Dow DOWLEX™ IP-2580 Linear Low Density Polyethylene
Categories:	Polymer; Thermoplastic; Polyethylene (PE); Linear Low Density (LLDPE); Linear Low Density Polyethylene (LLDPE), Injection Molded
Material Notes:	Next Generation DOWLEX® IP-2580 resin is an improved processing linear low density polyethylene resin designed for excellent flow and stiffness with freezer grade impact properties. DOWLEX IP-2580 resin balances peak molecular weight with patented molecular weight distribution and a slightly higher density for better lid stiffness and handling. Produced under U.S. patent number 5,015,511 this resin provides the processability, stress crack resistance, and rigidity needed for down gauging a variety of lids. This material complies with FDA regulation 21 CFR 177.1520 c 3.1(a) for food packaging applications. The regulation should be consulted for complete details. Data provided by Dow Chemical.
