Performance Characteristics of Sealing Hot Melt Adhesive
1. The folding package is of good quality
Shipping cartons must be able to withstand temperature, humidity changes and rough handling, but the use of tape is more difficult to meet this requirement, because of its poor bonding strength, low tensile strength, and for coated or oily cardboard is not strong.
The hot melt adhesive has a good bonding force with the wet material, strong penetration, and plays a physical and chemical bonding role between the corrugated paper and the lined paper board. The overall strength of the carton after bonding is enhanced, and the carton is not easy to deform and crack. In addition, the hot melt adhesive coating system can be applied to a variety of different shapes of the key parts, such as: carton folding lid.
2. Good performance on anti low temperature
Second, the low temperature resistance of the self-adhesive tape is poor, in the cold climate in the north, easy to open the glue; Hot melt adhesive has good low temperature resistance, can withstand -40℃ low temperature. Moreover, the storage period of hot melt adhesive is up to 2 years, the storage area is small, and there is no special storage requirements; The validity period of tape storage is only half a year, and certain storage conditions are also required, otherwise it is easy to deteriorate.
3. Anti-theft performance is strong
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 fibers. The tape can be cut with a knife, unknowingly removing the contents and sealing them again.
4. Good appearance
Nowadays, businesses require packaging to transmit goods at the same time, but also through the packaging pattern design to convey the product and company image. As a result, the fewer obstacles to appearance, the better. Tape often blocks the image and interferes with the transmission of packaging information; The hot melt adhesive is glued between the folded wings, which can provide more display space.
5. Reduce folding cost
The use of hot melt adhesive sealing speed, the entire bonding process only takes 1 to 3 seconds to complete, suitable for mass production, less energy consumption, low cost. The sealing cost of standard corrugated box hot melt adhesive is about 32 yuan /1000 cases, which is the middle price of hot melt adhesive, and the middle price of tape sealing is about 120 yuan /1000 cases.
If hot melt glue is used, adding glue during processing will not cause downtime; Replacing the tape requires stopping the machine. Moreover, the box is not equipped with a partition, and the sealing strength is greater than the sealing strength of the partition when the tape is used to seal the box, which can reduce the cost of the partition.
