  • Patent number: 7132490
    Abstract: Provided is a lactic acid-based resin composition that comprises a lactic acid-based resin (component (A)), and an ethylene-unsaturated carboxylic acid copolymer (component (B)) and/or an ethylene-unsaturated carboxylic acid copolymer ionomer (component (C)). The lactic acid-based resin composition has good physical properties in melt and can be efficiently formed into films and laminates through casting or extrusion lamination. The paper laminates obtained through extrusion lamination with the resin composition have good moisture barrier property, and have the advantages of good antibacterial ability, good biodegradability and low combustion heat. And the moldings obtained from the resin composition of the invention have a characteristic which is excellent in impact strength. Further, the films and sheets formed of the resin composition have good low-temperature heat-sealability and hot-tack sealability, and the resin composition well serves as a sealant.

  • Publication number: 20060057318
    Abstract: The present invention relates to a multi-layer structure constructed of two or more layers including a potassium ionomer layer (X) having a low surface resistivity and a layer (Y) comprising a polymer material having a high surface resistivity like LLDPE as a surface layer, where the static charge decay characteristics of the layer (Y) is improved. This type of two layer or three layer structure having the layer (X) as its intermediate layer or another surface layer gives good slip characteristics, abrasion resistance, and dust-free characteristics, and hence is useful for packaging materials, such as films, sheets and containers.

  • Patent number: 6398059
    Abstract: The molded component is formed by mixing or laminating a barrier resin (A) having a solubility parameter (calculated from the Fedors' equation) of more than 11 and a thermoplastic resin (B) having a solubility parameter (calculated from the Fedors' equation) of not more than 11. The molded component has excellent gasoline barrier properties and also excellent performance in thermal fusion properties and mechanical strength. The fuel container provided with such a molded component is significantly improved with regard to leakage of fuel from the molded component portion.
