Polyurethane Adhesive for Dry Lamination

KAISHIMEI polyurethane adhesive for dry lamination is a high performance bi-component solvent based PU adhesive. It complies with the food hygienic standard and is widely used for dry bond lamination of all kinds of flexible packaging materials and other films such as PET, NY, OPP, PE, CPP, NY, VMPET, aluminum foil, etc.

Due to moderate viscosity, great leveling property, high transparency, strong adhesive power, perfect film-forming property, great heat, freezing and media corrosion resistance as well as stable quality and good adaptability, the dry lamination adhesive is an ideal choice for bonding the flexible packaging materials of food, medicine and other objects.

Product Features
1. Our polyurethane adhesive for dry lamination comes with outstanding bonding effect to a variety of film substrates, especially to those that are hard to bond such as complex PVC and thick PE.
2. With excellent temperciance and fast curing characteristic, this flexible packaging adhesive is suitable for the lamination of rigid materials like aluminum foils as well as the lamination of the flexible packaging materials which requires fast curing.
3. The laminating adhesive has terrific resistance to hydrolysis, high and low temperature, corrosion by sour and hot media, boiling and steaming, acid and alkali, etc.
4. Prominent wetting ability and leveling property make the polyurethane adhesive for dry lamination perfect for coating cloth at high or middle speed and laminating highly transparent flexible materials.
