Partitioned paperboard food tray

A paperboard package blank for erecting a divided tray shaped vessel, said tray having at least two distinct vessel sections separated by internal wall panels, wherein said blank is comprised of:

• a paperboard sheet material base having an interior surface lined with a continuous and unlapped layer of a blow molded polymer applied to said interior surface, wherein said base is formed into at least two bottom panel areas with each of said bottom panel areas being in the shape of a polygon having straight line perimeter segments delineated by first and second fold score lines such that said first and second fold score lines radiate in straight lines from a common point of termination;
• at least two internal wall panels materially integral with each of said bottom panel areas such that said first fold score lines are located substantially between said internal wall panels and each of said bottom panel areas, wherein said internal wall panels are substantially aligned along an internal wall edge that is substantially parallel to said first fold score lines;
• at least two external wall panels materially integral with each of said bottom panel areas such that said second fold score lines are located substantially between said external wall panels and each of said bottom panel areas;
• a top flange located adjacent to at least one of said external wall panels such that an external wall edge is located substantially between said top flange and said external wall panels, wherein said external wall edge is substantially parallel to said second fold score lines;
• a plurality of first side edges located substantially adjacent to said internal wall panels and radiating in substantially straight lines for a predetermined length from a terminus of said internal wall panels to said internal wall edge;
• and
• a plurality of second side edges located substantially adjacent to said external wall panels and radiating in substantially straight lines for a first length substantially corresponding to said first side edge length and continuing, at an angle to said first length, along a straight line to said top flange.
