  • Patent number: 7553530
    Abstract: A waved mesh tube including multiple parallel first strings spirally extending in a first direction and multiple parallel second strings spirally extending in a second direction. The second strings are laid on the first strings. The mesh tube has continuous circles of waved bending sections arranged along an axis of the mesh tube. The mesh tube is formed with the bending sections so that the wall of the mesh tube has multiple wave crests and wave troughs adjoining each other. The wave troughs define an inner diameter of the mesh tube, while the wave crests define an outer diameter of the mesh tube. Each of the wave crests and the wave troughs has an acute angle. A difference between the inner diameter and the outer diameter is a thickness of the wall of the mesh tube. The wall of the mesh tube is waved and solid and has higher rigidity.

  • Publication number: 20090061130
    Abstract: Method for shaping a material with a reticular structure, plant for performing same and reticular material resulting from the method. This method is applicable for handling a reticular tubular structure, in particular one of those obtained by extruding a synthetic plastics material, wherein its filaments, which form the sides of the net mesh, have a greater thickness at the crossover points than the actual thickness of the filaments. This method consists in the synthetic plastics material with a reticular tubular structure being subjected, while hot and with its tubular flattened shape, to two-dimensional molecular orientation operations, through drawing and widening, followed by an operation to equal the thicknesses of the reticular tubular flattened structure, already oriented, by laminating it in a calendering machine.

  • Patent number: 6689437
    Abstract: An oxygen-absorbing material including a transition metal compound and one or more thermoplastic resins, when used for a molded product such as container, exhibits excellent gas-barrier and oxygen-absorbing properties. The material absorbs oxygen from contents and blocks oxygen from entering so that the contents can be maintained in an oxygen-free state for a long period of time. An excellent oxygen-absorbing property is achieved by an amino group content of 20 mmol/kg or lower in at least one thermoplastic resin and by lowering the crystallinity of the thermoplastic resin.

  • Patent number: 6596355
    Abstract: A packaging material is composed of a heat resistant base layer, a sealant layer, and a resin layer disposed at least a portion between the heat-resistant base layer and the sealant layer. The resin layer is composed of a resin material having a predetermined strength in a non-heated temperature state of less than a room temperature and this strength is lowered in a high temperature state heated, for example, by a microwave oven. Such packaging material can be effectively utilized for many kinds of packaging bags or containers with the sealant layer being disposed to the inner content side of the bag or container.

  • Patent number: 6576306
    Abstract: This invention relates generally to crystalline propylene polymers, to methods for their production and to methods for their use in film applications. Specifically, this invention relates to crystalline propylene polymers comprising both propylene homopolymer and propylene copolymer. The compositions are prepared using metallocene catalyst systems comprising at least two metallocenes in a polymerization process that involves the sequential or parallel polymerization of propylene homopolymer and copolymer using propylene with a small amount of comonomer, preferably ethylene. The polymerization is catalyzed by a dual metallocene catalyst system. The resulting polymers have a broad, bimodal molecular weight distribution. The resulting polymers are excellent for use in the production of biaxially oriented films or non-oriented films.

    Abstract: The present invention relates to an airbag cushion which exhibits a low amount of seam usage (in order to attach at least two fabric panels or portions of a panel together) in correlation to an overall high amount of available inflation airspace within the cushion itself. These correlated elements are now combined for the first time in what is defined as an effective seam usage index (being the quotient of the length of overall seams on the cushions and the available inflation airspace volume). The inventive cushion must have at least one substantially straight seam and must possess an effective seam usage factor of less than about 0.11. A cushion exhibiting such a low seam usage factor and also comprising an integrated looped pocket for the disposition of an inflator can is also provided as well as an overall vehicle restraint system comprising the inventive airbag cushion.
