ABSTRACT:
A non-fluorocarbon oil and grease barrier packaging for storing materials, particularly products that need oil and grease resistant characteristics. The barrier packaging does not contain fluorocarbons, which improves the environmental rating of the oil and grease barrier packaging. The packaging is made by applying an acrylate based overprint varnish to a substrate and then curing the overprint varnish with a curable energy source, which regulates a cross-link density of the overprint varnish. Application can be flexography, rotogravure, or either rod or blade coated. The overprint varnish possesses oil and grease resistant characteristics, which allows packaging producers to forego use of oil and grease resistant coated substrates in their packaging manufacturing processes.
