  • 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.

  • Publication number: 20180079880
    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 linear low density polyethylene having a density less than 0.930 g/cm3 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 high density polyethylene having a density from 0.930 to 0.970 g/cm3and a peak melting point in the range of 120° C. to 135° C.; and (b) a coating on an outer surface of the second layer of the film comprising polyurethane. In another aspect, the coated film comprises a monolayer comprising from 70 to 100 percent by weight of a polyethylene having a density less than 0.
