Abstract
The present invention relates to a collection of ultra-thin bags and a collection of bags per se wherein said bags are made by providing two separated thermoplastic films; forming transversely across each separated film, lines of weakness extending from one edge of each film to the other, with each line spaced from the next a bag length distance apart; bringing the films together in face-to-face relationship with the lines of weakness across one film in registration with those of the other films; sealing the films transversely along lines parallel with and immediately adjacent to the lines of weakness; slit-sealing the film layers at one or more bag width intervals to complete individual but interconnected bag structures; and collecting each strip of interconnected bags into a volumetrically efficient form.
