Applications
PETROTHENE NA 942 is a series of resins designed especially for heavy duty film applications, such as bags used to package fertilizer, peat moss, decorative stone, and agricultural and construction materials. NA 942 exhibits excellent impact properties and puncture resistance.
Regulatory Status
NA 942 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.
Processing Techniques
Generally recommended extrusion conditions include a melt temperature range of 330°430°F; a blow-up ratio range of 1.8-2.5:1. Drawdown to 2.0 mils is possible at commercial rates when proper extrusion techniques are used. Specific recommendations for processing NA 942 can be made only when the end use applications, required properties and processing equipment are known.
