Patent number: 5928972Abstract: To improve adhesive power to the skin without impairing excellent gas permeability and water vapor permeability when a laminate film comprising a film, a fiber fabric and an adhesive layer is sealed by heating at the same time in order to prevent an invasion of liquid from a side of the adhesive bandage.In an adhesive bandage comprising a base sheet made by laminating a film on a thermoplastic fiber fabric and an adhesive layer set on a surface of the thermoplastic fiber fabric of the base sheet, the adhesive bandage is pattern-sealed. The heat seal is preferably performed under the condition that the film does not melt but the thermoplastic fiber fabric melts, and only the periphery of the adhesive bandage may be pattern-sealed.Type: GrantFiled: May 15, 1997Date of Patent: July 27, 1999Inventors: Yasushi Mashiko, Takeshi Yoshida, Toshikazu Saito

Patent number: 5863642Abstract: A water resistant and vapour phase corrosion inhibitor composite material for wrapping around metallic items for protection and to reduce corrosion during storage and transportation. The composite material comprises a high strength, tear resistant, flexible scrim, a low density layer impregnated with a solid form vapour phase corrosion inhibitor, and a barrier layer to reduce the transmission of water, water vapour, oxygen and other environmental gases through the composite material. The barrier layer also reduces the atmospheric loss of gaseous vapour phase corrosion inhibitor from around the wrapped item. Each layer is formed from a polyolefin material to create a multi-layered polyolefin composite material that is easily recyclable.Type: GrantFiled: July 26, 1996Date of Patent: January 26, 1999Assignee: Fabrene, Inc.Inventors: Eric Henderson, Lorence J. Reed, Kevin D. Jagielski

Patent number: 5855980Abstract: The invention relates to a fabric with a laminate structure comprising flexible materials such as skins, woven fabrics and/or paper, and at least one metal material. The fabric is manually deformable without high elastic or plastic recovery. According to the invention, the structure consists of a substantially planar metal core essentially comprising a non-ferrous metal, this core being less than 0,15 mm thick and having the firmness necessary to provide a flexible stiffness, the thickness and metallurgical treatment being adapted to the weight of the flexible materials, and a layer of flexible materials bonded to either side of the core. The fabric of the invention is for use in the clothing industry, furnishings, interior decoration and stage designing.Type: GrantFiled: May 15, 1996Date of Patent: January 5, 1999Inventors: Bruno Roualdes, Santina Coerezza

Patent number: 5834381Abstract: A non-halogenated, tri-laminate fabric for automotive security shades or covers, comprising a layer of reinforcing fabric scrim juxtapositioned between at least two layers of a thermoplastic olefin film comprised of a rubber modified polyolefin compound, said layers being thermally bonded together to form a fire retardant, nontoxic tri-laminate fabric. The rubber modified polyolefin is a rubber modified polypropylene or polyethylene homopolymer and copolymer. The rubber is natural or synthetic. The preferred thermoplastic olefin film has characteristic melt peaks at temperatures ranging between about 61.degree. C. and 100.degree. C. and between about 105.degree. C. and 168.degree. C., with melt peaks forming preferably at about 86.degree. C. and 142.degree. C. Acceptable thermal lamination of the layers occurs at temperatures ranging between about 120.degree. C. and 140.degree. C.Type: GrantFiled: October 9, 1997Date of Patent: November 10, 1998Assignee: Highland Industries, Inc.Inventors: Frank Roe, Alex Churchill, Tom Fabbrini

Patent number: 5712008Abstract: A method and material for shrink wrapping articles includes wrapping the article with a shrink wrapping material having a shrink/stretch film outer layer and an inner layer of a woven fabric. The shrink/stretch film responds to heat by shrinking around the article being wrapped, while the woven fabric, which does not shrink or shrinks very little, forms pockets which bunch and gather up as shrinking takes place, thereby forming a cushion between the film and the object being wrapped. The woven fabric acts as a reenforcement for the film, both before and after shrinking, thus protecting the article wrapped from a hurled object and other similar hazards, and also protecting the article from direct engagement from the shrink/stretch film, which is relatively abrasive.Type: GrantFiled: February 12, 1996Date of Patent: January 27, 1998Assignee: Transhield Technology Co., L.L.C.Inventor: Gregory L.
