Abstract

PURPOSE:To prevent the tast and flavor of inner fillings from changing and retain a good fragrance retaining property by forming an inner surface layer in contact with fillings of a resin layer composed of linear saturated polyester resin having glass transition temperature of 40 deg.C or more. CONSTITUTION:A laminated resin sheet 6 is laminated on a packaging base 4 consisting of a biaxially oriented polyethylene terephthalate film 2 and an Al foil 3 through a bonding agent layer 5 constituted isocyanate bonding agent to form a desired packaging laminated material. At that time, the laminated resin sheet 6 is formed by co-extrusion molding a first resin layer 7 composed of linear saturated polyester resin having glass transition temperature of 40 deg.C or higher, a second resin layer 8 composed of linear saturated polyester of 10000kg/cm<2> tensional modulus and a third resin layer 9 composed of same resin as used for the first resin layer 7 with the second resin layer 8 as a core layer. Thus, the taste and flavor of fillings can be prevented effectively from changing by forming the laminated resin sheet 6.
