Abstract:
A high gloss, disposable pressed paperboard food container includes a glossy bilayer finish. The container is formed in a heated die set from a paperboard substrate provided with a first finish coating layer consisting essentially of a styrene-butadiene resin composition and a second, top coating finish layer consisting essentially of an acrylic resin composition applied to the first finish coating layer. The products of the invention typically exhibit a 60 gloss of greater than about 40 gloss units, as well as reduced moisture pickup and enhanced rigidity.
