Hot melt adhesive is non-toxic and tasteless, and can ensure food safety. Hot melt adhesive is solid at room temperature, only melts at high temperature, and is solid after cooling, so hot melt glue machine is needed for food packaging. The hot melt glue machine can automatically apply glue and accurately control the amount of glue, which is economical and beautiful.

The food industry is an important industry, directly related to the lives and health of consumers. With the development of technology and economy, people's living standards are improving, the demand for food is increasing, and the quality of packaging also affects the safety of food. As the saying goes, diseases are imported from the mouth, and consumers not only have higher requirements for food, but also have high requirements for food packaging. Therefore, the technology of hot melt glue applicator is continuously improved. The automatic spray nozzles system can continuously select the appropriate spraying method according to the needs of customers. For small carton packaging, the hot glue gun combined hose and machine can generally be matched with a cartoning machine, which automatically sprays glue at the two ends of the carton to realize the automation of food packaging.

Hot melt glue spraying machine has various methods such as automatic, semi-automatic and manual. Now most food manufacturers use semi-automatic packaging machines, which are more beautiful, safe, simple and material-saving, and meet the basic requirements of manufacturers for packaging.
