Abstract: A method for producing a diaper of the present invention includes the steps of: folding back a first strip-shaped portion 13 and a second strip-shaped portion 23; successively forming pairs of first and second belts 1 and 2 by cutting first and second separate webs W1 and W2; placing pairs of the first and second belts 1 and 2 at a predetermined interval P in a carrying direction Y of a continuous piece; temporarily attaching the first and second belts 1 and 2 to a portion of the continuous piece to be a back portion; fixing the belts 1 and 2 to the continuous piece; and severing the continuous piece with the belts 1 and 2 fixed thereon at a predetermined pitch into individual diapers.

Abstract: A method includes the steps of providing a tubing having an inner annular layer comprising a crosslinked polymeric material, and an outer annular layer comprising a non-crosslinked polymeric material, or a material that is crosslinked to a lesser extent than the material of the inner layer; longitudinally slitting the tubing to form a folded film; and reverse centerfolding the folded film to provide a folded film having a lateral slit edge, and a lateral folded edge opposite said lateral slit edge, such that the inner annular layer becomes an outer layer, and the outer annular layer becomes an inner layer. A bag can be made from the reverse centerfolded film, and an article such as food can be packaged in the bag.
