While preventing salmon, scar 16 b by the tension of the running time of 10 (challenge) drug packaging bags for elongated sheet, to obtain the effect of the open tear their ease of drug packaging bag A. In folding the width direction center (SOLUTION) sheet 10, was charged with a drug during the two pieces 11 and 11 folded, two pieces of folded and the full width of the front and rear of a drug in the sheet 10 It is a drug packaging bag was heat-sealed 12, 13 the opening edge length. To form inside the opening En-netsu fused portion 13, from the heat-sealed portion 13 during part of the opening edge, fine scars tear a number of over the direction of the full-length length of the sheet 10 (width 4mm) 16 , by forming the 1mm inward from the edge 17 of the opening edge, to form the portion 18 that there is no scar portion between the edge 17 of the opening edge portion and the scar area. The presence of (1mm wide) 18, also does not cause tearing through scar by the tension part without that scar portion, can be performed smoothly pulled out of the sheet. On the other hand, by section scar, I can tear easily. [Selection] Figure Figure 1(課題)薬剤包装袋用長尺状シート10の走行時等の張力による傷痕b、16の裂けを防止しつつ、その薬剤包装袋Aの容易な引き裂きによる開放効果を得る。(解決手段)シート10をその幅方向中央で折り重ね、その折り重ねた2片11、11の間に薬剤aを投入し、シート10の薬剤aの前後の全幅及び前記折り重ねた2片の開口縁部全長を熱融着12、13した薬剤包装袋である。開口縁熱融着部13を内側に形成し、その熱融着部13から開口縁部の間部分に、シート10の長さ方向全長に亘る多数の微細な引き裂き用傷痕(幅4mm)16を、開口縁部の端縁17から1mm内側に形成して、その傷痕部と開口縁部の端縁17の間にその傷痕部がない部分18を形成する。その傷痕部がない部分(1mm幅)18の存在によって、前記張力による傷痕を介した引き裂きも生じず、そのシートの円滑な引き出しを行い得る。一方、傷痕部によって、容易に引き裂きし得る。【選択図】図1
