Comparison of the advantages of hot melt sealing glue and sealing glue.

Hot-melt sealing is different from general glue sealing. Hot-melt sealing solves the problem that general glue sealing cannot solve.

First of all, hot melt adhesive also provides a good anti-theft function, which solves the shortcomings of traditional glue sealing. Because the hot-melt adhesive penetrates into the paper, no matter how the carton is opened, the fibers will be torn, so that once the item is stolen, it is easy to find, and the sealing tape is used to seal the box and cut it with a knife. Take the items out of the carton and seal them with sealing tape. This is the advantage of hot-melt glue sealing over ordinary glue sealing.

 

Then, the hot-melt sealing adhesive is melted into a liquid by a hot-melt machine, and then adhered to the surface of the carton by the spray gun and the throat of the hot-melt machine. After the hot melt adhesive sealing tape is cold, the bonding process of the carton is completed. Hot-melt adhesive sealing can meet various requirements of carton sealing, and hot-melt sealing solves the shortcomings of traditional carton sealing.

 

In addition, hot melt adhesives are resistant to low temperatures and last longer than ordinary glues. Dry glue sealing tape has poor low temperature resistance and is easy to degumming at low temperature. The hot melt adhesive has good low temperature resistance and can withstand the low temperature of -40 ℃. Purking hot melt adhesive has been tested and can also play a good role in low temperature environment. The storage period of hot melt adhesive is as long as two years without special storage requirements; while the storage period of general tape is only half a year, which has high requirements on the storage environment, otherwise the stored glue will deteriorate quickly.

 

At the same time, hot melt adhesive has strong bonding strength and is suitable for the sealing of transport cartons. Because transport cartons require long-distance transportation, they have to withstand high temperature, humid weather and multiple loading and unloading during transportation. Generally, it is difficult for glue to solve this problem. , The characteristic of hot melt adhesive is to break through the shortage of general glue in transportation and sealing, so that the transportation carton is safe and not damaged during transportation.

 

Finally, the hot melt adhesive has a good bonding force with the wet material, and has a strong penetration force, which plays a physical and chemical bonding effect between the corrugated paper and the lining board at the same time. The carton bonded with hot melt glue is strong, the carton will not be deformed, and the carton will not crack. Hot melt adhesive has the functions of temperature resistance, water resistance and moisture resistance, and is the best choice for transporting cartons.
