Material Notes:
18 wt% Vinyl Acetate.Elvax® 3173SHB is an extrudable ethylene-vinyl acetate copolymer resin available in pellet form for use in conventional extrusion equipment designed to process polyethylene resins.Additives: Slip, Antiblock, Non-BHT antioxidant.Applications: Elvax® 3173SHB 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® 3173SHB is typically used as a low-temperature seal layer in coextruded films. Information provided by DuPont Packaging Polymers.
