Post-press processing of printed cartons has strict requirements on adhesive appearance and performance, and hot melt glue is widely used in carton folding and bonding processes. It is applicable for edge bonding, window patching and local fixing of color printed cartons, coated cartons and offset printing packaging boxes. The transparent and non-yellowing glue layer will not damage the printed pattern and surface coating, ensuring the aesthetic degree of printed packaging. With fast positioning speed, it solves the offset and dislocation problems of carton folding during post-press processing. It has good compatibility with printed paper surfaces, no corrosion or damage to printing ink, and maintains long-term stable bonding effect for finished printed carton products.
