Direct answer: For paper bag rope adhesion, hot melt adhesive particles with high initial adhesion, good flexibility, and a softening point of 75-85 ℃ should be used. The diameter of the adhesive point should be 8-12mm, with one point at each rope hole. Press and hold for 3-5 seconds.The key is not in the amount […]
Direct answer:Hot melt adhesive pelletsThe most direct consequence of high moisture content is the formation of bubbles, intermittent glue lines, and decreased bonding strength during the melting process. In severe cases, the glue layer may turn white and the spine may become hollow. EVA rubber particles themselves do not have strong moisture absorption, but after […]
Direct answer: For adhesive PP woven bags, APAO or POE based ones should be preferredHot melt adhesive pelletsDo not use regular EVA. The reason is that PP belongs to low surface energy materials (about 30 mN/m), and the EVA adhesive layer is almost unable to effectively wet it. When it sticks on, it does not […]
Photo books (album books) often use thick copperplate paper and pearlescent paper, which have high weight, smooth surface, and high requirements for initial adhesion and flexibility of the adhesive. Direct conclusion: Prioritize the transparent high initial adhesion EVA system and select the softening point according to the thickness of the book core. Selection List Procurement […]
