ABSTRACT:
A gussetted plastic bag and liner, wherein the bag is maintained open by an attached elastic band. The elastic is placed on either side of at least one gusset fold(s) in an untensioned state, so as to bridge the gusset. When the bag top is folded over a container rim, the elastic is stretched on the outside of the container. This placement permits the bag to be folded flat while providing a means to keep the bag open during use. The elastic is useful as a closure after use.
