Summary:PURPOSE:To surely prevent the penetration of water to the bonded part of heat sealing material from occurring, suppress the water absorption properties of base resin and consequently remarkably increase the water resistance of the bonded part of the heat sealing material by a method wherein fatty amide under concentrated state is present in both the mouth part of a contact packaging container and the surface of heat sealing material layer. CONSTITUTION:Fatty amide 4 under concentrated state is present on fatty amide 4-containing heat sealing material layer 2, which is provided on one side of metal foil (aluminum foil) and is to be heat bonded to the mouth part of a contact packaging container 10. In this case, the ratio of fatty amide absorbance to heat sealing material base resin absorbance measured at surface by Fourier transform infrared spectrometry is set to be 0.1 - 2 in order to obtain the desired heat sealing lid material of contact packaging container.
