Abstract:
1. A composition for use in making a biodegradable and microwavable food container comprising: water; starch, wherein the starch comprises pregelatinized and native starch and wherein the pregelatinized starch is in a range from more than 0% to less than 30% by weight of the total starch in the composition; fibers, wherein a dispersion of the composition is such that the fibers are substantially separated from one another throughout a starch based matrix; and a metal or metal oxide, wherein the metal or metal oxide is substantially dispersed throughout the composition such that the metal or metal oxide is partially or substantially enveloped by the starch of the starch based matrix to prevent sparking when microwaved and wherein the metal or metal oxide is in a range from more than 0% to less than 25% by dry weight of the composition wherein the dry weight of the composition is the total weight of the non-water components thereof.
