Material Notes:
Features: Seetec R3420 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 general purpose of coextruded cast film in food packaging or semi retort pouch being required non slip and medium heat seal temperature. SEETEC R3420 meets the FDA requirement in the code of Federal Regulations in 21 CFR 177.1520 for food contact. Applications: CPP Film (Non Slip)CAS No. 9010-79-1Information provided by LG Chemical
