Ethylene Copolymer

Copolymers of ethylene and acrylic acid (EAA) or methacrylic acid (EMAA) have ethylene segments that provide properties such as water resistance, flexibility, chemical resistance and flexibility. The presence of acrylic / methacrylic acid brings polarity, adhesion, toughness, hot tack strength and low temperature heat sealability. Increasing the acid content increases the adhesion to polar substrates, reduces the softening and melting temperatures, improves clarity and increases strength. These ethylene acrylic acid copolymers are heavily used in flexible packaging such as laminated tubes, condiment pouches and sachets, aseptic packaging, meat and cheese packaging, as well as protective metal coating, wire and cable and powder coating. Acrylic acid copolymer have also found use in aqueous dispersions, glass adhesives, and ink and paint formulations.
