A block of bags formed from a stack (20) of bags, each bag formed from a tubular bag body. The bag body includes lateral side edges (40, 42) and a top edge (46), a first line of perforations (52) extending perpendicularly from one lateral edge of the bag body, and a second line of perforations (54) extending perpendicularly from an opposite lateral edge of the bag body. The first and second lines of perforations are spaced at a first distance from the top edge of the bag body. First and second cuts extend from an end of the first and second lines of perforations respectively toward the top edge of the bag body. The first and second lines of perforations and the first and second cuts define tear off regions (60) at the corners of the bag body. First and second unitizing holes penetrate through the stack of bags within the first and second tear off regions respectively to unitize or block the stack. |
