MULTILAYERED CONTAINER EXCELLENT IN OXYGEN-BARRIER PROPERTY |
摘要 |
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. |
