Copolyester hot melt adhesive are thermoplastic adhesive materials specially designed for metal packaging applications. The product is supplied in pellet (granule) form and can be processed into powder for electrostatic or fluidized-bed coating systems. After melting and curing, it forms a uniform, continuous, and durable adhesive coating on tinplate surfaces.
This copolyester hot melt adhesive exhibits excellent adhesion to tinned iron substrates, ensuring strong bonding performance and long-term coating stability. It provides good flexibility and toughness, preventing cracking or peeling during forming, seaming, or handling of cans. The coating also offers reliable resistance to moisture, chemicals, and corrosion, helping to protect metal surfaces and extend the service life of cans.
As a solvent-free and environmentally friendly material, the copolyester-based hot melt adhesive contains no volatile organic compounds (VOCs) and produces minimal emissions during processing. It is suitable for modern, sustainable manufacturing requirements in the metal packaging industry.
The pellets can be customized in terms of softening point, melt viscosity, hardness, and adhesion performance to meet different processing conditions and application needs. Typical processing involves grinding the pellets into fine powder, followed by powder coating and thermal curing at controlled temperatures to achieve optimal bonding and surface appearance.
This product is widely used in the coating of tinplate cans for food, beverage, chemical, and general industrial packaging, where reliable adhesion, coating integrity, and process stability are required.
