PROBLEM TO BE SOLVED: To provide a ventilation label which has a simple structure, but which can maintain a good sealed state inside a package body which is hermetically closed by the package body, and which allows gas to be released from the inside of the package body to the external environment to eliminate the atmospheric pressure difference between the inside of the package body and the external environment as needed.SOLUTION: A ventilation label, which includes a deformable body layer and a frame-like adhesive layer laminated on the lower surface side of the body layer, can be attached to a package body. The adhesive layer includes: a peeling adhesive area that has the properties of being peeled from and being re-attached to the package body; and an attaching area that has higher peeling strength from the package body than the peeling adhesive area. In the ventilation label, the peeling adhesive area is formed from the inner peripheral edge to the outer peripheral edge of the frame-like adhesive layer. |
