LG Chemical SEETEC R3450 Polypropylene Random Copolymer
Categories:	Polymer; Thermoplastic; Polypropylene (PP); Polypropylene Copolymer
Material Notes:	Features: Seetec R3450 is a polypropylene-ethylene random copolymer designed for the production of cast films. It has a good clarity due to the optimum content of ethylene and offers optimum balance between optical properties and physical strength. It is suitable for the skin layer of co-extruded cast film in food packaging or semi retort pouch being required high slip and medium heat seal temperature. SEETEC R3450 meets the FDA requirement in the code of Federal Regulations in 21 CFR 177.1520 for food contact. Applications: CPP Film (High Slip) CAS No. 9010-79-1 Information provided by LG Chemical
