Patent number: 9062190
Abstract: A stone based copolymer substrate includes calcium carbonate (CaCO3) from approximately fifty to eighty-five percent (50-85%) by weight and varying in size generally from 1.0 to 3.0 microns, high-density polyethylene (HDPE) from approximately two to twenty-five percent (2-25%) by weight and a biopolymer from approximately two to twenty-five percent (2-25%) by weight. The substrate may include a biodegradation additive from approximately three fourths of a percent to two percent (0.75-2%) by weight. By selectively adjusting the ranges of the substrate's components, various products can be made to replace current tree-based and plastic-based products. The substrate can be configured to be tear proof, water proof, fade resistant and fire retardant while utilizing less energy and producing less waste during its manufacture. In an exemplary embodiment of the invention, the stone used in the substrate includes limestone.
