Title:
IMPROVED PVOH BARRIER PERFORMANCE ON SUBSTRATES
Document Type and Number:
WIPO Patent Application WO2005023945
Kind Code:
B1
Abstract:
Disclosed are coated substrates and methods for producing coated substrates. At least one surface of the substrates is coated with a polyvinyl alcohol polymer to render the substrates resistant to oil and grease. The polyvinyl alcohol polymer is coated at levels of a least 7 g/m<2>, based upon area of the coated surface of the substrate. Alternatively, the coating concentration is at least 5 wt. % of the weight of the substrate. The coatings may be applied by curtain coating or means and comprise at least one layer of a polyvinyl alcohol solution.
