Abstract

A microwavable food packaging can be configured to absorb fluid. The packaging can include a first sheet and a flexible second sheet. The first sheet can include a first polymeric layer. The first sheet can define an upper portion of a food pocket. The flexible second sheet can include an absorbent layer. The absorbent layer can include a paper-based side and a polymer-based side. The paper-based side can include paper fibers, define a bottom of the food pocket and be configured to absorb fluid released from food disposed within the food pocket. The first polymeric layer can be bonded to the polymer-based side through the paper-based side to form a non-hermetic seal, the non-hermetic seal enabling passage of moisture therethrough.
