Abstract

Foil bags are formed as new paper bags by fusing together two webs and tying a detachable strap which has a suspension opening to one said opening of each bag, the strap being separated by a perforation line from the respective side of the bag. A pocket is formed at the end of the bag opposite the insertion opening and can have a flap provided with an adhesive strip covered by a masking layer.
