The bag fabric includes an elastic layer and a surface layer adhered thereto. The elastic layer is preferably formed from foamed polybutylene gum or styrene or butadiene gum. The surface layer being preferably formed a fabric of nylon yarns or polyester yarns. The bag body has an elasticity that enables the opening to be stretched open to facilitate placement of articles into the bag body and to contract thereafter to ensure that the contents of the bag body do not fall out.
