Good quality of sealing hot melt adhesive packaging
Shipping cartons must be able to withstand temperature, humidity changes, and rough handling, which is more difficult 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 good 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 at the same time. 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 key parts of various shapes, such as: carton inner flaps.
High temperature resistance
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 temperature 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 certain storage conditions are also required, otherwise it is easy to deteriorate.
Strong anti-theft performance
Hot melt adhesive also provides a great anti-theft feature, as the adhesive penetrates into the corrugation any attempt to open the carton will tear the fibers. 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 bond between the flaps, which can provide a 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 middle price of hot melt adhesive, and the middle 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.
