Abstract
A sealable lidding film for discharging gas according to an exemplary embodiment of the present invention may seal an opening of a main body, has a structure in which a first layer and a second layer, which are configured such that gas flows between one surface and the other surface, are stacked, and may include lamination portions which are formed by partially laminating the first layer and the second layer; and gap portions which are regions other than regions of the lamination portions and have spaces formed between the first layer and the second layer so that the gas flows in the spaces. According to the sealable lidding film for discharging gas, the spaces, in which the gas may flow, are formed by partially laminating the first and second layers having the fine bores, and as a result, it is possible to prevent expansion and deformation of the sealable lidding film or the container by smoothly discharging the gas created in the container.
