| LD02520 is designed for heavy duty film applications. Superior puncture resistance combined with excellent impact properties make this resin an ideal choice for bags used to package fertilizer, peat moss, decorative stone and agricultural and construction materials. LD02520 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 (165°-221°C) and blow-up ratios between 1.8:1 and 2.5:1. Drawdown to 1.5 mil (38.1 microns) is possible at commercial rates when proper extrusion techniques are used. Specific recommendations can be made only when the end use applications, required properties and processing equipment are known. For exact recommendations, contact your Osterman Sales Representative. ? Osterlene LD02520 meets the requirements of the Food and Drug Administration, 21 CFR Section 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 may apply.
