Abstract
This easily peelable absorption film is provided with an absorption film that contains a thermoplastic resin and an absorbing agent, and an easy-peel layer that is layered directly on one surface of the absorption film, wherein: the absorbing agent content is 20 mass % or more with reference to the mass of the entire absorption film; and when the easy-peel layer of the easily peelable absorption film is heat-sealed to another resin and the easily peelable absorption film is peeled from the other resin, the easy-peel layer agglomerates and peels away.
