Highly functional ethylene-acrylic acid (EAA) copolymer with controlled sodium ion neutralization for enhanced polarity and adhesion.
Excellent hot-melt processability and low melt viscosity, enabling smooth extrusion and coating at moderate temperatures.
Superior bond strength to polar substrates including aluminum foil, PET, paperboard, and metallized films.
Improved moisture and chemical resistance compared to non-ionomer EAA grades, supporting demanding packaging environments.
Clean melting behavior with minimal volatiles and low odor—ideal for food-contact compliant laminations.
Flexible packaging laminating adhesive for retortable pouches and stand-up pouches.
Heat-seal layer in multilayer coextruded structures for medical device packaging.
Adhesive tie-layer in foil–polymer or film–paper laminates for pharmaceutical blister lidding.
Functional additive in hot-melt adhesives to boost substrate affinity and cohesive strength.
Coating binder for high-barrier metallized PET and aluminum foil applications.
