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.
