Highly functional ethylene-acrylic acid (EAA) copolymer with controlled sodium ionomer crosslinking for enhanced melt strength and toughness.
Excellent adhesion to polar substrates including aluminum foil, PET, nylon, and paper without primers or corona treatment.
Superior hot-tack performance and rapid set time ideal for high-speed packaging lamination and coating processes.
Good thermal stability and consistent rheology across processing temperatures (140–180 °C).
Low extractables and compliant with FDA 21 CFR §177.1350 for repeated-use food-contact applications.
Heat-sealable coatings for flexible food packaging laminates (e.g., snack pouches, coffee bags).
Adhesive tie-layer in multilayer extrusion structures combining polyolefins with barrier films.
Functional additive in hot-melt adhesives requiring improved cohesion and substrate bonding.
Coating binder for metallized paper and foil-based pharmaceutical blister packaging.
