A packaging material 1 includes a heat resistant resin stretched film layer 2 as an outer layer, a thermoplastic resin layer 3 as an inner layer, a metal foil layer 4 arranged between these layers, and a colored ink layer 10 arranged between the metal foil layer 4 and the heat resistant resin stretched film layer 2. As the heat resistant resin stretched film, a heat resistant resin stretched film having a hot water shrinkage rate of 2% to 20% is used, and the heat resistant resin stretched film layer 2 and the colored ink layer 4 are integrally laminated via an easily adhesive layer 30. In this packaging material, at the time of forming and sealing, and even being used in a somewhat severe environment such as high-temperature and humid environment, the colored ink layer will not be detached from the heat resistant resin stretched film layer.
