More Information
Summary:This invention relates to substrates for paperboard packaging, having a press applied barrier coating, which comprises : a first layer of particulate minerals (4); a first layer of a sizing material (6) including a copolymer binder for substantially preventing edgewicking located interior to said first layer of particulate minerals (4); a paperboard layer (8) located interior to said first layer of said sizing material (6); a second layer of said sizing material (10) located interior to said paperboard layer (8) ; and a second layer of particulate minerals (12) located interior to said second layer of said sizing material (10). Such structures of this type, generally, reduce the edgewick in the paperboard package such that catastrophic failure of the paperboard package is substantially reduced. This invention also relates to a method for producing such substrates.
