<p><P>PROBLEM TO BE SOLVED: To provide a container for marine products, which uses expandable styrenic resin particles suppressing falling-off of a coating agent in a circulation process to a pre-expanding machine, a silo or an expansion molding machine, and exhibiting very little adhesion of the coating agent to the inner surface of a particle circulation pipe. <P>SOLUTION: The container for marine products includes a polystyrenic expansion molded body obtained by pre-expanding expandable styrenic resin particles obtained by impregnating an expanding agent in styrenic resin particles, and molding the pre-expanded particles, wherein the expandable styrenic resin particle is coated on the resin particle surface with a composition; the composition is composed of a polyhydric alcohol A which is to coat the resin particle surface and is liquid at normal temperature, 0.01-0.3 pts.wt. of a fatty acid monoglyceride with respect to 100 pts.wt. of the resin particle, 0.03 to 0.3 pts.wt. of a fatty acid metal salt with respect to 100 pts.wt. of the resin particle, and a polyhydric alcohol B which is liquid at normal temperature; the polyhydric alcohols A and B are contained in 0.02 to 0.3 pts.wt. with respect to 100 pts.wt. of the resin particle; and the composition is coated in two installments, and wherein the polystyrenic expansion molded body is a polystyrenic resin particle having a particle diameter of 600 to 1,400μm; the polystyrenic expansion molded body has a density of 0.01 to 0.033 g/cm<SP>3</SP>; the polystyrenic expansion molded body has an average chordal length of 20 to 150μm, and the polystyrenic expansion molded body has a 5%-compression strength of 5 to 30 N/cm<SP>2</SP>. <P>COPYRIGHT: (C)2011,JPO&INPIT</p> |
