Dow Elvax® 3170 Ethylene-Vinyl Acetate Copolymer Resin for Coextrusion, Blown Film
Categories:	Polymer; Film; Thermoplastic; Ethylene Vinyl Acetate; Ethylene Vinyl Acetate Copolymer (EVA), Extrusion/Coating Grade
Material Notes:	18 wt% Vinyl Acetate. Elvax® 3170 is an extrudable ethylene-vinyl acetate copolymer resin available in pellet form for use in conventional extrusion equipment designed to process polyethylene resins. Additives: Antioxidant.. Applications: Elvax® 3170 is designed to provide a low temperature heat seal to itself or many other materials commonly used in flexible packaging applications. The melt properties of this resin allow it to be processed on blown film equipment over a wide range of film thicknesses and blow-up ratios. It can also be coextruded with a variety of other polymers. Elvax® 3170 is typically used as a low temperature seal layer in coextruded films. Elvax® 3170S and 3170SHB are grades of Elvax® 3170 resin containing FDA approved additives and have been designed to provide films of improved slip and antiblock properties. Information provided by DuPont Packaging Polymers. This former DuPont product line is now a Dow product line.
