All clear for packaging.

Marlex BP546 polypropylene, a clarified 12-melt flow homopolymer, offers molders a reported 50% improvement in clarity for packaging applications. It is especially recommended for packaging of ready-prepared foods that can go from the freezer to the microwave and for hot-filled containers.

Particularly suitable for making bottles by injection-stretch blowmolding, the resin meets FDA regulation 21 CFR 17.1520 and can be used in contact with alcoholic beverages containing less than 20 wt% alcohol. As a general-purpose injection molding resin it is useful for deli containers, cosmetics packaging, housewares, closures, and toys.

For optimum part quality and clarity, processing recommendations include stock temperature at 425|degrees~F |+ or -~ 10|degrees~F and mold temperature of 90|degrees~F to 110|degrees~F. Key properties include density of 0.914 g/cc, melting point of 329|degrees~F, tensile strength of 5500 psi, and an unnotched Izod of 15 ft-lb/in.
