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 thereofwhich 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 tothe 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 makea single fastener, ( 26 ) positioning, cutting, and attaching the fastener ( 26 ) to the film ( 55 ), with a plurality of fasteners ( 26 ) attached thereon.
