Abstract:
1. A fine paper powder-containing resin molded object made from a thermoplastic resin containing fine paper powder, comprising a non-foam layer formed on a surface and a foam layer formed in an inner side, wherein the fine paper powder-containing resin molded object contains 1 to 400 parts by weight of the fine paper powder finely pulverized from a raw material containing at least one of old paper selected from the group consisting of newspapers, magazines, wrapping papers, corrugated fiberboards, and office automation papers and having an average particle diameter ranging from 25 to 200 μm with respect to 100 parts by weight of the thermoplastic resin, the thermoplastic resin being at least one selected from the group consisting of polyethylene, polypropylene, polyester, polylactate, thermoplastic elastomer, polystyrene, and ABS resin, the foam layer is composed of, in the order from a side closer to the surface, a first foam layer containing cells having an average cell diameter ranging from 10 to 100 μm, a second foam layer containing cells having an average cell diameter which is smaller than the average cell diameter of the first foam layer and which ranges from 5 to 50 μm, and a third foam layer containing cells having an average cell diameter which is larger than the average cell diameter of the first foam layer and which ranges from 20 to 500 μm, and wherein the fine paper powder-containing resin molded object is free of wood powder.
