ABSTRACT An easily-openable packaging container comprises a container body and a multilayer lid member heat-sealed at the flange portion of the container body, in which the multilayer lid member has an interlaminar strength smaller than the adhesion strength between said flange portion and the inner layer of the multilayer lid member so that the multilayer lid member can be delaminated at a portion corresponding to the heat-seal portion at the time of opening, and a means for circularly peeling the inner layer of the multilayer lid member from the outer edge of the heat-seal portion to the inner edge or inner vicinity of the heat-seal portion is provided. The easily-openable packaging container has both excellent sealing property and easy openability and can be opened with a stable opening force.
