Material Notes:
ApplicationsPETROTHENE NA 420 is a LDPE/EVA copolymer resin for high impact and clarity packaging film. This resin exhibits excellent processability over a broad range of extrusion conditions. Well-balance films with excellent optics, good stiffness and strong heat sealing characters can be produced from this resin. Regulatory StatusNA 420 meets the requirements of the Food and Drug Administration regulation 21 CFR 177.1350. This regulation allows the use of this ethylene vinyl acetate copolymer "…in articles or components of articles intended for use in contact with food." Specific limitations or conditions of use may apply. Contact your Equistar sales representative for more information. Processing TechniquesNA 420 has excellent drawdown characteristics that yield outstanding output rates. Recommended extrusion conditions are 330°-380°F (166°-194°C) melt temperatures and a blow-up ratio between 1.7-3.0:1. Specific recommendations for the processing of NA 420 can be made only wThis product is from the former Equistar product line.
