ABSTRACT:
In general, the product of the present invention is a plastic liner bag which includes an elastic band, integral with the open top of the plastic bag. The edge of the elastic band which is attached to the plastic bag has a circumference in its relaxed state which is approximately equal to the circumference of the open top of the bag. As such, the elastic band does not interfere with the folding or rolling of the plastic liner bags of the present invention. That is, the bag will lie flat on a flat surface. The method of the present invention comprises the steps of forming a plastic bag out of plastic sheet material so as to have an open end and attaching one edge of an elastic band in its relaxed state to the plastic sheet material so as to be integral with the open end of the bag when it is formed.
