Adhesive For Book Binding

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. Second, the low temperature resistance of the self-adhesive tape is poor
