Resin offers up to 50% higher moisture barrier

Nova Chemicals (Pittsburgh, PA) has introduced a new ultrahigh-barrier high-density polyethylene resin for cast film and extrusion coating, promising up to 50% higher moisture-barrier improvement over conventional technology. Called SURPASS EX-HPs667-AB, the resin allows package redesign and improved sustainability for barrier packaging in markets such as snacks, beverages, dairy, pet foods, and lawn and garden applications.

Nova says processors can co-extrude the product and reduce film gauge to satisfy customers' performance and sustainability objectives. Alternatively, they can co-extrude or blend the product to enable lamination consolidation and performance enhancement.

SURPASS EX-HPs667-AB gives cast film and extrusion-coating processors the ability to custom-tailor solutions in-house to meet customer needs in a range of packaging formats, including stand-up pouches, lidstocks, release liners, and multilayer foil laminations, with the possibility of lamination step elimination for three-ply applications. Nova's ultrahigh-barrier resin portfolio for film applications also includes HPs167-AB resin for blown film.
