It all depends on how many films you intend to develop and over what period. I mix 5 litres and then pour into two 3L wine bags having drunk the wine, cleaned the bags and kept the cardboard boxes in which the bags are kept

Even if your use will be less than these numbers of films Xtol is relatively cheap and can be thrown away.
Worth thinking about in my opinion and maybe not as inconvenient as it first appears
