EVA 3176 低温热封或其他材料常用于软包装应用
DuPont™ Elvax® 3176 is an extrudable ethylene-vinyl acetate copolymer resin available in pellet form for use in conventional extrusion equipment designed to process polyethylene resins.
Composition
18 % By Weight Vinyl Acetate comonomer content
Chill Roll Release additive, Slip additive
Thermal Stabilizer: BHT antioxidant,
Applications
This resin 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 extrusion coating and cast film equipment over a wide range of line speeds and film thicknesses. Typically, cast film of this grade is adhesive laminated to polyester or other substrates as required by the application.
