The present invention is a high capacity lobed plastic bag with additional length for securely storing trash, debris and/or other materials produced from a polymeric tube. The polymeric tube defines the outer wall of the plastic bag with an upper end and a lower end. The lower end of the polymeric tube is sealed to form the bottom of the plastic bag. The upper end of the polymeric tube defines the opening of the plastic bag and features a curvilinear configuration. The bag according to the present invention overcomes the length and capacity constraints of the prior art and has a length greater than 41 inches from the bottom of the bag to a lowest point defined by the curvilinear configuration at the opening of the plastic bag. Thus, the plastic bag with a length greater than 41 inches has an increased capacity.
