Therefore the strength of a recycled container can be held. The strength of the recycled container is held also by setting the upper limit of a charging ratio of the recycled resin according to the measured strength. Moreover, the recycled container having an excellent outward appearance can be provided, since the recycled container of a sandwich structure having a core layer of the recycled resin and a surface layer of an unused resin is molded. <P>COPYRIGHT: (C)2004,JPO</p> |
