AB - Currently in industries, different types of adhesive products are being used in packaging industries. On the basis of chemistries, lamination adhesives are classified as water-based adhesive, solvent-based adhesive, solvent less adhesive, 100% solid based adhesive. The thin, two-dimensional substrates like plastic films, metal foils, paper, and cardboard are joined with these crosslinking or physically setting adhesives, which may be solvent-containing or solvent-free. Water-based adhesive based on acrylic emulsion, vinyl acetate-acrylic, ethylene vinyl acetate copolymer, acrylic dispersion, and polyurethane dispersion are utilised in the lamination industries, however polyurethanes are the most widely used laminating adhesive resins in the market. They have a long history of use, excellent all-purpose adhesion, and a wide range of performance abilities. The basic elements of polyurethanes are isocyanates and polyols. Adhesives suitable for the packaging sector include polyurethane hot-melt adhesives and one- or two-component polyurethane adhesives. The adhesives may contain solvent, though they are preferred solvent-free. Aromatic polyester, polyether polyols, and aromatic isocyanates comprise the majority of the domestic raw ingredients used to synthesize polyurethanes. The (- C - O - C -) linkage enables to generalize the polyether backbone. The adhesive that results from a reaction or extension with isocyanate could be referred to as a polyether or polyester urethane. Catalyst, polymerization control agents, inhibitors, antioxidants, wetting agents, adhesion promoters, fillers, and similar substances are examples of these materials. This paper has covered polyurethane lamination adhesives, their benefits and drawbacks, the raw materials utilised in their synthesis, potential applications, and testing procedures.
