ABSTRACT:
There is disclosed herein a flexible bag in which the back panel is defined by inner and outer overlapping sections that overlap to form a back seam. The outer section defines a removable section which has a first perforation generally parallel to the back seam and an edge that is generally parallel to the bag bottom and intersects the first perforation. Alternatively, a second perforation may be provided along the edge. The outer panel is about as wide as the bag and the removable section is less than one-half the width of the outer panel. The first perforation is positioned between the back seam and side edge of the removable section. The first perforation may be adjacent the back seam and the second perforation is adjacent the bag bottom.
A blank for forming said bag from a web is also disclosed.
