ABSTRACT:
A packaging material capable of having a desired sealing strength with ease and a packaging bag using such material are provided. A packaging material, which serves as either one of a first and a second packaging materials to be heat-sealed to each other, includes a sealing portion. This sealing portion is relatively weaker in sealing strength and composed of an applied area of a coating agent preventing the heat sealing and a non-applied area of the coating agent. The applied area and the non-applied area are changed in an area size from each other depending on the sealing strength required for the sealing portion.
