    摘要： A method of producing a bag comprising the steps of:
    a) continuously feeding a web of plastics material along an apparatus from an input end thereof, the web having a reference mark printed thereon;
    b) operating a castellated rotary blade as the reference mark reaches a predetermined point to perform one of disengagement or engagement with the web, in order to define a perforated cut substantially parallel to the direction of feed;
    c) operating the rotary blade after a predetermined length of the web has passed the blade to perform the other of engagement or disengagement of the blade with the web, to define the perforated cut;
    d) cutting and welding the bag from the web, the bag having side edges substantially perpendicular to the direction of feed from the web;
    wherein the reference mark is located and the predetermined length is such that the perforated cut does not extend to either side edge.

    摘要： The present invention provides a packaging unit for hygiene articles and a method of forming a packaging unit, the unit being formed from a sheet of material having an inner surface, an outer surface and at least one folding axis dividing the sheet into a first region and a second region. The inner surface comprises an edge zone comprising an inner edge portion and an outer edge portion, wherein one of 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 of the inner edge portion and the outer edge portion of the edge zone of the second region is adhesive-free in a complementary manner to the edge zone of the first region. Thus, when the sheet is folded about the folding axis, the edge portions carrying adhesive in the first region are brought in contact with the adhesive-free edge portions in the second region, and the edge portions carrying adhesive in the second region are brought in contact with the adhesive-free edge portions in the first region.

    摘要： The present invention provides a packaging unit for hygiene articles and a method of forming such a unit. The packaging unit is formed from a sheet of material having an inner surface and an outer surface, wherein the inner surface comprises an edge zone comprising an inner edge portion and an outer edge portion. The sheet has at least one first folding axis, dividing the sheet in to a first region and a second region. One of the inner edge portion and the outer edge portion of the edge zone of the first region is provided with resealable adhesive, thus forming a first adhesive zone, 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, the inner edge portion or the outer edge portion of the edge zone of the second region corresponding to the adhesive-carrying edge portion of the first region is adhesive-free, such that when the sheet is folded about the first folding axis,the edge portions carrying resealable adhesive in the first region are brought in contact with the adhesive-free edge portions in the second region. A distance between the at least one first folding axis and the first adhesive zone is 1-20mm, preferably 2-18mm, more preferably 3-15mm.
