Abstract
A shaping mold for forming a porous starch container includes a porous female mold which is breathable and is formed with a cavity; a porous male mold which is breathable; wherein the porous male mold contains a male mold plate and a protrusion; the protrusion extends from a bottom of the male mold plate; the porous male mold has at least one penetrating hole penetrating the male mold plate and the protrusion; and wherein when the porous male mold is combined to the porous female mold, a shaping space is formed between the protrusion of the porous male mold and the cavity of the porous female mold for forming a porous starch container; the shaping space is communicated to the penetrating hole. The starch material contains 50 wt %˜90 wt % (weight percentage) starch; 5 wt %˜25 wt % fiber enhancer; 3 wt %˜30 wt % CaCO3 for hardening; and may further contains 02 wt %˜5 wt % foaming material.
