Dry laminating is a widely used process in the packaging industry for bonding different layers of materials. However, several common problems may occur during this process, including poor adhesion, bubbles, wrinkling, and color change.

The market status of solvent-based polyurethane laminating adhesives in the food flexible packaging industry

YH-928 has good weather resistance, resistance to yellowing. Good resistance tomoisture and heat aging, good adhesion on the PVC substrate, activation temperature110~ 130 degrees, and good interlayer adhesion to the printing ink after activation.

YH-9172 is designed for the high efficiency and economy of composite films in packaging industry, and is suitable for general composite packaging products. It is excellent with character of good fluidity, infiltration, transferability and adapts to the high-speed production process.

EVA hot melt adhesive, whose main component is ethylene-vinyl acetate copolymer, is a polymer formed by the high-pressure copolymerization reaction of ethylene and vinyl acetate. At room temperature, it appears in a solid state, quiet and calm; once heated, it will quickly melt into liquid.

YH-9870A/B is a universal two-component polyurethane adhesive with a wider range of applicability and higher performance, with high initial tack and high peel strength for composite products.

Solvent-based adhesives have some advantages in the food packaging industry. Good Bonding Strength and Versatility - They can form a strong bond between different packaging materials, such as paper, cardboard, plastic films, and aluminum foil. This is crucial for ensuring the integrity of food packa

Hot melt adhesives are thermoplastic adhesives. They are solid at room temperature but turn into a liquid when heated. This allows them to be easily applied to surfaces. For example, you can use a hot glue gun to heat the hot melt adhesive sticks. As the glue is heated, it becomes a viscous liquid.

Water-based adhesives have become increasingly popular across various industries, including packaging, woodworking, and construction. Their widespread use raises an important safety question: are they flammable? Understanding whether water-based adhesives pose a fire hazard is crucial for industries

Water-based adhesives are becoming a popular choice across industries due to their environmentally friendly properties, cost-effectiveness, and versatility. As companies move towards more sustainable solutions, the advantages of water-based adhesives, such as their non-toxic nature and ease of use,
