  • Method of making an elastic film, in particular for a hygienic article
    Patent number: 8648139
    Abstract: An elastic film for a hygienic article is made by first premixing polymer components to form a polymer composite that contains styrene block copolymers and then extruding the polymer composite to make at least one layer. During the premixing or the extruding zeolites are added having pores of a size larger than 2.5 Angstrom and smaller than 5.5 Angstrom.
    Type: Grant
    Filed: December 16, 2010
    Date of Patent: February 11, 2014
    Assignee: Mondi Gronau GmbH
    Inventor: Mike Rolefs
  • Diaper closure and method of making same
    Patent number: 8496773
    Abstract: A laminated web from which diaper closure elements may be punched is made by first applying at least two pairs longitudinally extending and transversely spaced bend-resistant strips to a first longitudinally extending nonwoven tape. Then a respective longitudinally extending strip of an elastically stretchable polymer is applied to the first nonwoven tape between each of the pairs of the bend-resistant strips with the polymer strip partially overlapping both of the bend-resistant strips of the respective pair. A second longitudinally extending nonwoven tape that covers and extends transversely to both sides of the polymer strip is applied over the bend-resistant strips and the polymer strips to form a laminate with the polymer strip between the first and second nonwoven tapes.
