Applications
PETROTHENE NA 336 is a homopolymer resin specifically engineered for garment film and dry cleaning bag applications. This resin is also suitable for any application requiring thin gauge film constructions. NA 336 is know for its consistency, exceptional drawdown and processability.
Regulatory Status
NA 336 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
NA 336 is specifically designed to provide outstanding drawdown at maximum outputs. The melt strength properties of this resin result in excellent bubble stability. This resin can be processes over a wide range of temperatures; however, recommended conditions are melt temperatures between 300°-330°F and a blow-up ratio between 2.0-2.5:1. Using proper techniques and equipment, drawdown to 0.25 mil is feasible at commercial production rates. Specific recommendations for processing NA 336 can only be made when the processing conditions, equipment and end use are known.
