  • Publication number: 20100323140
    Abstract: A multilayered container with excellent heat resistance which is obtained by melt molding and has an interlayer made of an oxygen-absorbing barrier resin composition. The multilayered container comprises inner and outer layers comprising an olefin resin and, sandwiched between the inner and outer layers, an interlayer made of an oxygen-absorbing barrier resin composition. The multilayered container is one formed by melt molding. In thermal analysis of a container barrel part, it has a quantity of heat of isothermal crystallization after heating from 30° C. to 130° C. at 100° C./min of 0.5 J/g or larger. In the analysis, the barrel part, after cooling from 200° C. to 130° C. at 100° C./min, gives an isothermal crystallization profile in which the time period to a peak top is shorter than that in a multilayered container including an interlayer consisting only of the base resin (oxygen-barrier resin) constituting the oxygen-absorbing barrier resin composition.

  • Publication number: 20100133468
    Abstract: A high-quality oxygen-absorbing resin composition which is obtained without suffering resin scorching. Also provided are pellets for the oxygen-absorbing resin composition which comprise a thermoplastic resin (A) and an oxidation catalyst. After the pellets are mixed with a trigger resin and a thermoplastic resin (C), the trigger resin functions as a trigger to cause the oxidation of the thermoplastic resins (A) and (C) to proceed. As a result, the resultant composition absorbs oxygen.

  • Publication number: 20050142373
    Abstract: The object of the present invention is to provide an oxygen-absorbing resin composition having a high oxygen absorbability and capable of absorbing oxygen for a long period of time. The present invention provides an oxygen-absorbing resin composition comprising polyolefin resin (A) obtained by polymerizing an olefin having 2 to 8 carbon atoms, resin (B) which is other than resin (A) and which acts as a trigger for the oxidation of resin (A), and transition metal catalyst (C), wherein resin (B) is dispersed in the matrix of resin (A) so that the oxidation reaction of matrix resin (A) is caused and thus oxygen is absorbed when the oxygen-absorbing resin composition is brought into contact with oxygen. This oxygen absorbing resin composition has a high oxygen absorbability and is advantageous in cost because oxygen is absorbed in resin (A).
