Abstract
The invention is a resealable package comprising a liquid and gas impermeable container with a resealable opening and a stack of wetted fibrous absorbent materials and particularly wet fibrous sheet material having interposed between the sheets of wetted absorbent materials at pre-determined intervals a liquid barrier layer. The liquid barrier layer is generally a thin flexible polymeric material which is impervious to the liquid used to wet the absorbent sheet material and is not reactable with the liquid or the absorbent sheet material.
