[China Packaging News] as a new sealing form of carton and carton packaging, hot melt adhesive sealing has partially replaced the traditional strapping packaging and tape packaging, and is applied to the carton outer packaging of various foods and the carton outer packaging of wine, dairy products and other products. Due to the advantages of good packaging quality, beautiful appearance and low cost, the application of hot melt adhesive sealing box will be more and more widely

advantages of hot melt adhesive box sealing

hot melt adhesive box sealing is to use the hot melt machine to melt the hot melt adhesive into a liquid, and then send it to the surface of the carton through the throat and spray gun of the hot melt machine. The hot melt adhesive is bonded after cooling. It can meet the requirements of carton sealing and overcome the defects of traditional carton sealing

good packaging quality

transport cartons must be able to withstand temperature, humidity changes and rough handling, but it is difficult to meet this requirement with adhesive tape because of its poor bonding strength, low tensile strength and poor adhesion to coated or oily cardboard

the hot melt adhesive has good adhesion with wet materials and strong penetration. It plays a physical and chemical bonding role between corrugated paper and liner board at the same time. The bonded cartons improve the safety and environmental protection performance of plastic packaging. The overall strength is enhanced, and the cartons are not easy to deform and crack. In addition, the hot melt adhesive coating system can apply the adhesive to the key parts of various shapes, such as the folding cover in the carton

secondly, the adhesive tape has poor low temperature resistance and is easy to open in the cold climate in the north; The hot melt adhesive has good low temperature resistance and can withstand -40 ℃. Moreover, the storage period of hot melt adhesive is up to 2 years, the storage area is small, and there are no special storage requirements; The storage period of adhesive tape is only half a year, and certain storage conditions are required, otherwise it is easy to deteriorate

hot melt adhesive also provides a good anti-theft function. As the adhesive penetrates into the corrugated, any attempt to open the carton will tear the fiber. The adhesive tape can be cut with a knife, and the contents can be removed and sealed again unconsciously for various reasons

If it is certain that the iron content in the lubricating oil is low

the cost is low

the speed of sealing the box with hot melt adhesive is fast, and the whole bonding process can be completed in only 1~3 seconds. It is suitable for mass production, with less energy consumption and low cost. The sealing cost of standard corrugated box hot melt adhesive is about 32 yuan/1000 boxes, which is the middle price of hot melt adhesive, while the middle price of tape sealing is about 120 yuan/1000 boxes

if hot melt adhesive is used, adding adhesive during processing will not cause shutdown; Replacing the tape requires shutdown. Moreover, the box may not be equipped with a partition board, and the sealing strength is greater than that of the case with a partition board inside when the box is sealed with adhesive tape, which can reduce the cost of the partition board

beautiful appearance

nowadays, businesses require that while packaging goods, they can also convey the product and company image through packaging pattern design. Therefore, the less factors that hinder the appearance, the better. The tape often blocks the image and interferes with the transmission of packaging information; The hot melt adhesive is bonded between the folding wings, which can provide a larger display space
