This invention is about a method of resin manufacturing and a resin which is decomposed in a short time by several kinds of microorganisms, a decomposable resin under this invention composes with carbohydrate polymer 20~64.5 wt % which has branch structures of amylose or amylopectin; hydrophilic resin 20~40 wt % which was mixed one or more than two of polyvinylalcohol, polyacrylic acid, polyethyleneacrylic acid; lublicant 5~20 wt % and thermoplastic resin 10~30 wt % and metal soap 0.5~5 wt % as stabilizer. Effects of the resin mixed under the above ratio are that the manufacturing method is simple and the cost of manufacturing is down, therefore, the consumer can get the cheaper one, furthermore this resin can be used for ordinary purposes as well as special purposes. |
