This provides a pair of funnel strips each of which has a series of funnel pockets at its edge along the line. Bag body wall sheets attached to the panels are arranged to receive the funnel pockets of each strip in inwardly extending relation therebetween, for providing respective reversible funnels in bags into which the strips and bag wall sheets are adapted to be divided. The panels may carry separable fastener profiles adjacent their edges remote from the zig-zag line.
