Abstract
This relates to the blow molding of containers wherein the containers are formed of biaxially oriented plastic material. A multi-sided hollow member is blown within a convention blow mold using a conventional type of preform. Each side, when severed from the top and bottom of the hollow member and from each other forms a tray or box like container having a bottom, side walls and a peripheral sealing flange. The efficiency of the container from a weight to capacity standpoint is at a maximum due to the biaxial orientation of the plastic material.
