Abstract (en)

A method of making a bag comprises providing a plurality of lengthwise extending folds (84) in a web (56) of flexible packaging material and positioning a length of flexible material (114) on the folded web. The length of material (114) is attached to the web (56) at positions spaced from the folds, by seals (24), caused to adopt a tubular configuration, and then sealed to form a tube. The tube is then sealed transversely to define a bag. The length of material is attached to the inside of each upright face of the finished bag and provides a strengthening ring for the bag. <IMAGE>
