<p>PROBLEM TO BE SOLVED: To prevent the moisture of contents of fill from transmitting through the wall of a container and volatilizing by a method wherein a biodegradable resin container is made by injection-blow-molding a biodegradable resin to which a plate-like additive is added. SOLUTION: This biodegradable resin container 1 is made by injection-blow- molding a biodegradable resin, in which a plate-like additive employing a mica- based inorganic matter cutting off transmitting courses in the wall 3 of the container. In this case, as that biodegradable resin, a polybutylene succinate- based resin, a copolymer of a butylene succinate and a butylene adipate, a copolymer of a hydroxybutylate and a hydroxybarillate, a polycaprolactam resin, a cellulose acetate-based resin, an aliphatic polyester such as a polyoxyacid including a polylactic acid or the like can be used. Thus, the moisture of contents to fill can be prevented from transmitting through the wall 3 of the container 1 and volatilizing.</p> |
