1. A composition for use in making biodegradable containers 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 the fibers comprise long fibers having a length of more than 4 mm and short fibers having a length of less than 0.5 mm;
wherein a dispersion of the composition is such that the fibers are substantially separated from one another throughout a starch based matrix;
a mold release agent;
a wax emulsion; and
a first protein or natural polymeric compound,wherein the composition consists essentially of food grade materials and is edible.
