Abstract
A packaging materialincludes a heat resistant resin stretched film layeras an outer layer, a thermoplastic resin layeras an inner layer, a metal foil layerarranged between these layers, and a colored ink layerarranged between the metal foil layerand the heat resistant resin stretched film layer. 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 layerand the colored ink layerare integrally laminated via an easily adhesive layer. 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.
