Food packaging requires strict safety standards for auxiliary materials, and food-grade hot melt glue has become a trusted bonding material for food packaging manufacturing. This type of hot melt glue adopts environmentally friendly raw materials, contains no volatile harmful substances, and complies with international food packaging safety regulations. It is widely used for bonding snack boxes, food cartons, takeaway packaging and bakery paper containers. The adhesive features pure physical melting and curing, no chemical reaction during application, and no odor residue on packaging surfaces. It maintains stable bonding performance in low and room temperature environments, avoiding degumming caused by temperature changes during food storage and transportation. With non-toxic and tasteless characteristics, it ensures food packaging hygiene while realizing efficient and firm packaging sealing.
