| 摘要 |
The invention relates to a film (55) which has a reclosable fastener (26) connected to one side of it, for making a bag having a reclosable fastener (26) connected to one wall. Attachment of the fastener to any other portion of the film (55) when making a bag is not required. The fastener (26) includes a tamper-proof member to indicate whether the bag has been previously opened. The film (55) can be wound into a roll (54) for use on conventional bag making machines including form, fill, and seal machines, or a chain of coilable reclosable bags can be produced since the fasteners (26) are connected to the web transversely to the longitudinal formation axis. The method and apparatus for making the film (55) include supplying a continuous web of material, feeding fastener material from a coil, positioning, cutting, and attaching the fastener (26) to the film (55), with a plurality of fasteners (26) attached thereon. <IMAGE> |
