PROBLEM TO BE SOLVED: To provide an oxygen absorptive packaging sheet, which prevents an oxygen absorbent from infiltrating into or mixing with a food by mistake and facilitates the packaging work of the food for the storage package of the food using the oxygen absorbent, and to offer a food package using the oxygen absorptive packaging sheet. SOLUTION: A back film (12) of flat plastic film is stuck on the bottom surface of a cap film (11) having a number of projections formed by plastic film vacuum molding to form a plastic bubble sheet having a number of sealed caps (2), in which the oxygen absorbents (3) are enclosed, respectively, to make the packaging sheet (1). The food (4), which is kept fresh effectively by eliminating oxygen from its surrounding, is enclosed in a sealed packaging container, and the oxygen absorptive packaging sheet (1) is used to compose a part or the whole of the packaging container, or may be enclosed in it.
