Powder Coating Grade Copolyester Hot Melt Adhesive For Can Manufacturing
Powder Coating Grade Copolyester Hot Melt Adhesive for Can Manufacturing are high-performance thermoplastic adhesive materials specially developed for metal packaging applications. Supplied in pellet (granule) form, the product can be ground into powder and applied through electrostatic or fluidized-bed powder coating processes.
After melting and curing, the adhesive forms a smooth, uniform, and durable coating on tinplate surfaces, providing excellent adhesion, flexibility, and corrosion protection. It is widely used in the coating of food cans, beverage cans, chemical containers, and other metal packaging products.
This copolyester hot melt adhesive is solvent-free, environmentally friendly, and suitable for modern, sustainable manufacturing systems.
