PROBLEM TO BE SOLVED: To provide a waste treatment bag capable of shortening time required for waste water treatment.SOLUTION: A waste disposal bag 10 includes: a bag-shaped water-soluble film 2 in which a front side panel 21 and a back side panel 22 are continuous in a folded state at a bottom and at least a part thereof is joined at a side portion and a water-dispersible paper 3 in which a front side panel 31 and a back-side panel 32 are continuous in a folded state at the bottom and are disposed outside the water-soluble film 2. The water-soluble film 2 and the water-dispersible paper 3 are separated from each other at bottom folded-back portions 23, 33 of both of them and joined at a portion other than the bottom portion. The water-soluble film 2 has a film-side upper opening (upper opening 24) opened on the opposite side to the bottom and a film-side auxiliary opening (auxiliary opening 41) opened in a portion other than the upper opening 24.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】排水処理時の時間を短縮することが可能な汚物処理袋を提供することにある。【解決手段】汚物処理袋10は、表面側パネル21と裏面側パネル22とが、底部において折り返し状に連続し、かつ、側部において少なくとも一部が接合された、袋状の水溶性フィルム2と、表面側パネル31と裏面側パネル32とが底部において折り返し状に連続し、水溶性フィルム2の外側に配置された水分散性の紙3と、を備えており、水溶性フィルム2と水分散性の紙3とは、両者の底部折り返し部23,33において互いに分離しているとともに、底部以外の部位において接合されており、水溶性フィルム2は、底部とは反対側に開口したフィルム側上部開口部(上部開口部24)、および、上部開口部24以外の部位において開口したフィルム側補助開口部(補助開口部41)を有することを特徴とする。【選択図】図1
