PROBLEM TO BE SOLVED: To easily and reliably separate a web-like packaging film sheet in which packaging films are separably continuous at separation lines into each packaging film at the separation lines even in one in which adhesive agent coats the packaging film sheet along both sides thereof in the continuous direction and which is wound. SOLUTION: A separation line for separating a packaging film sheet 1 into each packaging film 3 consists of a perforation 5 and a micro sewing machine 6 having a tie part 5b shorter than a tie part 5b of the perforation 5. The micro sewing machine 6 extends from both sides in the continuous direction of the packaging film sheet 1 to an area forming the inner side from an affixing part 4 with a coating adhesive 4a.
