The present invention provides for a plastic sheet, especially one used in the construction of a plastic trash bag, which provides improved tear propagation properties. The plastic sheet has a plurality of protuberances in the plastic sheet, the protuberances defining a first set of substantially parallel curvilinear lines in a first direction, and optionally, a second set of curvilinear lines in a second direction. The plurality of protuberances can be either indentations or protrusions in the plastic sheet, preferably formed through an embossing process. Preferably, the protuberances are circular in shape, but not necessarily uniform, and alternate between indentations and protrusions along the first, and possibly the second, curvilinear lines with the curvilinear lines preferably being wave-shaped.
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.
Apparatus And Method For Resisting Tear Propagation In Polymeric Products
A plastic bag for holding materials comprising at least one polymeric panel defining the outer walls of the plastic bag. The at least one polymeric panel is interconnected to form a substantially cylindrical shape. The at least one polymeric panel defines a machine direction and a cross direction perpendicular to the machine direction. A plurality of substantially parallel rows on the at least one polymeric panel wherein the plurality of substantially parallel rows is comprised of a plurality of curvilinear areas. The plurality of curvilinear areas having a protrusion or an indentation in the at least one polymeric panel. The bag further comprises a plurality of substantially parallel neutral areas wherein each substantially parallel neutral area is defined by an area between two adjacent rows in the plurality of substantially parallel rows.

Abstract:
The present invention provides an offset folded polymeric bag. The offset folding polymeric bag defines a plurality of layers, wherein the plurality of layers is divided into two sets of layers and a primary opening is defined between the two sets of layers. The first set of layers has a different width than the second set of layers to inform the consumer as to particular order for unfolding the bag with the least amount of difficulty, thereby preventing consumer frustration with thin film plastic bags.

Abstract:
The present invention is directed to an embossed drawtape embossed with an enhanced gripping pattern. The enhanced gripping pattern features one or more embosses which enhance the ability of a person to grip the drawtape of a drawstring trash bag when gripping the drawtape in the direction of the width of the drawtape.
The present invention is directed toward an improved elastic drawstring for use with a trash bag. The elastic drawstring is comprised primarily of a two-component polyethylene blend. The first polyethylene component is a linear low-density polyethylene (LLDPE) having a density of 0.915 g/cc or less, with a preferred range of between 0.900 g/cc and 0.915 g/cc. In certain preferred embodiments, the density of the first polyethylene component is approximately 0.906 g/cc. The second polyethylene component is a low-density polyethylene (LDPE) having a density of between 0.915 g/cc and 0.929 g/cc. In a preferred embodiment, the second polyethylene component has a density of approximately 0.918 g/cc.
