ABSTRACT:
A pulp molding is formed by molding a feedstock consisting of, as principal components, pulp and some binder. The feedstock contains plastic microspheres which form uniformly distributed voids in the pulp molding. The pulp molding has cushioning characteristics higher than those of the conventional pulp molding and equivalent to those of a foam styrene board, and moisture absorbing characteristics lower than those of the conventional pulp molding. The pulp molding can be deflocculated in water for reclamation without causing environmental pollution.
