Applications
The PETROTHENE GA 502 series of resins are pelletized linear low density polyethylene for film extrusion applications requiring excellent drawdown and toughness. These pelletized products offer excellent additive homogeneity, require no transfer equipment modifications and facilitate clean and safe storage and handling. They can be used in either blown or cast film extrusion. GA 502-024 is specifically formulated with extra antioxidant for use in cast film. It contains no other additives.
Processing Techniques
GA 502 series resins exhibit excellent drawdown characteristics. Recommended conditions are 375-425°F melt temperature and a 1.5-3.0:1 blow-up ratio. Using proper techniques, these products can readily be drawn below .5 mil at optimum production rates. Specific recommendations for type of resin and extrusion conditions can be made only when the end use, required properties and processing equipment are known.
Regulatory Status
GA 502 meets the requirements of the Food and Drug Administration regulation, 21 CFR 177.1520, Subpart C, Item 3.1. 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.
