Beschreibung
Zusammenfassung:	Thin absorbent food pads with a bulk under 0.5 cm are provided having an insulation layer and from 3 to 30 sheets of compressed wet resilient cellulosic material wherein the absorbent pad has an absorbent capacity of at least 10 grams fluid per gram absorbent material and which expands in volume by at least 50%, relative to dry volume, upon wetting. The thin absorbent pads may be provided by calendering the insulation layer and cellulosic sheets under a force of about 100 to 1500 pounds per linear inch, thereby reducing the bulk of the pad by 30 to 60% and creating a pad which will significantly expand upon wetting to achieve an aqueous absorbent capacity of about 0.85 grams fluid per square centimeter (5.5 g/square inch).
