PROBLEM TO BE SOLVED: To provide white paperboard for a paper container that has at least two layers by multilayer paper making, includes bleached wood pulp at a high blended rate in a surface layer and a back layer, is for single side printing, and does not cause a problem of a backing fuzz, and to provide a paper container obtained from the white paperboard.SOLUTION: There is provided a method for producing a white paperboard for a paper container that has at least two layers by multilayer paper making, includes bleached wood pulp at a high blended rate in a surface layer and a back layer, and is for single side printing. In the method, a starch solution coating is performed twice, or a starch solution coating is performed and then a water coating is performed, or a water coating is performed and then a starch solution coating is performed, on a non-printing surface. It is preferable that the total coating weight of the starch on the non-printing surface is set to be 0.5 to 4.0 g/min terms of solid content, and drying by a dryer is performed between the first and the second coating and after the second coating. |
