PROBLEM TO BE SOLVED: To provide a new resin molded article which has excellent transparency and excellent mechanical strengths, to provide a resin molded article which can be separated in water by the utilization of specific gravity, and further to provide a resin molded article which has moistureproofness suitable as a packaging material and especially thermal shrinkage characteristics sufficient as a shrink film. SOLUTION: This resin molded article comprising at least one cyclic olefinic polymer selected from (A) the polymer of a vinylalicyclic hydrocarbon compound or the copolymer of the compound with a copolymerizable monomer, (B) a polymer obtained by hydrogenating at least 30% of the aromatic rings of the polymer of a vinylaromatic hydrocarbon compound or a copolymer obtained by hydrogenating at least 30% of the aromatic rings of the copolymer of the compound with a copolymerizable monomer, (C) the polymer of a monocyclic monoolefin compound or the copolymer of the compound with a copolymerizable monomer, and (D) the hydrogenation product of the polymer of a monocyclic conjugated diene compound or the hydrogenation product of the copolymer of the compound with a copolymerizable monomer.
