Abstract: The present disclosure describes systems and methods for affixing one or more geomembrane sheets to a concrete slab. The systems and methods can include an affixing member that adheres to the one or more geomembrane sheets. The affixing member can further include gripping extensions that adhere to the concrete slab. The gripping extensions can include distal ends embedded into the concrete slab. The gripping extensions can be integral with the affixing member. The geomembrane sheets may be used in the construction of a building to prevent vapor transmission through a concrete foundation from the supporting substrate.

A gusseted top may also be provided in the flexible pouch with a seal extending across the flexible pouch securing the top end of the flexible pouch.

Abstract: 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.

Abstract: The present invention relates to an enhanced perimeter polymer sheet. The enhanced perimeter polymeric sheet is generally comprised of a polymeric film substrate and may have a first enhanced perimeter region proximate to a first edge of the polymeric film substrate. The first enhanced perimeter region may further comprise an area extending generally along at least a portion of said first edge of the polymeric film substrate. A primary region of the enhanced perimeter plastic sheet may be defined by the polymeric film substrate. The primary region may be located generally inward from the first enhanced perimeter region and the primary region may have a set of attributes. The first enhanced perimeter region will have a set of attributes. Moreover, at least one attribute of the set of attributes of the first enhanced perimeter region may differ from a corresponding attribute of the set of attributes of the primary region.

Abstract: The present invention is directed to a drawstring bag comprised from a first panel and a second panel. The first panel and the second panel are joined along a first side, a bottom, and a second side. The first panel and the second panel thereby define an upper opening of the bag. The drawstring bag may further comprise a first hem located along the upper opening of the bag in the first panel and a first drawstring may be disposed within the first hem. The first drawstring may be manufactured from a drawtape film subjected to a cold-stretch process.

Abstract: The present invention is directed toward an improved construction of an elastic drawstring trash bag. The elastic drawstring trash bag described herein is comprised of a plastic bag made from two panels. An elastic drawstring is provided within hems running along the top of the two panels. The upper opening of the elastic drawstring bag is reduced (when the bag is in a relaxed state) by decreasing the distance between the interior edges of the short seals used to weld the drawstrings and bag together. Like an ordinary non-elastic drawstring bag, the elastic drawstring is pulled through access cutouts centrally located along the upper edge of the bag. When the bag of the present invention is in a relaxed state, the reduced upper opening width of the elastic drawstring bag is therefore less than bag proper width, allowing a consumer to pull the elastic drawstring bag over the lip of a trash receptacle and allowing the elastic drawstrings to snugly fit around the trash can.

Abstract: The present invention relates to a product container for rolls of product, particularly coreless rolls of trash bags. It may comprise a top panel, a bottom panel, a flexible outer wrap and multiple rolls of product. The top panel and the bottom panel may cover each or both ends of the rolls of product while the flexible outer wrap is placed securely around the top panel, the bottom panel, and the rolls of product.

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.

Abstract: The present invention is directed to a thermoplastic bag comprised of a front panel and a back panel. The front panel and back panel are generally joined along a first side edge, a second side edge, and a bottom edge of the respective front panel and back panel. The front panel has a distal edge with the distal edge folded over the front panel to provide a hem and an overlap area immediately below the first hem. The overlap area comprises at least two layers of polymeric film which are sealed together.

Abstract: The present invention is directed to a thermoplastic bag comprised of a front panel and a back panel. The front panel and back panel are generally joined along a first side edge, a second side edge, and a bottom edge of the respective front panel and back panel. The front panel has a distal edge opposite the bottom edge with the distal edge folded over the front panel to provide a hem and a overlap area immediately below the first hem. The overlap area comprises at least two layers of polymeric film which are sealed together.

Abstract: 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.

Abstract: The present invention is directed to a polymeric bag having a reduced gauge portion extending generally across the width of the bag, wherein the reduced gauge portion allows that area of the polymeric bag to be stretched more easily. This invention is especially advantageous in the context of drawstring trash bags wherein the reduced gauge portion encompasses the hems.

Abstract: The present invention is directed to a polymeric bag having an elastic portion extending generally across the width of the bag, wherein the elastic portion has a lower modulus of elasticity than the remainder of the bag.
