PROBLEM TO BE SOLVED: To provide a container for agricultural products, which is produced by using 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.
SOLUTION: The container for agricultural 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 1,400 &mum the polystyrenic expansion molded body has a density of 0.01 to 0.033 g/cm
3 the polystyrenic expansion molded body has an average chordal length of 20 to 150 &mum, and the polystyrenic expansion molded body has a bending strength of 20 to 100 N/cm2 .COPYRIGHT: (C)2011,JPO&INPIT
