Total 7476CA Polypropylene, Film Extrusion Grade  (discontinued **)
Categories: Polymer; Film; Thermoplastic; Polypropylene (PP); Polypropylene, Film Grade
Material Notes: Random copolymer heat sealable film grade

Color - Low catalyst residuals in FINA 7476CA result in improved color stability.

Clarity/Impact - The random copolymer structure of FINA 7476CA improves its clarity and impact resistance over conventional homopolymer films.

Heat Sealable - The reduced melting point of FINA 7476CA makes it suitable as a heat seal layer for oriented films.

Slip/Antiblock - FINA 7476CA is formulated with a custom slip and antiblock packages for improved film handling.

FDA - FINA 7476CA complies with all applicable FDA regulations for food contact applications.

Recommended Applications - FINA 7476CA 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 - FINA7476CA resin processes on film extrusion equipment with typical melt temperatures of 450-525°F (232-274°C).
