    • 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.
    • 要解决的问题:为了提供用于药物包装袋的细长片材10,其防止由片材等行进期间的张力引起的切口b和16的撕裂,并且允许药物包装袋A容易撕裂并因此打开 。解决方案:片材10在宽度方向上中心折叠,并且药物a被引入其两个折叠的半部11和11之间。片材10沿着药物a前面和后面的整个宽度热粘合12和13 并且沿着两折半部的开口边缘部分的整个长度,从而形成药物包装袋。 开口边缘部分中的热接合部分13向内形成。 在开口边缘部分的端部边缘17之间沿着热接合部分13和开口边缘部分之间沿着纵向方向的整个长度方向向内形成大量细小的撕裂切口16(宽度4mm) 在开口边缘部分的切割部分和端部边缘17之间形成有撕裂切割部分18。 由于存在撕裂切断部18(1mm宽),不会发生通过切割的张力引起的撕裂,并且片材能够顺利地拉出。 此外,由于切割部分,袋可以容易地撕裂。
