Zippered film and bag

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.

1 . A method for making reclosable bags comprising:
 a. connecting a plurality of reclosable fasteners each with two interlocking profile strips to a rectangular sheet of film having two parallel side edges and a top and a bottom edge, each profile strip of each reclosable fastener means being maintained in the interlocked position and being independently connected to the same side of said film, said film being maintained in a flat unfolded state,   b. supplying a continuous sheet of said film with said reclosable fasteners and overlapping said side edges of said film to form a tube to enclose said reclosable fasteners on the inside of said tube, said tube having a top edge and a bottom edge,   c. sealing said overlapped side edges of said film,   d. sealing said bottom edge of said tube, and   e. sealing said tube said single bag length from said bottom edge to form a top edge of said bag to enclose a single reclosable fastener.
