Abstract: A sustainable paper composite food packaging material includes an absorbent layer and a non-absorbent layer, the absorbent layer in one embodiment having an oleophilic surface and the non-absorbent layer having an oleophobic surface. The absorbent layer is physiologically safe for food contact applications, such as removing oil and grease from pizza and other cooked foods. Food packaging assemblies containing the sustainable paper composite material, for example, a pizza box assembly, and methods of using the composite material to blot oil and other liquids from food surfaces are also described herein. In one embodiment, the composite material is positioned beneath the pizza with the absorbent layer facing upwardly to contact the underside of the pizza in use.

Abstract: Composite materials of this invention include an absorbent layer and a non-absorbent layer, the absorbent layer having a textured surface for absorbing and trapping liquids, for example, oil, grease, or water, and the non-absorbent layer having an oleophobic surface that acts as an oil and grease specific liquid barrier. In one example, the surface texture includes a system of ridges and valleys that enhance the composite materials' ability to absorb and hold liquids. The material further includes one or more lamination layers. The lamination layer acts as a general liquid barrier between the absorbent layer and non-absorbent layer. This additional liquid barrier enhances the liquid repelling effect of the non-absorbent layer to more effectively trap liquids in the absorbent layer, thereby preventing liquids from seeping through the material onto an external surface.
