Dow Nucrel® 31001 Ethylene-Acrylic Acid Copolymer Resin for Blown and Cast Film
Categories: Polymer; Film; Thermoplastic; Ethylene Acrylic Acid
Material Notes: 9.5 wt% Acrylic Acid.

Nucrel® 31001 is an ethylene-acrylic acid copolymer resin available for use in blown and cast film extrusion and coextrusion equipment designed to process polyethylene resins.

Features/Benefits: Excellent adhesion to coextruded nylon for superior structure reliability and barrier integrity. High film strength for excellent structure reliability and product protection. Very good hot tack, sealability through contamination, and heat seal strength for strong, reliable heat seals.

Typical Applications: Meat, poultry, seafood, and cheese packaging. Medical/pharmaceutical packaging. Edible oil, motor oil, and other liquid product pouches. Coextrusions with nylon or in other film structures as a heat seal or tie layer.

Information provided by DuPont Packaging Polymers.

This former DuPont product line is now a Dow product line.
