Material Notes:
12 wt% Vinyl Acetate.Elvax® 3135SB 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; Antioxidant.Applications: Elvax® 3135SB 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. Films from this resin exhibit excellent puncture resistance, good processibility, a high degree of stretch, and are typically used in poultry/meat and produce packaging applications.
