  • Patent number: 8697215
    Abstract: The present invention relates to a preformed liner of tetrafluoroethylene/perfluoro(alkyl vinyl ether) copolymer adhered to the surface of a pipe, and in particular, an oil well pipe, without the need for either a primer layer or an adhesive. The liner comprises an effective amount of metal powder which provides adhesion between the liner and the surface of the pipe. The present invention also relates to a process for making such pipe, where in a preferred embodiment, the liner is co-extruded to form an inner layer and an outer layer. This co-extrusion embodiment is particularly useful in applications where high purity is necessary. In this case, the inner layer comprises an effective amount of metal powder and the outer layer is pure tetrafluoroethylene/perfluoro (alkyl vinyl ether) copolymer.

  • Patent number: 8642147
    Abstract: A process that is faster than conventional processes for manufacturing a film tube from a polymer and/or metal film material includes moving the film tube in relation to the joining tools during the joining process. Before the joining process of the film tube, the metal film material exists in the form of at least one film web. The edges of this film web are joined to one another in a joining process forming at least one longitudinal joint seam. During the joining process the film tube is moved in relation to the joining tools.

  • Patent number: 8642101
    Abstract: The object of the invention is a liquid packaging board (1), wherein the base board (3) is provided with at least one polymeric coating layer on both sides thereof to decrease the flavor scalping from a packaged liquid, such as citrus fruit juice. Inside the baseboard, there is a layer (6) of ethylene methyl acrylate copolymer either in a direct contact with the packaged liquid or coated with a thin layer of polyolefin. The invention also relates to a closed package for liquid food that is formed from the liquid packaging board (1) by folding and seaming, wherein the side that comes in contact with the food product, correspondingly, comprises an EMA layer and, possibly, a thin polyolefin layer on top of the same. The invention further comprises the use of EMA in decreasing the flavor scalping from the packaged liquid by the packaging material.

  • Publication number: 20130337209
    Abstract: A four-layer film for packaging, including blister packaging, is described. Layer 1 may be a rigid film, such as a polyvinyl chloride (PVC) or polyester. Layer 2 may be a moisture barrier, such as polychlorotrifluoroethylene (PCTFE). Layer 3 may be an oxygen barrier, such as a co-extruded film having a polyethylene (PE) layer, an EVOH layer, and a second PE layer. Layer 4 may be a relatively thin layer of a rigid film, such as a PVC or polyester. In this arrangement, Layer 2 may protect the contents of the package from external or atmospheric moisture. Layer 2 may also protect Layer 3 from atmospheric moisture, thereby helping to preserve the effectiveness of Layer 3 as an oxygen barrier.

  • Patent number: 8580369
    Abstract: Embodiments of the invention relate to a cover, a method of covering, and a cover system to be used with shipments of products transported by air with ULDs. The cover system provides thermal protection to temperature-sensitive products in or on the ULD. The cover system maintains the proper relative humidity level and gas concentrations (oxygen, carbon dioxide and ethylene) for horticultural product loads. The cover system can also have antimicrobial properties. In addition, the cover system decreases the amount of water vapor released in the cargo holds which is known to affect the reliability of the aircraft smoke detection system and to cause false fire alarms.

  • Patent number: 8541078
    Abstract: Fuel cartridges for fuel cells are disclosed. One fuel cartridge has an outer casing, an inner liner containing fuel, and a valve component adapted to transport fuel from the fuel supply to a fuel cell. The outer casing and the inner liner are made by blow molding and as the fuel is transported from the fuel supply, the inner liner pulls away from the outer casing. Another fuel cartridge includes an outer casing, an inner liner containing fuel, and a valve component adapted to transport fuel from the fuel supply to a fuel cell. The inner liner is integral to the outer casing at a region proximate to the location of the valve component.

  • Patent number: 8535772
    Abstract: A transparent article includes a continuous polyester matrix having at least one incompatible filler dispersed therein. The incompatible filler provides domains in the polyester matrix, each domain having a particular dimension, thus providing a range of dimensions for the domains in the article. To create haze, the dimensions are within the range of from about 380 nm to about 720 nm. Once the range of dimensions is determined, a light absorbent composition can be found which absorbs light at a range of wavelengths that at least substantially covers the range of dimensions of the domains. In doing so, it has been found that the haze of the article can be substantially masked. Method for producing the article and for masking the haze are also provided.
