Claims
- 1. A method of preparing a collection of thin thermoplastic interconnected bags comprising:
- (a) providing two separated thermoplastic films, each film being less than 0.75 mils and of at least approximately the same width and of a length suitable for the formation of one or more lengths of interconnected bags;
- (b) forming, transversely across each 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;
- (c) bringing said films together in face-to-face relationship with the lines of weakness across one film in registration with those of the other film;
- (d) sealing the films transversely along lines parallel with and immediately adjacent to the lines of weakness;
- (e) slit-sealing the film layers at one or more bag width intervals to complete individual but interconnected bag structures; and
- (d) collecting each strip of interconnected bags into a volumetrically efficient form.
- 2. The method of claim 1 wherein the lines of weakness in one film differs geometrically from the lines of weakness in registration therewith of the other film.
- 3. The method of claim 2 wherein the geometry of the line of weakness in one film of the bag includes a finger accommodating region.
- 4. The method of claim 1 wherein said interconnected bags are collected in a convolutely wound roll.
- 5. The method of claim 1 wherein each strip of interconnected bags is collected into an alternately folded bag arrangement to form a bad stack.
