PROBLEM TO BE SOLVED: To provide an elongated sheet 10 for a medicine packaging bag, which prevents tear of cuts b and 16 caused by a tension during travel of the sheet etc. and which allows a medicine packaging bag A to easily tear and thus open.SOLUTION: The sheet 10 is folded centrally in a width direction and a medicine a is introduced between its two-folded halves 11 and 11. The sheet 10 is thermal-bonded 12 and 13 along an entire width ahead of and behind the medicine a and along an entire length of open edge portions of the two-folded halves, thus forming the medicine packaging bag. The thermal-bonded portion 13 in the open edge portions is formed inwardly. A large number of fine tearing cuts 16 (4 mm width) are formed inwardly from an end edge 17 of the open edge portions by 1 mm between the thermal-bonded portion 13 and the open edge portions along an entire length in a longitudinal direction of the sheet 10. A tearing cut-less portion 18 is formed between the cut portion and the end edge 17 of the open edge portions. Due to the presence of the tearing cut-less portion 18 (1 mm width), tear caused by the tension through the cut does not occur and the sheet can be smoothly drawn out. Further, the bag can be easily torn due to the cut portion.COPYRIGHT: (C)2014,JPO&INPIT【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
