  • Publication number: 20190105884
    Abstract: The present invention provides coated films and packages formed from such films. In one aspect, a coated film comprises (a) a film comprising (i) a first layer comprising from 70 to 100 percent by weight of a polyethylene having a density 0.930 g/cm3 or less and a peak melting point of less than 126° C.; (ii) a second layer comprising from 60 to 100 percent by weight polyethylene having a density of 0.905 to 0.970 g/cm3 and a peak melting point in the range of 100° C. to 135° C.; and (iii) at least one inner layer between the first layer and the second layer comprising from 40 to 100 percent by weight of a polyethylene having a density from 0.930 to 0.970 g/cm3 and a peak melting point in the range of 120° C. to 135° C., wherein the polyethylene is a medium density polyethylene or a high density polyethylene; and (b) a coating on an outer surface of the second layer of the film comprising a crosslinked polyurethane, wherein the coating is substantially free of isocyanate groups.

  • Patent number: 9828531
    Abstract: Provided is an adhesive composition comprising a continuous aqueous medium and further comprising (i) particles of a polymer dispersed in said aqueous medium; and (ii) particles comprising fatty amide and one or more fatty acid, wherein 50 mole % or more of said fatty acid is in the carboxylate form, and wherein the weight ratio of said fatty amide to said fatty acid is from 0.12:1 to 2.3:1, wherein said particles comprising fatty amide and one or more fatty acid are dispersed in said aqueous medium. Also provided is a method of bonding substrates using such an adhesive composition and a bonded structure made by such a method.

  • Patent number: 9579617
    Abstract: A composition is provided comprising dispersed particles in an aqueous medium, wherein said dispersed particles comprise fatty amide and one or more fatty acid, wherein 50 mole % or more of said fatty acid in is the carboxylate form, and wherein the weight ratio of said fatty amide to said fatty acid is from 0.12:1 to 2.3:1. Also provided is method of making that composition, comprising the step of applying shear to a mixture that comprises said fatty amide, said fatty acid, and water, wherein said applying shear is performed at a temperature above 59° C., and wherein the amount of water in said mixture is 70% or less by weight based on the weight of said mixture.
