    • A process for manufacturing reclosable bags (30) by forming a film (50) includes moving the film (50) and attaching to the film (50) sequentially and crosswise with reference to the direction of movement of the film (50), a fastener (1) including a first strip (2) supporting at least one reclosable profile (10) engaged with another reclosable profile (12) that is complementary thereto and supported by a second strip (4) or a part of the first strip (2), which will subsequently be attached to the film (50). Each strip (2, 4) includes at least one web (6, 8) extending substantially mostly sideways on one side of the profiles (12). The above arrangements make possible special fasteners (1) that include sliders (9), gasket membranes (26), fasteners inverted within the bag (30), peel seals (18, 20, 21) and hinged fasteners (1).
    • 通过形成膜(50)制造可再封闭袋(30)的方法包括相对于膜(50)的移动方向依次和横向地移动膜(50)并附着到膜(50)上,紧固件 (1)包括支撑至少一个可再闭合型材(10)的第一条带(2),所述第一条带与另一个与其互补并由第二条带(4)或第一条带(2)的一部分支撑的可再闭合型材(12) ,其随后将附接到胶片(50)。 每个条带(2,4)包括在轮廓(12)的一侧上基本上主要侧向延伸的至少一个腹板(6,8)。 上述布置使得可能的特殊紧固件(1)包括滑块(9),垫圈膜(26),在袋(30)内翻转的紧固件,剥离密封件(18,20,21)和铰链紧固件(1)。
