DOW™ LDPE 320E Low Density Polyethylene Resin

DOW LDPE 320E is a fractional melt index low density polyethylene resin. DOW LDPE 320E has been specially designed for the use in applications were high clarity and gloss are required. The improved optical performance can also be observed in LLDPE blends, more pronounced in LDPE rich structures. This resin due to its excellent draw down, allows for thin structures as required in some applications. Applications: Food packaging, Display packaging, Lamination films for consumer packaging, Main Characteristics: - Excellent processability and draw down - Designed for applications requiring exceptional optical performance, pure as well as in blends with LLDPE DOW LDPE 320E should comply with: - U.S. FDA 21 CFR 177.1520 ( c )2.2 - EU, No 10/2011 Consult the regulations for complete details. Slip Additive: 0 ppm Antiblock Additive: 0 ppm
