A bag formed from a single sheet of flexible material having two ends and two edges folded parallel to the ends to provide front and back surfaces that are sealed together along the edges to provide a pocket. Each of the surfaces extends toward an opening into the pocket through which articles for support may pass and from which articles may be removed. One of the surfaces extends beyond the opening of the pocket and is folded over the end of the other surface. The end of the folded over surface is positioned directly below the end of the other surface outside of the bag and elastic members are held captive within the ends whereby by stretching the bag in the direction of the sealed edges and maintaining the bag in a stretched condition a plurality of closure seals are formed to close the opening to the bag. In addition, when the bag is joined sealed edge to sealed edge and stretched around a form, the stretched ends of the bag that form the opening to the bag also support the bag around the form.

A bag comprising at least one sheet of a flexible material, having two ends and two ends, folded parallel to the ends to provide a front and back surface and sealed substantially along the edges to provide a pocket, each of said surfaces extending toward an opening into said pocket through which articles for support may pass and from which articles may be removed, one of said surfaces extending beyond said opening and folded over the end of said other surface so that the end of the folded over surface is positioned below the end of the other surface throughout substantially their entire lengths, and the folded over end is positioned outside of said bag, and elastic means under tension at each of the ends for drawing said sealed edges toward each other and when said bag is stretched in the direction of said sealed edges and maintained in a substantially stretched condition the elastic means of one end acts toward the plastic means of the other end throughout substantially the entire length of the ends and said elastic means of one end acts toward one surface of the bag and said elastic means of the other end acts toward both surfaces of the bag below the first mentioned end throughout substantially the entire length of the ends to provide a plurality of closure seals at said opening.
