Abstract

A paperboard substrate that can be used to provide a food packaging particle is provided having a water vapor barrier layer comprising HDPE in combination with a nucleating agent which is extruded on to a paperboard substrate. The resulting substrate has sufficiently good water vapor barrier when properties that dry foods such as cereals do not require a bag or inner liner as a separate moisture barrier.
