SOLVENT-BASED polyurethane and polyester adhesives have been used in dried bond laminating adhesives for decades.

SOLVENT-BASED polyurethane and polyester adhesives have been used in dried bond laminating adhesives for decades, demonstrating pious adhesion on various substrates of that kind as aluminum foil, polypropylene (PP) polyethylene (PE) fondling and nylon. In the flexible forage packaging area, solvent-based urethane adhesives have always provided dutiful product resistance to moisture, fatty viandss and oil to meet the requirements for different viands packaging.

In response to industry directions and demands, extensive research has been focused forward developing water-based dry bond laminating adhesives that provide comparable performance to solvent-based adhesives. the couple acrylic latex and polyurethane dispersion (PUD) adhesives are publicly available. ...
