A corrugated plastic box and a method for manufacturing a corrugated plastic box from a blank are provided. The method includes the steps of forming rounded edge seals on the perimeter edges of the blank, pre-sealing portions of the blank to form a plurality of areas in which major and minor flap slots and a glue tab are desired, ultrasonically scoring the blank to form a plurality of flap score lines, and cutting the blank through the plurality of pre-sealed flap slots and glue tab, leaving a sealed edge.

A container for the shipment and display of a food product includes a four-sided, collapsible, corrugated plastic sleeve that is selectively enclosed by a pair of opposing plastic trays. Each tray includes inner and outer flanges which are formed along the periphery of a planar plate in a spaced apart relationship and together define a continuous groove dimensioned to receive an open end of the sleeve. The inner flange includes a tapered interior surface which widens the groove towards its distal end to facilitate the process of aligning and inserting an open end of the sleeve therein. A series of projections, each semicircular in lateral cross-section, are formed onto the outer flange and are dimensioned to fittingly protrude through corresponding slots formed in the sleeve to retain the container in its assembled state during the process of packaging and transporting the designated product.

The invention is directed to straight, consistent body scores on plastic corrugated boxes and a process for making the body scores.
