IMPROVED PVOH BARRIER PERFORMANCE ON SUBSTRATES |
摘要 |
<p>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/m2, based upon area of th e 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.</p> |
