DuPont Nucrel® 30707 Ethylene-Acrylic Acid Copolymer Resin for Film and Extrusion Coating

7 wt% Acrylic Acid.Nucrel® 30707 is an ethylene-acrylic acid copolymer resin available for use in blown/cast film and extrusion coating operations. It can be used in both extrusion and coextrusion equipment designed to process polyethylene resins.Features/Benefits: Low seal initiation temperature allows high speed packaging. Very good hot tack, seal through contamination, and heat seal strength provides strong, reliable heat seals. Balanced acid content (7% AA) provides good adhesion to both aluminum and low-density polyethylene (LDPE). In film applications, 7 melt flow index (MFI) allows for very good wetting in thermal lamination processes. In extrusion coating applications, 7 MFI provides better performance in internally deckled dies compared to higher MFI extrusion coating resins.Typical Applications: Cable shield wrap. Sealants for sachets in both food and nonfood applications. Toothpaste tubes, as a foil/LDPE tie layer. Other foil-containing pouches and sachets. Medical/pharmaceutical packaging.Information provided by DuPont Packaging Polymers.
