Hot-melt adhesive sealing is the use of a hot melt machine to melt the hot melt into a liquid, which is then sent to the surface of the carton through the throat of the hot melt machine and the spray gun.

Transport cartons must be able to withstand temperature and humidity changes and rough handling, but it is difficult to meet this requirement with adhesive tape because of poor adhesive strength, low tensile strength, and poor adhesion to coated or oily paperboard.
The hot melt adhesive has good binding force with the wet product, strong penetration force, physical and chemical bonding effect between the corrugated paper and the linerboard, and the integrated strength of the bonded carton is enhanced, and the carton is not easy to be deformed and cracked. In addition, the hot melt adhesive coating system can apply pressure on key parts of various shapes, such as folding lids in cartons.
Hot melt adhesive sealing advantages
Hot-melt adhesives also provide good anti-theft protection. As the adhesive penetrates into the corrugated medium, any attempt to open the carton tears the fibers. The tape can be cut with a knife, and the contents are removed and sealed again unconsciously.
