Abstract (en)
[origin: US2011019944A1] A system including multiple bags each having a first adhesive material on a first panel, and second adhesive material on a stepped construction of the bag, and a third section of each bag being free of adhesive, further including a hot air manifold along which the bag is conveyed after the bag has been filled with contents and closed, which heats the first adhesive material and the second adhesive material to their adhesive states; a section of the hot air manifold along which the third section free of adhesive is conveyed, which minimizes adhesive contamination; a blade to bias the stepped construction of the bag to follow along the manifold; and a trailing end of the blade to fold the bag along its third section without displacing or expelling adhesive from the third section, which minimizes adhesive contamination of surfaces of the bag.
