ABSTRACT:
A packaging folder formed from a paperboard coated on both surfaces with a coating resistant to water and water vapor, the coating so fractured to be pervious to air but substantially impervious to water. A process by which the coating layers are fractured to give the desired air permeability and water resistance by passing the coated folder around small diameter rollers.
