(Summary description)
New application
As a new type of carton and carton packaging sealing form, hot melt adhesive sealing has partially replaced traditional strapping packaging and tape sealing, and is used in various food carton outer packaging and wine and dairy products. The outer packaging of the product carton. Due to the advantages of good packaging quality, beautiful appearance and low cost, hot melt adhesive sealing applications will become more and more widespread.
2Packaging quality
　　The advantage of hot melt adhesive sealing is to use a hot melt machine to melt the hot melt into a liquid, and then send it to the surface of the carton through the hot melt machine throat and spray gun. After the hot melt adhesive cools, the bonding is completed. It can meet the requirements of carton sealing, and overcome the defects of traditional carton sealing form.
3 strong adhesion
　　 Transport cartons must be able to withstand temperature, humidity changes and rough handling, but it is difficult to meet this requirement with tape because of its poor bonding strength, low tensile strength, and it is not strong to coated or oily cardboard. The hot-melt adhesive has a good bonding force with wet objects and strong penetration. It simultaneously plays a physical and chemical bond between the corrugated paper and the liner board. After bonding, the overall strength of the carton is enhanced, and the carton is not easy to deform and crack. In addition, the hot-melt glue coating system can press glue on key parts of various shapes, such as the inner flap of a carton.
4 anti-theft function
　　 hot melt adhesive also provides a good anti-theft function. As the adhesive penetrates into the corrugation, any attempt to open the carton will tear the fiber. The tape can be cut with a knife, and the contents are removed unknowingly and sealed again.
5 beautiful appearance
　　 Nowadays, merchants require packaging to convey the product while also conveying the product and company image through the packaging pattern design. Therefore, the less obstructive factors in appearance, the better. Adhesive tape and strapping often obscure images and interfere with the transmission of packaging information; while hot melt adhesive is glued between the flaps to provide greater display space.
6 Widely used
　　 Hot melt for packaging and book binding At present, packaging and sealing of food, beverages, instant noodles, cigarettes, beer, medicine, etc. are mostly done by using hot melt through a box sealing machine. The book binding industry has now abolished the old thread and binding, and switched to hot-melt bonding technology, which not only improves the binding quality, but more importantly, greatly accelerates the binding speed.
