Abstract | To provide a laminated film roll capable of suppressing occurrence of winding deviation of and wrinkles in a lead section even when an adhesive layer is provided on a base material film.SOLUTION: In a laminated film roll 11, a laminated film 13 includes: a base material film 14; an adhesive layer 15 provided on one surface side of the base material film 14; and a functional film 16 having a predetermined pattern and bonded to one surface side of the base material film 14 by the adhesive layer 15. A lead portion P2 indicating a terminal end of the laminated film 13 by the non-disposition of the functional film 16 is provided at an end portion of a beginning edge of the laminated film 13 relative to a winding core 12. The lead portion P2 is separated from a beginning side edge 13a by a body portion P1 where the functional film 16 is disposed.SELECTED DRAWING: Figure 5
【課題】基材フィルムに粘着層を設ける場合であっても、リード部分の巻ずれや皺の発生を抑制できる積層フィルム巻回体を提供する。【解決手段】積層フィルム巻回体11では、積層フィルム13は、基材フィルム14と、基材フィルム14の一面側に設けられた粘着層15と、所定パターンを有し、粘着層15によって基材フィルム14の一面側に接合された機能フィルム16と、を有し、巻芯12に対する積層フィルム13の巻き始め側の端部には、機能フィルム16が配置されないことで当該積層フィルム13の終端を示すリード部分P2が設けられており、リード部分P2は、機能フィルム16が配置された本体部分P1によって、巻き始め側の縁13aから離間している。【選択図】図5 |
