产品描述
Polypropylene 7450HC Low catalyst results in improved color stability.
Clarity/Impact: 7450HC improves its clarity and impact resistance over conventional homopolymer films.
Heat Sealable: 7450HC makes it suitable as a heat seal layer for oriented films.
Slip/Antiblock: 7450HC is formulated with a high level of antiblock additive for improved film handling.
FDA: 7450HC complies with all applicable FDA regulations for food contact applications.
Applications: 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: 7450HC resin processes on film extrusion equipment with typical melt temperatures of 450°F-525°F (232°C-274°C).
