Good packing quality transport carton must withstand temperature changes and rough treatment, but due to poor bonding strength, it is difficult to meet this requirement, tensile strength is small, coating or oily cardboard is not sticky.
Hot melt adhesives and wet materials have a good adhesive force, and has a strong penetration, at the same time between corrugated and lining paper play physical and chemical bonding.
The whole strength of bonded carton is strengthened, carton is not easy to deform and crack.In addition, a hot-melt adhesive coating system can apply adhesives to key components of various shapes, such as the folding lid of a carton.
Second, dry tape resistance to low temperature, in the cold climate in the north easy to open, hot melt adhesive has a good low temperature resistance, can withstand 40 degrees below zero.
In addition, hot melt adhesive storage life up to 2 years, small storage area, no special storage requirements.Dry tape will last only half a year.
Nowadays, businesses require packaging to convey product and corporate image through packaging design.Therefore, the fewer barriers to appearance the better.
