Abstract

Disposable food contact compatible microwaveable containers having at least one micronodular surface are disclosed. These containers including plates, bowls, cups, trays, buckets, soufflé dishes, and lids are prepared from polypropylene or propylene-ethylene copolymer or blends, talc and mica mixtures and pigment and are thermoformed into the shape of the aforementioned articles of manufacture exhibiting (a) a micronodular surface on at least one side; (b) a melting point of not less than about 250°F;
said articles of manufacture being dimensionally stable and resistant to grease, sugar, and water at temperatures up to at least 250°F and being of sufficient toughness to resist cutting by serrated polystyrene flatware.
