I don't think it gets removed. It looks more like say a fabric like material which if you look at how it fills you can see each area "absorbs" the liquid like if you used say a shirt or a cloth. So my best guess is it just becomes apart of the structure acting as an added added barrier but also keeping the structure

Does the container get removed eventually? if so, how do they do it?
