DuPont Nucrel® 30707SR Ethylene-Acrylic Acid Copolymer Resin for Film and Extrusion Coating (discontinued **)
Categories:	Polymer; Film; Thermoplastic; Ethylene Acrylic Acid
Material Notes:	7 wt% Acrylic Acid. Nucrel® 30707SR 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 vs. Nucrel® 30707: Slip additives are added to reduce the coefficient of friction of the film surface to increase operating speeds on packaging machinery. Chill roll release agents are added to enhance extrusion coating speeds by reducing tendency of the hot melt to adhere to the chill roll surface. 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.
