Claim:
A reclosable bag comprising: a bag body having two opposing side walls joined along three edges to form therebetween a pouch having an open end; and a closure strip permanently attached to the two side walls of the bag body along the open end, the closure strip comprising a sheet-form resin substrate having a front face and a back face; an array of loop-engageable fastener elements with stems integrally molded with and extending from the front face of the substrate and forming a discrete band of fastener elements extending longitudinally along the length of the closure strip; and a loop strip carried on the front face of the substrate and forming a discrete band of engageable loops extending along the length of the closure strip and spaced apart from the band of fastener elements, the loop strip arranged to be engaged by the array of fastener elements to releasably retain the bag in a closed condition; wherein the substrate of the closure strip defines at least one frangible region extending longitudinally along the length of the closure strip between the band of loops and the band of fastener elements, for tearing the substrate between the loops and the fastener elements to open the bag, the frangible region comprising an embedded, longitudinally continuous filament adapted to be torn from the closure strip to tear the substrate along the frangible region.
