An object of the present invention is to provide a food paper container which can be packaged by heat sealing and which does not cause the adsorption of the taste of limonene or the like, and can be stored at room temperature for a long period of time.nIn the solution of the present invention, the paper substrate layer/paper adhesive layer/barrier first adhesive layer/barrier layer/barrier second adhesive layer/heat-sealable PET resin layer constitute a layer for a paper container. The material has a oxygen barrier of 2.0ml/m2. D. Below atm, the crystal portion of the heat-sealable PET resin layer is less than 15%, and the amorphous portion is 85% or more. |
