20080253699 | 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. | 10-16-2008 |
20090003738 | APPARATUS AND METHOD FOR ENHANCED TEAR RESISTANCE PLASTIC SHEETS - 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. | 01-01-2009 |
20090104388 | APPARATUS AND METHOD FOR OFFSET FOLDED POLYMERIC BAGS - 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. | 04-23-2009 |
20090151304 | APPARATUS AND METHOD FOR IMPROVED PACKING OF POLYMERIC BAGS - The present invention provides an improved apparatus, method and system for packing and storing carry-out bags, especially bags known as T-shirt bags. In particular, the present invention comprises providing a packaging bag for securing a plurality of polymeric bags. The polymeric bags may be individually folded, or alternatively, folded as groups of polymeric bags. The polymeric bags are placed in the packaging bag and the air inside the packaging bag is removed. The outside, ambient pressure forces the packaging bag to compress onto the polymeric bags. The resulting packaging is generally dumbbell shaped because of the distribution of material in the polymeric bags which provides numerous advantages as discussed herein. | 06-18-2009 |
20110002559 | Embossed Drawtape for Polymeric Bags - 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. | 01-06-2011 |
20110052103 | Elastic Drawstring for Trash Bags - 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. | 03-03-2011 |
20110081103 | Drawstring Trash Bag - The present invention is directed toward a drawstring trash bag. The drawstring trash bag features an upper opening with a first and second hem extending along the upper opening of the bag. A first drawstring is disposed within the first hem while a second drawstring is disposed within the second hem of the bag. The first drawstring and the second drawstring have different elastic properties. Both drawstrings may be pulled through cut-outs that are centrally located on the respective first and second panels along the upper opening. The elastic drawstring preferably has an elastic recovery percentage that is at least 10 points greater than the elastic recovery percentage of the non-elastic drawstring. | 04-07-2011 |
20110311167 | Closure Device for Reclosable Bag - A reclosable bag comprising a first bag wall and a second bag wall joined along a first side, a second side, and a bottom of the reclosable bag. The reclosable bag having a top that is generally open to allow contents to be placed therein. The reclosable bag has a first closure which further comprises a first male closure element and a first female closure element. The first male closure element and the first female closure element are disposed in an opposing configuration on the first bag wall and the second bag wall. The first male closure element has a first hook portion and a second hook portion. | 12-22-2011 |
20120082405 | Drawstring Polymeric Bag - The present invention is directed to a drawstring trash bag having drawstring access holes with increased width and a method for producing drawstring trash bags having drawstring access holes with increased widths. | 04-05-2012 |
20150023616 | Elastic Drawstring for Trash Bags - 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.
