ABSTRACT:
Reclosable bags, plastic film for making the bags, and a method and apparatus for making the bags are disclosed. The bag has a reclosable fastener (26) connected to a single wall of the bag, and the film (55) has a reclosable fastener (26) connected to one side thereof which does not require attachment to any other portion of the film (55) when making a bag. The fastener (26) has a tamper-proof member attached thereto to indicate if the bag has been previously opened. The film (55) can be wound into a roll (54) suitable for use on conventional bag making machines including form, fill, and seal machines or a chain of coilable reclosable bags can be produced therefrom since the fasteners (26) are connected to the web preferably transversely to the bags longitudinal formation axis. The method and apparatus for making the film (55) includes supplying a continuous web of bag making material, feeding from a coil of continuous fastener material enough fastener material to make a single fastener, (26) positioning, cutting, and attaching the fastener (26) to the film (55), with a plurality of fasteners (26) attached thereon.
