  • Publication number: 20070078212
    Abstract: Disclosed herein is a nanocomposite composition having barrier properties. The nanocomposite composition is prepared by dry-blending a polyamide resin and a nanocomposite having barrier properties composed of polyamide and a layered clay. Since the nanocomposite composition has superior barrier properties and good moldability, it is suitable for use in the manufacture of closed containers, sheets having barrier properties, and films having barrier properties. Further disclosed is an article manufactured from the nanocomposite composition.

  • Publication number: 20060178466
    Abstract: A nanocomposite composition having a barrier property is provided. The compositon is prepared by dry-blending a styrene-based resin, a resin having a barrier property/intercalated clay nanocomposite, and a compatibilizer. The compositon has superior mechanical strength and moldability, and superior oxygen, organic solvent, and moisture barrier properties, and thus can be used to manufacture various articles having a barrier property.

  • Publication number: 20060121228
    Abstract: A tube container having a barrier property is provided. A single-layer or 3-layer tube container is manufactured by molding a dry-blended composition including a polyolefin resin and a nanocomposite of a resin having a barrier property and an intercalated clay, and a compatibilizer. The single-layer or 3-layer tube container can be simply manufactured and has a superior barrier property, thereby preventing the decomposition of contents, compared to a conventional 5-layer tube container.
