<p><P>PROBLEM TO BE SOLVED: To provide a laminate structure for a packaging and a packaging container which have content-unadsorbable properties, and, in addition, have oxygen gas absorbable properties and oxygen gas barrier properties. <P>SOLUTION: The laminate structure for the packaging has: a first resin layer which is based on a resin having≥1,000 kg/m<SP POS="POST">3</SP>density, 30-200°C glass transition temperature and the content-unadsorbable properties and is arranged on the inside surface to be contacted with the liquid contents; a second resin layer based on other resin having≥1,000 kg/m<SP POS="POST">3</SP>density, 30-200°C glass transition temperature and≤(3.0 cm<SP POS="POST">3</SP>×20μm)/(m<SP POS="POST">2</SP>day atom) oxygen gas transmission rate; and a surface protective layer composed of a prescribed resin. The second resin layer or a resin layer to be arranged on the inside surface side of the second resin layer contains an oxygen absorptive substance by≥5% and <50%. A metallic foil sheet or an oxygen gas barrier layer composed of a vapor-deposited metal film or a vapor-deposited transparent film can be employed instead of the second resin layer. <P>COPYRIGHT: (C)2013,JPO&INPIT</p> |
