| 7 wt% Acrylic Acid. Nucrel® 30707HS 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 foil and low-density polyethylene (LDPE). In extrusion coating applications, 7 MFI provides better performance in internally deckled dies compared to higher MFI extrusion coating resins. Higher drawability for thinner coatings and/or higher extrusion speeds. 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. This product line/trade name was acquired by Dow, but this specific grade was discontinued prior to the acquisition. |
