  • Publication number: 20070053737
    Abstract: A dispenser (10) for use as applicator or evaporator of fluent products (20) in a multitude of applications is constituted as a series of thin layered sheets (30) that can be in credit card format, having one face (32) that is impermeable to the fluent product, and an opposite face (34) with a localized perforated area (40) through which the product can pass and that for many applications is covered by a material that absorbs the fluent product, for instance a woven or non-woven fabric. The thin layered sheet (30) encloses at least one volume of a fluent product contained in at least one generally flat reservoir (36) defined by fluid-tight heat-sealed layers (33-2, 34-1) joined by a frangible seal (60) that is rupturable by the application of pressure.

  • Publication number: 20060154003
    Abstract: A flexible printable multilayer structure for use as an advertising display, a banner, or as a cover for vehicles, building facades, structures, luggage or the like, is composed of substantially halogen-free materials and comprises: a substrate layer of paper, board, polymeric film or woven or non-woven fabric; a substantially impermeable intermediate layer of an ethylene copolymer at least on one face of the substrate layer; and an outer layer of a thermoplastic hydrophilic polymer on the intermediate layer(s). The outer layer of the thermoplastic hydrophilic polymer has a permeability corresponding to an MVTR (moisture vapor transmission rate) of 1,000-20,000 g/m2/day measured according to ASTM 96BW and a thickness t from 5 to 50 ?m. The intermediate layer has a thickness T from 50 to 500 ?m.

  • Publication number: 20050202743
    Abstract: A package and a packaging material have a fabric-like appearance and/or texture. The packaging material is a layered structure that comprises an underlayer selected from paper, card stock, polymer films, and the like, and an outer layer including one or more of a woven fabric, a non-woven fabric, and fibers. The underlayer and the outer layer are adjacent and adhere to each other. At least one surface internal or external to the packaging material is printed or treated, or is rendered opaque by pigmentation, or has a pattern or other marking that is visible from outside the package.

  • Publication number: 20050182197
    Abstract: The present invention relates to a retortable sealant composition comprising i) at least a copolymer of propylene and ?-olefins, and ii) at least a copolymer of ethylene and alkyl acrylate, wherein the alkyl acrylate is present in an amount ranging from about 1 to less than 9 weight percent, relative to the weight of the sealant composition. It also relates to a retortable multilayer film or a retortable packaging comprising a sealant layer comprising such a composition.

  • Publication number: 20050106344
    Abstract: Disclosed is a multilayer structure, which comprises or is produced from a foil laminated to thermoplastic compositions using ethylene/butyl acrylate copolymer compositions as a tie layer. The multilayer structures can be useful as packaging films and industrial films. Also disclosed is a lamination process for producing the structure. Further disclosed are packages comprising the structures.

  • Patent number: 6500556
    Abstract: The present invention relates to an adhesive useful as a tie layer between a metal foil and polyethylene film that is a blend of two ethylene acrylic or methacrylic acid copolymers, one having a high-acid and a high-melt index and the other having a lower acid content and a lower melt index.

  • Patent number: 6224973
    Abstract: A multi-layer sheet suitable as sealable or peelable sheet specially used for closing foodstuff containers or blisters. This multi-layer sheet comprises a tie-layer between a substrate layer and a seal or a peel-seal layer comprising a polyolefin with acid or anhydride, grafted or copolymerized. The tie-layer has a thickness equivalent to 1-7 g/m2. The seal layer comprises a polyolefin. The total thickness of the combination of tie-layer and seal layer is equivalent to 3-20 g/m. This multilayer sheet is prepared by extrusion or coextrusion coating.

  • Patent number: 5750611
    Abstract: Odors and flavors in thermoplastic films and shaped articles may be reduced or eliminated by the addition of an adsorption agent to the thermoplastic. Thermoplastics include ethylene/acid copolymers and corresponding ionomers, and ethylene/acid/acrylate terpolymers and corresponding ionomers. The adsorption agent is a crystalline siliceous molecular sieve, having a framework of tetrahedral oxide units, in which at least 90% of the tetrahedral oxide units are SiO tetrahedra, a pore diameter greater than 5.5 Angstroms and a sorption capacity for water of less than 10% by weight at C. and 4.6 torr.

  • Patent number: 4756450
    Abstract: The dispenser comprises a flexible sealing-tight vessel (1) disposed in a rigid chamber (3) containing a ratchet mechanism comprising ratchet teeth (6) secured to a tubular element (4) and pawls (11) on resilient arms (10) mounted on a disc (9) disposed above the flexible bag (1). Resilient elements (12) fastened to the disc (9) lower it in proportion as a drink is withdrawn from the flexible bag (1). The ratchet mechanism retains the disc (9) when the pressure in the bag (1) becomes higher than atmospheric pressure.

  • Patent number: 4635630
    Abstract: This apparatus incorporates an enclosure (1) designed to contain water in which are immersed two electrodes (9,10) connected to an alternating current source (S). A tube (13) terminating in a nozzle (14) connect the top of this enclosure (1) to a venturi (15) which is connected upstream to the atmosphere and downstream to an inhalation mask (17), so as to form an air/water vapor mixture at a controlled temperature.

  • Patent number: 4501145
    Abstract: This process consists in raising the temperature of a probe immersed in the fluid to a temperature threshold corresponding to an electric resistance (R.sub.1), in measuring at least a second temperature threshold corresponding to a second resistance (R.sub.2, R.sub.3), in measuring the time elapsed between these different thresholds and in calculating a parameter of the fluid linked to the thermal transfer between the probe and the fluid, i.e., the temperature, the velocity, the viscosity, the density, the specific heat or the thermal conductivity.
