  • Patent number: 8048532
    Abstract: Disclosed herein is an improved, metallized polymer film and method for preparing the same. Such films comprise a) at least one treated polymeric skin layer comprising butylene, and b) a metal layer deposited onto at least one surface of this polymeric skin layer. The polymeric skin layer can comprise a propylene-butylene copolymer or an ethylene-propylene-butylene terpolymer, with this copolymer or terpolymer containing from about 4 wt % to about 12 wt % of butylene. The polymeric skin layer is preferably preconditioned by subjecting an outermost surface thereof to plasma treatment which facilitates the deposition thereon of a strongly adhering metal layer which is preferably aluminum. The resulting multi-layer films exhibit metal adhesion bond strength of at least about 100 grams/25 mm. These films will preferably also exhibit a Water Vapor Transmission Rate of from about 0.05 to about 0.2 g/m2/24 hour, and an Oxygen Transmission Rate of from about 5.0 to about 20 cm3/m2/24 hour.

  • Patent number: 7626066
    Abstract: An oligomerization process in which hydrocarbon feedstocks are contacted with a hydrotreating catalyst in the absence of hydrogen and in the liquid phase. The catalyst is a heterogeneous catalyst selected from supported reduced metals, metals oxides, metal sulfides and combinations thereof. Preferred catalysts include mixed nickel and molybdenum oxides or mixed cobalt and molybdenum oxides. The process also oligomerizes sulfur compounds so that sulfur containing feedstocks can be treated without deactivating the catalysts.

  • Patent number: 7432405
    Abstract: A process for the disproportionation of cumene is disclosed which comprises the step of contacting a feed containing cumene, under disproportionation conditions, with a catalyst comprising a molecular sieve, preferably TEA-mordenite. The contacting step disproportionates at least part of the cumene in the feed to provide a disproportionation effluent containing benzene and a mixture of diisopropylbenzene isomers. The effluent is then recovered and contains, prior to any separation step, less 1% of ortho-diisopropylbenzene by weight of the total diisopropylbenzene content of said effluent, less than 1 wt % of n-propylbenzene, less than 5 wt % of triisopropylbenzenes and less than 5 wt % of disproportionation products other than benzene and diisopropylbenzenes.

  • Patent number: 7294380
    Abstract: Clear and opaque polymeric film structures for providing clear and opaque labels that are removable, respectively. The film structure includes a core layer and first skin layer, wherein the first skin layer contains a polymeric matrix of a material that allows a label, which has been produced from the film structure and applied onto a container or product, to be removed from the container or product by the solution employed in a process for re-using the container. The first skin layer is co-extruded along with the remainder of the layers of the film structure, or the first skin layer is deposited on the film structure as an emulsion or extrusion coating. The first skin layer can be contacted with a water-based adhesive to affix the label onto a particular product or product container. Labels produced from the film structure exhibit a desirable combination of excellent initial adhesion strength, moisture resistance and delaminatability, as well as excellent removability.

  • Patent number: 7279061
    Abstract: Improved metallized films are produced by transferring a protective layer onto a metal layer from the side of the film remote from the metal layer. The transfer preferably takes place in the metallizer shortly after metallization and before the metal layer is exposed to the atmosphere which reduces the tendency of the metal to oxidize leading to a purer metal layer with enhanced barrier properties.

  • Patent number: 7108060
    Abstract: Method and apparatus for fracturing different levels of a completion interval in a well. A workstring lowers a fracturing string which, in turn, is comprised of a base pipe which is blank except for perforated sections spaced along its length. Screen may be provided over said sections to block the flow of sand into the base pipe. An alternate flow path (e.g. shunt tubes) extends along the base pipe and has one or more outlets spaced along its length. A slurry is flowed into the annulus surrounding the fracturing string. As liquid is lost from the slurry, sand from the slurry will form bridges at said perforated sections thereby isolating portions of the annulus. Slurry then flows through the shunts tube(s) and out into the isolated portions to fracture the different levels in the completion interval.

  • Patent number: 6994291
    Abstract: An end-board for supporting and handling a core-wound roll of material, such as a roll of polymer film. The end-board includes a support plate having a product face, an outer face, a core support aperture, and a core channel, the core support aperture adapted to support a core plug or a core therein. The product face includes a roll recess for receiving an end of the core-wound roll within the roll recess when the core plug or core is positioned in the core support aperture. A locking collar may be used to selectively engage the support plate in the support plate core channel to prevent the supported core or core plug from passing through the core channel. A pair of handles within the support plate may be used to facilitate end-board manipulation.
