发明名称 DEOXIDATIVE MULTILAYER SHEET AND CONTAINER
摘要 PROBLEM TO BE SOLVED: To obtain a sheet having good appearance without exposing rusting or the like even by storing for a long period or hot water treating, by sequentially laminating from an inside a heat sealing layer, a flowable thermoplastic resin layer made of a thermoplastic resin having a specified melt flow rate, an oxygen absorbing layer, a gas barrier layer and a support layer. SOLUTION: The deoxidative multilayer sheet is formed by sequentially laminating from an inside a heat sealing layer 1, a flowable thermoplastic resin layer 2 made of a thermoplastic resin having a melt flow rate set to 2 to 50 g/10 min measured according to JIS K 6758, an oxygen absorbing layer 3, a gas barrier layer 4 and a support layer 5. In a sealed container obtained by heat seating the deoxidative multilayer container obtained by laminating the layers 1 to 5 and a cover material, the layer 3 at an end face of the container is covered with a resin for forming the layer 2. According to this, even if the container is preserved for a long period and thermally sterilized, exposure of the layer 3 to the surface of the end of the container can be prevented, and appearance properties and safety hydienic quality can be improved.
