Applications
PETROTHENE NA 940 is a series of resins designed for heavy duty film applications. Superior puncture resistance combined with excellent impact properties make NA 940 an ideal choice for bags used to package fertilizer, peat moss, decorative stone and agricultural and construction materials.

Certification
NA 940 meets the requirements of the Food and Drug Administration regulation, 21 CFR 177.1520. This regulation allows the use of this olefin polymer 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 Techniques
NA 940 has been designed for excellent processability, bubble stability and good heat sealing over a wide range of extrusion conditions. Optimum properties are found at melt temperatures of 330°430°F and blow-up ratios between 1.8:1 and 2.5:1. Drawdown to 1.5 mil is possible at commercial rates when proper extrusion techniques are used. Specific recommendations for processing NA 940 can be made only when the end use applications, required properties and processing equipment are known. For exact recommendations, contact your Equistar sales representative.
