The flexible gastight material for the landfill site provided in the present application has a micro-closed-cell foam structure. The closed-cell elastic structure of the flexible gastight material may block the volatilization of toxic and harmful odors, and may cut off the diffusion path of the odors by combining with gas treatment systems at the landfill site. The flexible gastight material has excellent water blocking and gas sealing performance.
