Quick Sealing Box Packing Hot Melt Adhesive

The hot melt adhesive sealing box is the use of Hot Melt Machine to melt the hot melt adhesive into a liquid, through the throat and spray gun, coated on the surface of the carton, and the hot melt adhesive is completed after cooling.

The use of hot melt adhesive for packaging and sealing can not only meet the requirements of sealing boxes, but also overcome the defects of traditional sealing forms. The main advantages of hot melt sealing are listed below.

1. Strong ability to cope with environmental changes

The storage and transportation of the carton must be subjected to temperature, humidity changes and possible brutal loading and unloading, the use of traditional tape sealing box, because of its poor bonding strength, small tensile strength, and for coated or oily cardboard is not strong, so it is possible to change in the environment and loading and unloading vibration, extrusion, deformation process caused by the seal off, so sometimes can not fully meet the requirements.

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 key stress parts, such as: carton folding cover, play a supporting role.

Secondly, the traditional tape has poor low temperature resistance, and it is easy to open in the cold climate in the north; Hot melt adhesive has good low temperature resistance and can withstand -40℃ low temperature.

In addition, the storage period of hot melt adhesive is up to 2 years, the storage area is small, and there is no special requirement for the storage environment; The validity period of tape storage is only half a year, and the storage conditions are harsh, otherwise it is easy to deteriorate.

2. Strong anti-theft function

Hot melt adhesive provides a good anti-theft function, because the adhesive penetrates into the corrugated, any attempt to open the carton will tear the fiber, so it is difficult to tear, but it is easy to find after tearing. And if the use of traditional tape, it is easy to cut with a knife, unknowingly take the items in the box, sealed again, undetected, not easy to be found.

3. Low 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. Using hot melt adhesive, no need to stop during the gluing process; If the traditional tape is used to seal the box, the replacement tape needs to be stopped.

In addition, due to the high sealing strength of the hot melt adhesive box, the box can not be installed with a partition, and the tape is used to seal the box, because the adhesive strength is low, often need to use a partition to increase the sealing strength. It can be seen that the use of hot melt adhesive sealing box can save materials and reduce costs.

4. Look good

Nowadays, businesses require packaging to transmit goods at the same time, but also through packaging patterns, design, etc., to reflect the image of products and companies, play the role of advertising and marketing. As a result, the fewer obstacles to appearance, the better. The use of traditional bundling or tape often blocks the pattern and interferes with the transmission of packaging information; The hot melt adhesive is glued between the folded wings, which can provide a larger and more complete display space.
