Abstract
A packing sheet for discharging gas according to an exemplary embodiment of the present invention 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 includes: a lamination portion which is formed by partially laminating the first layer and the second layer; and a gap portion which is a region other than a region of the lamination portion and has a space formed between the first layer and the second layer so that the gas flows in the space. According to the packing sheet for discharging gas, a space, in which gas may flow, is formed by partially laminating the first layer having fine bores and the second layer made of a gas-permeable waterproof material, and as a result, it is possible to prevent a liquid leakage while smoothly discharging the gas created in the container.
