Claims
- 1. A method of producing a stack of plastic foil bags each of which comprises a flap projecting beyond a filling opening on one broad side of the respective bag, each of said bags having a corner tear-off segment formed by a region delimited by a row of perforations and formed in said corner region with at least one interlocking point joining said bags in said stack and a stack-incorporation means separate from said interlocking point and enabling assembly of said bags into said stack, said method comprising the steps of:folding a plastic foil web to provide broad surfaces of respective bags with flaps extending from one of the broad surfaces; perforating corner portions of said flaps to form tear-off segments along an arcuate perforation line; forming cross-slits in each of said tear-off segments near the respective perforation line; engaging pins in said slits to stack said bags together; and securing the stacked bag together within the tear-off segments.
- 2. A stack of plastic foil bags each having a flap projecting beyond a filling opening on one broad side of the respective bag, each of said bags having corner regions of the respective flap delimited by an arc-shaped row of perforations and being formed in the respective corner region with at least one interlocking point joining said bags in said stack and a stack-incorporation means separate from said interlocking point for enabling assembly of said bags into said stack and disposed close to the respective row of perforations said stack-incorporation means being each located at an inwardly pointing area of the respective corner region.
- 3. The stack defined in claim 2 wherein said stack-incorporation means are offset toward the outer margin of the respective flap with respect to a median line connecting the interlocking points.
- 4. The stack defined in claim 2 wherein said stack-incorporation means include holes punched through said bags.
- 5. The stack defined in claim 2 wherein said stack-incorporation means are cross slits.
- 6. A stack of plastic foil bags each having a flap projecting beyond a filling opening on one broad side of the respective bag, each of said bags having a corner region delimited by a row of perforations and formed in said corner region with at least one interlocking point joining said bags in said stack and a stack-incorporation means in the form of slits separate from and inwardly of the respective interlocking point and enabling assembly of said bags into said stack.
- 7. The stack defined in claim 4 wherein said stack-incorporation means are cross slits.
