PROBLEM TO BE SOLVED: To overcome a problem such that a conventional compression preservation bag is constituted of polyethylene resin or the like, whereas, with the polyethylene resin having extremely small coefficient of friction, if a plurality of compression preservation bags are stacked one on another with Futon or bedding or the like stored therein, the bags on upper stages are liable to slide down, and to provide compression preservation bags which are hard to slide down even if a plurality of them are stacked up. SOLUTION: The provision of a bag body of synthetic resin made and equipping at least part of the outer surface of one side of the bag body with a slip-stop element which has a greater coefficient of friction than that of the bag body keep the bag bodies free from sliding down upon their stacking. In the case where a slip-stop element is provided only at the end of the open/close section side of the bag body, if a plurality of the bag bodies are stacked and only one out of them is pulled out, it can easily be pulled out without the stack of bags being collapsed. Furthermore, if there is no need to pull out any, the provision of a slip-stop element over the whole of one surface of the bag body pulls the bags tightly closer to one another so that even a plurality of bag-bodies stacked are free from collapse.
