CA 2425465

A method for making molded packing shapes comprising rite sequential steps: (1) forming a plurality of particles comprising a foamed admixture of starch, biodegradable polymer and water, (2) applying to the surface of the particles an unheated aqueous liquid to effect wetting and softening of the surfaces of the particles; and (3) without applying extraneous heat to the system, compressing the surface-softened particles within a confined spar to effect cohesion between the surfaces of the softened particles and formation of an article in the form of the confined space; and (4) maintaining the shaped article under such compression for a tune sufficient to render the surface of the particles non-tacky by adsorption of the wetting liquid into the particles and by evaporation of the wetting liquid.
