Hot-melt adhesive sealing uses a 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. After the hot-melt adhesive is cooled, the bonding is completed. It can meet various carton sealing requirements and overcome the defects existing in the traditional carton sealing form.


good quality packaging

Shipping cartons must withstand temperature, humidity changes, and rough handling. It is more challenging to meet with tape because of its poor bond strength, low tensile strength, and poor adhesion to coated or oil-based cardboard.


The hot melt adhesive has a reasonable bonding force with wet materials and has a strong penetration force. It plays a physical and chemical bonding effect between the corrugated paper and the lining board simultaneously. The overall strength of the bonded carton is enhanced, and the carton is not easy to deform and crack. In addition, the hot melt adhesive application system can apply glue to crucial parts of various shapes, such as carton inner flaps.


Secondly, the self-adhesive tape has poor low-temperature resistance. In the cold climate of the north, it is easy to open the glue; the hot melt adhesive has good low-temperature resistance and can withstand low temperatures of -40 °C. In addition, the storage period of hot melt adhesive is as long as 2 years, the storage area is small, and there are no special storage requirements; while the storage period of the tape is only half a year, and specific storage conditions are also required, otherwise it is easy to deteriorate.


Hot melt adhesive also provides an outstanding anti-theft feature. Any attempt to open the carton will tear the fibers as the adhesive penetrates the corrugation. The tape can be cut with a knife, unknowingly taking the contents and resealing it again.


beautiful appearance

Today, merchants require packaging to convey product and company image through packaging pattern design while delivering goods. Therefore, the fewer factors that hinder the appearance, the better. Tape often obstructs the image and interferes with the transmission of packaging information, while hot-melt glue is used to the bond between the flaps, which can provide larger display space.


low cost

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


If hot melt adhesive is used, adding glue during processing will not cause downtime, while replacing the tape requires downtime. In addition, the clapboard may not be installed in the box, and the sealing strength of the box is greater than that of the clapboard when the box is sealed with tape, which can reduce the cost of the clapboard.
