PROBLEM TO BE SOLVED: To provide a package for enclosing a photographic developer capable of industrially easy mass production and using an alkali-proof resin film not containing chlorine in the molecular structure. SOLUTION: A laminated sheet based on a laminated body obtained by successively laminating a pulp sheet 11, a 1st adhesive layer 12, metallic foil 13, a 2nd adhesive layer 14 and an alkali-proof resin film 15 comprising one or more alkali-proof resin layers not containing chlorine in the molecular structure is folded with the alkali-proof resin film 15 inward and each side is sealed 16 to obtain the objective package for enclosing a photographic developer. The alkali-proof resin layer of the alkali-proof resin film 15 brought into contact with the photographic developer is based on a thermoplastic resin having 80-180 deg.C melting point.
