Zusammenfassung:	PURPOSE:To obtain a packing laminated material preventing the deterioration of the taste and aroma of packed content for a long period of time and reduced in the lowering of heat-seal strength even when hot hydrogen peroxide sterilization treatment for aseptic packing is applied by providing a specific polyester resin layer to the innermost surface of a base material composed of paper. CONSTITUTION:In a laminated material wherein a polyester resin layer is provided to the innermost surface of a base material composed of paper, a polyester resin is prepared from a specific dicarboxylic acid component unit A and a specific dihydroxy compd. component unit B. The unit A consists of 80-95mol% of a constituent unit derived from aromatic dicarboxylic acid and 20-5mol% of a constituent unit derivated from aliphatic dicarboxylic acid. The unit B consists of 55-90mol% of a constituent unit derived from ethylene glycol and 45-10mol% of a constituent unit derived from at least one of compounds represented by formulae 1-3.
