Description

Technical Field

[0001] The utility model relates to the technical field of heat sealing of plastic bags, in particular to a heat sealing device based on plastic bags. Background Art

[0002] Plastic bags are bags made of plastic (commonly used plastics include polypropylene, polyester, nylon, etc.) as the main raw material. They are indispensable items in people's daily lives and are often used to hold other items. They are widely used because of their low price, extremely light weight, large capacity, and easy storage. Hot press sealing is to heat the sealing material in a certain way to make it reach a viscous flow state and then pressurize it to make it sticky. It is generally completed with a hot press sealing device or a hot press sealing machine. The heat sealing head is the actuator of the hot press sealing. According to the different structural forms of the heat sealing head and the heating method, the hot press sealing methods can be divided into: ordinary hot press sealing, fuse sealing, pulse sealing, ultrasonic sealing, high-frequency heat sealing, and induction heat sealing.

It also has a good effect of air purification and adsorption, and reduces pollution to the inside of the plastic bag.
