ABSTRACT:
Lids and/or closures applied to cartons which are used for distributing, marketing and heating small portions of prepared food are fabricated with a paperboard structural substrate coated with a heat activated (or sealable) coating of water soluble acrylic emulsion that is applied by means of a press in conjunction with a printing operation or, alternatively, by a coating operation separate from the printing operation. Other critical coating characteristics are that the acrylic emulsion coating is heat sealable to itself, to polymers such as polyethylene terephthalate and directly to unprimed paperboard, with or without a clay coating, and can be tack bonded at temperatures of 250.degree. F. or greater. Additionally, so as to avoid food contamination from the coating, the coating is mass stable below 400.degree. F. and have chloroform-soluble extractives not exceeding 0.5 mg/in.sup.2 of a food contact surface when exposed to a food simulating solvent, (for example, N-Heptane) at 150.degree. F. for two hours.
