Packaging container, packaged food and packaged feed, with the packaging container being produced by: preparing a hole-sealing sheet by providing, on a back surface of a base material whose bending strength (S) represented by the following formula (A) is no less than 0.20 m 3 /N, a pressure sensitive adhesive layer whose vertical peeling strength at 40° C., with respect to a surface of the gas-impermeable container, is in the range of 0.3-2 N/cm; and sealing a vent hole in the gas-impermeable container by the hole-sealing sheet. Packaged food and feed are obtained by enclosing food and feed in the packaging container. S=L/W ( m 3 /N )  ( A ) W: Weight per 1 m 2 of the sheet base material (N/m 2 ).
