Abstract
A blow-molded plastic container manufactured from a homogenous mixture of a plastic resin, a calcium carbonate filler, and a blowing agent in specified amounts. The filler reduces the overall material costs, and the blowing agent reduces the specific gravity of the mixture to enable the container to be recycled utilizing existing floatation tank recycling equipment.
