BFI 8473 Cast P/P Film Properties

Polypropylene 8473 is a low melting, high ethylene random copolymer with improved color, optics and impact properties.

Heat Sealable: The very low melting point of 8473 makes it an excellent heat seal layer for oriented films.

Slip/Antiblock: 8473 is available with custom slip and antiblock packages.

FDA: 8473 complies with all applicable FDA regulations Title 21 CFR Section 177.1520(c) 3.1 and may be used under these provisions for food contact and packaging.

Recommended Applications: 8473 is recommended for use in non-oriented film processes for manufacture of packaging films that require improved optical and impact properties and as a heat seal layer for oriented films.

Processing: 8473 resin processes on film extrusion equipment with typical melt temperatures of 390ºF - 450ºF (199ºF - 232ºC).
