DuPont Nucrel AE resin for extrusion coating and extrusion laminating is said to enhance adhesion to aluminum foil and metallized film when blended into LDPE. Benefits are said to include increased line speed without sacrificing adhesion to metal; improvement in heat seal and hot-tack performance compared to LDPE alone; and decreased process temperatures for improved taste and odor. Resins can be used in snack and dry food structures and in other foil-containing pouches and sachets for non-aggressive products. Also can be used in non-packaging applications such as industrial coatings.
