  • Acid-functional copolymer coatings for polymeric substrates
    Patent number: 11802188
    Abstract: Embodiments of the present disclosure provide a coated film structure including a substrate layer, an overcoat layer, and at least one intermediate layer disposed between the substrate layer and the overcoat layer. The substrate layer includes a polymer film substrate, the overcoat layer includes an acid-functional copolymer, and the at least one intermediate layer includes aluminum oxide. The coated film structure has an oxygen transmission rate of less than about 3.00 cm3/m2/day at 50% relative humidity and 23° C. as measured in accordance with ASTM D3985. Further, the coated film structure has a water vapor transmission rate of less than 2.50 g/m2/day at 90% relative humidity and 37.8° C. as measured in accordance with ASTM E-398.
    Type: Grant
    Filed: June 12, 2019
    Date of Patent: October 31, 2023
    Assignee: Michelman, Inc.

  • Coated film structures with an aluminum oxide intermediate layer
    Patent number: 10766228
    Abstract: Embodiments of the present disclosure provide a coated film structure including a substrate layer, an overcoat layer, and at least one intermediate layer disposed between the substrate layer and the overcoat layer. The substrate layer includes a polymer film substrate, the overcoat layer includes polyvinyl alcohol, and the at least one intermediate layer includes aluminum oxide. The substrate layer has a thickness from 1 ?m to 120 ?m and the overcoat layer has a dry coat weight of from about 0.05 g/m2 to about 1.5 g/m2. The coated film structure has an oxygen transmission rate of less than about 0.70 cm3/m2/day at 90% relative humidity and 23° C. as measured in accordance with ASTM D3985. Further, the coated film structure has a water vapor transmission rate of less than 1.00 g/m2/day at 90% relative humidity and 37.8° C. as measured in accordance with ASTM E-398.
