Lots of containers are lined with kraft paper primarily for reasons of hygiene or to simply isolate the cargo from direct contact with the container walls. The liner will act as a kind of sponge, catching and absorbing any droplets of water and then re-evaporating the moisture into the air. If liner is used without Absorpoles it could contribute to a kind of pumping effect, drawing moisture out of the cargo. When used together with Absorpoles the liner will act as a buffer in extreme conditions, and will prevent any container rain from reaching the cargo. Much the same can be said for so-called dew cloths.
