A packaging unit for hygiene articles is formed from a sheet of material having an inner surface and an outer surface. The inner surface includes an edge zone including an inner edge portion and an outer edge portion. The sheet has at least one folding axis dividing the sheet into a first region and a second region. The inner edge portion and the outer edge portion of the edge zone of the first region is provided with adhesive, and the other of the inner edge portion and the outer edge portion of the edge zone of the first region is adhesive-free. Further, one of the inner edge portion and the outer edge portion of the edge zone of the second region is provided with adhesive, and the other is adhesive-free in a complementary manner to the edge zone of the first region.

A gusset bag is formed of a pair of flat surface parts facing each other, and side gusset parts folded to the inside of the bag. The gusset bag has side heat-sealing portions at which the sides of the flat surface part and sides of the side gusset parts are joined at the inner surfaces thereof, side heat-sealing portions at which the sides of the flat surface part and the other sides of the side gusset parts are joined at the inner surfaces thereof, and closing sealing portions at which the side heat-sealing portions and the side heat-sealing portions are joined at the outer surfaces of the side gusset parts by ultrasonic sealing. With this configuration, in the gusset bag, it is possible to easily close the gusset parts, while preventing film pieces or dust from entering the bag in a step of closing the gusset parts.

A flexible film, and articles comprising the film, comprises interleaved pluralities of each of first bands and second bands disposed adjacent to the first bands. Both the first and second bands have a length and a width; the first bands comprise a first film basis weight and first and second regions. The first regions and second regions being comprised of the same material composition. The first regions undergo a substantially molecular-level deformation and the second regions initially undergo a substantially geometric deformation when the sheet material is subjected to an applied elongation along at least one axis. The second bands comprise a second film basis weight and a plurality of corrugations disposed along the length of the band. In this aspect the material may be described as having alternating bands of structural-elastic-like film and ring-rolled film.

A woven laminated plastic bag having an easy open feature is provided. The easy open feature is generally defined by a weakened portion in the bag. In various aspects the bag can be fabricated from a woven polyethylene layer which can be laminated with a polyethylene film layer, can form a pinch bottom bag, and can have one or both sides include graphics and/or printing. The bag can also provide a top end and/or a bottom end either or both of which provide a discrete area which may contain discrete graphics and/or printing.

A method of producing flexible polypropylene fabric bags with heat fused seams comprising providing fabric pieces, wherein each fabric piece has a coated side and an uncoated side; positioning fabric pieces so that a coated side of one fabric piece faces a coated side of another fabric piece; selecting an area of fabric to be joined for forming a seam or joint; applying heat to the area to be joined that is less than the melting point of the fabrics, for forming one or more seams or joints and wherein the heat fused seams or joints of a resulting polypropylene bag retains at least 85% of the fabric strength without using sewing machines.

A woven laminated plastic bag having an easy open feature is provided. The easy open feature is generally defined by a weakened portion in the bag. A cover may cover the weakened portion and may be opened by pulling on a pull tab. In various aspects the bag can be fabricated from a woven polypropylene or polyethylene layer which can be coated or laminated with a polypropylene or polyethylene film layer, can form a pinch bottom bag, a block bottom bag, and can have front, back, side, and top and bottom panels that may have high quality graphics and/or printing.

The invention relates to an inflatable pouch comprising an inflatable pouch with an interior pocket; an air valve attached to the inflatable body; a zipper configured to close an opening of the inflatable body; at least one clasp attached to the pouch; a rope connecting each clasps of the at least one clasp; a rope adjuster attached to the rope; and at least one ring attached to each clasp of the at least one clasp. The invention also relates to a method for creating an inflatable pouch.
