Total PPR 7450HC Polypropylene, Film Extrusion Grade
Categories:	Polymer; Film; Thermoplastic; Polypropylene (PP); Polypropylene, Film Grade
Material Notes:	Random copolymer heat sealable film grade Color - Low catalyst residuals in FINA 7450HC result in improved color stability. Clarity/Impact - The random copolymer structure of FINA 7450HC improves its clarity and impact resistance over conventional homopolymer films. Heat Sealable - The reduced melting point of FINA 7450HC makes it suitable as a heat seal layer for oriented films. Slip/Antiblock - FINA 7450HC is formulated with a high level of antiblock additive for improved film handling. FDA - FINA 7450HC complies with all applicable FDA regulations for food contact applications. Recommended Applications - FINA 7450HC is recommended for use in either non-oriented cast film processes for manufacture of packaging films that require improved optical and impact properties or as a heat seal layer for oriented films. Processing - FINA 7450HC resin processes on film extrusion equipment with typical melt temperatures of 450-525°F (232-274°C). Data provided by the manuf Total Petrochemicals acquired former Fina and Atofina plastics product lines.
