrinking machines are often used in the food, beverage, and pharmaceutical industries, as well as in other industries that require high-speed and efficient packaging. They can be used to package a wide range of products, from small items like candy and snacks to larger items like electronic components and automotive parts.
