There is provided an elongated sheet (10) for a medicine packaging bag, which prevents tear of cuts (b, 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. The sheet (10) is folded centrally in a width direction and a medicine (a) is introduced between its two-folded halves (11, 11). The sheet (10) is thermal-bonded (12, 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 (11, 11), thus forming the medicine packaging bag. A 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.
