  • Publication number: 20200269552
    Abstract: A composite film includes a) a self-supporting layer of a polymer film (such as a polyester), b) an optional primer layer on the polymer film layer, wherein the primer layer includes a PVdX (X being halo), acrylic or vinyl resin; and c) a layer of heat seal composition on the primer layer, wherein the heat seal composition includes a polyolefin plastomer (POP) resin and a tackifier that constitutes at least 20 wt % of the heat seal composition. The composite film may be formed by applying a coating composition including the heat seal composition in a solvent to a primer layer on the polymer film or directly on the polymer film in absence of the optional primer layer, and then evaporating the solvent. The composite film may be heat-sealed to a surface of a container or a self-supporting film.

  • Publication number: 20190153180
    Abstract: Disclosed herein is a method of producing a composite film that includes a biaxially oriented polyethylene terephthalate film substrate layer and a crosslinked layer on a surface thereof, wherein the crosslinked layer comprises a reaction product of a functionalized ethylene vinyl acetate copolymer comprising multiple COOH groups per molecule, wherein the functionalized ethylene vinyl acetate copolymer comprises 10-50 weight % of vinyl acetate monomer units and an organic crosslinker comprising multiple reactive groups per molecule, wherein the organic crosslinker is a melamine, said reactive groups being reactive with the COOH groups. The method also includes applying a solution comprising the functionalized ethylene vinyl acetate copolymer and the organic crosslinker in an organic solvent or mixture thereof to the biaxially oriented polyethylene terephthalate film substrate, followed by drying to form the crosslinked layer.

  • Publication number: 20180332886
    Abstract: Disclosed is a smoking article containing a rod containing a smokable composition, an optional wrapper for the rod, and at least one polymer or oligomer comprising monomer units of a polycarboxylic acid ester disposed on or in the rod, the wrapper, or both. The polycarboxylic acid ester contains an acid moiety having at least two carboxylic groups, and at least two alcohol moieties independently selected from those corresponding to a cycloalkyl alcohol or an aryl alcohol. The cycloalkyl alcohol or aryl alcohol is a flavorant, or chemesthetic agent, or both. In addition, a method for the controlled release of these flavorant or chemesthetic agents is described, which comprises pyrolyzing at least one polymer or oligomer.

  • Publication number: 20170218152
    Abstract: A composite film includes a polyester film substrate layer and a crosslinked layer on a surface thereof, wherein the crosslinked layer includes a reaction product of a) a functionalized ethylene vinyl acetate copolymer including multiple COOH groups or multiple alcoholic OH groups per molecule; and b) an organic crosslinker including multiple reactive groups per molecule, the reactive groups being reactive with the COOH or alcoholic OH groups; wherein the adhesion strength between the substrate layer and the crosslinked layer is at least 177 g/cm (450 g/inch). A method of joining the composite film, optionally further including a heat-sealable polymer layer on the crosslinked layer, to a container or a self-supporting film, includes contacting the crosslinked layer or the heat-sealable polymer layer with the container or the self-supporting film or under heat sealing conditions.

  • Patent number: 9687023
    Abstract: A moist smokeless tobacco product for oral use comprises a pre-portioned piece of tobacco material semi-dissolvable, a super-hydrated membrane coating comprising a soluble, non-cross-linked component and an insoluble, cross-linked component, and a texture component. The tobacco material comprises moist smokeless tobacco. The texture component reduces the slipperiness and/or increases the friction of the moist smokeless tobacco product when placed in a user's mouth.
