Material Notes:
PETROTHENE NA426 is a series of LDPE/EVA copolymer resins for high impact and clarity packaging film. These resins exhibit excellent a broad range of extrusion conditions. Well-balanced films with excellent optics, good stiffness and strong heat sealing characters can be produced from these resins.Regulatory Status: The NA426 resins meet 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 further information. NA426 resins have 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 NA426 can be made only when the end use application, required properties and the processing equipment are known. For exact recommendations, please contact your Equistar representative.This product is from the former Equistar product line.
