Highly functional ethylene-acrylic acid (EAA) copolymer with controlled sodium ion neutralization for enhanced polarity and adhesion.
Excellent hot-melt processability—melts cleanly at low temperatures with low melt viscosity for efficient extrusion and coating.
Superior bond strength to polar substrates including metals, glass, PET, and treated polyolefins without primers.
Outstanding moisture and chemical resistance due to ionic crosslinking network formed by carboxylate salt clusters.
Good thermal stability and low extractables—suitable for food-contact-compliant packaging applications when processed per regulatory guidelines.
Heat-seal layers in flexible food packaging laminates (e.g., pouches, stand-up bags).
Adhesive tie-layer in multilayer coextruded films for barrier packaging.
Coating formulation component for metallized film surface treatment and print primer systems.
Functional additive in hot-melt adhesives requiring improved substrate wetting and cohesive strength.
Encapsulation binder for controlled-release agricultural granules and pharmaceutical tablet coatings.
