  • Patent number: 8071191
    Abstract: The specification discloses a method for affixing a strip to an underlying web substrate. According to the method, a substrate web having at least one surface is provided and at least one strip is applied over at least a portion of the substrate surface such that at least a significant portion of an underside surface of the strip disposed adjacent the substrate surface is unbounded to the substrate. A polymer coating is extruded over both the substrate surface and the strip. The strip is thereby affixed to the substrate surface by the coating while the portion of the underside surface of the strip remains substantially unbounded to the substrate surface. At the same time, a substantial portion of an upper surface of the strip adjacent the polymer coating layer is bonded to the coating layer. Also disclosed are packaging materials formed from the reinforced substrate.

  • Publication number: 20090183469
    Abstract: The wrapper for a ream of paper has an inner surface coated with polyethylene. When the wrapper is formed about a ream of paper, the inner layer overlaps and contacts the outer layer along a longitudinal seam. The polyethylene layer is used to create a seal with the application of heat. Areas of the inner surface in proximity to a heat source during the heat sealing process and where a seal will not be beneficial are covered with a heat shield, such as a varnish. In this way, damage to the paper is avoided. The varnish includes Styrenated Acrylic polymer, with Kaolin Clay and ink. The varnish is applied to the wrapper during the same manufacturing process as the polyethylene coating.

  • Patent number: 7279198
    Abstract: The specification discloses a method for extrusion coating a lightweight web. According to the method, a length of a lightweight web along with a length of a carrier web is fed to an extruder with the lightweight web positioned atop the carrier web. A polymer film is then extruded onto the combined lightweight web and carrier web to provide an extrusion-coated lightweight web. Thereafter, the extrusion-coated lightweight is separated from the carrier web. Also disclosed are extrusion-coated lightweight webs formed according to the method.

  • Patent number: 6656401
    Abstract: The specification discloses a method for extrusion coating multiple substrate webs on a dual or tandem extruder system having multiple extruder stations. The method includes as an initial step providing a first substrate web and a second substrate web wherein each of the first and second substrate webs has a coating side and an underside. The webs are temporarily joined to form a composite web wherein the respective coating sides face outward and the respective undersides face one another. A first polymer coating is extruded on the coating side of the first web at a first extrusion station. Subsequently, a second polymer coating is extruded on the coating side of the second web at a second extrusion station. The extrusion coated first and second webs are then separated. The invention enables more efficient and economical use of dual or tandem extruder systems.

  • Patent number: 5691022
    Abstract: A release liner based stock for use as a carrier web including a paper substrate having an upper surface and a lower surface. A release agent is coating on the top of the upper surface. The unique soap-based acrylic layer discourages curling of the base stock release liner, fiber pick-off contamination from the uncoated side of the paper substrate, and maintains a consistent peel off force required for removing a label from the release liner and deploying it on a target object.

  • Patent number: 4675016
    Abstract: A method for applying one or more curved composite elastic strips to a gatherable base material to elasticize portions of the base material comprises elongating a first strip of elastic material and joining a second strip of less elongated material to the elongated first strip in a longitudinally extending and laterally off-set relationship thereto to form a tensioned composite strip of elastic material. The second strip of material is sufficiently flexible in the plane of the composite strip and is sufficiently resistant to compression so that, upon release of the tensioning forces, the composite strip will curve laterally, i.e., in its own plane. The tensioned composite strip is adhered to the base material and in one mode of operation the tensioned forces are released only after adhering the composite strip to the base material. In such case, the base material is displaced somewhat by curving of the tensioned composite strip and may be pleated or otherwise rendered more readily displaceable.
