Dow DOWLEX™ NG 3347A Linear Low Density Polyethylene, Ethylene-Octene Copolymer
Categories:	Polymer; Film; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE); Linear Low Density Polyethylene (LLDPE), Film Grade; LLDPE/Octene, Film
Material Notes:	Next Generation DOWLEX® NG 3347A resin with extra stretch performance (ESP)is an ethylene-octene-1 copolymer designed for cast stretch film applications such as industrial pallet wrap. DOWLEX NG 3347A with ESP provides stretch films with superior extensibility and increased resistance to failure around film flaws while maintaining exceptional puncture resistance and load retention. This material complies with U.S. FDA regulation 21 CFR 177.1520 c 3.1(a) for food contact applications. The regulation should be consulted for complete details. Film properties below based on a film thickness of 25 µm. Data provided by Dow Chemical.
