Abstract
The present invention relates to polymeric bags, particularly polymeric drawstring trash bags. The present invention comprises a trash bag having an elastic drawstring. The elastic drawstring trash bag features a short seal and an inner seal at each upper corner of the drawstring trash bag. The short seal and inner seal are separated by a small unsealed area. The inner seal serves to reduce the upper opening of the drawstring trash bag, while the elastic drawstring utilized with the bag provides a bag that allows the bag to fit snugly on many common trash receptacles.
