An absorbent pad is provided which is useful in a receptacle for containing and displaying food products which tend to exude juices or liquids. The absorbent pad comprises a mat of liquid absorbent material, which comprises a layer of paper wadding and a layer of wood fluff, with the layers being mechanically interconnected. A plastic liquid impermeable sheet overlies one side of the mat, and a plastic perforated sheet overlies the other side. When the food product is positioned upon the upper sheet of the absorbent pad, any exuded liquids will flow around the pad and enter the mat by capillary action through the perforated openings of the bottom sheet, and the liquids will be held out of contact with the food product to thereby minimize contamination of the product and maintain its appearance and improve its shelf-life. The pad also has independent utility as a moisturizing device for use in closed food containers or packages.

1. An absorbent pad useful in a food package to separate and maintain the exuded liquids from the food product to thereby minimize contamination of the food product, or as a device for moisturizing a closed food container or package, and comprising a mat of liquid absorbent material comprising a layer of paper wadding and a layer of wood fluff, said layers of paper wadding and wood fluff being mechanically interconnected to maintain the relative positioning thereof and the integrity of the wood fluff, a first sheet of liquid impermeable plastic material overlying and covering one side of said mat of liquid absorbent material, and a second sheet of plastic material overlying and covering the other side of said mat of liquid absorbent material, the peripheral edges of said first and second sheets being sealed together to enclose said mat therebetween, and with said second sheet only having a plurality of openings spaced over substantially the full area thereof and which permit passage of a liquid into said mat so as to be retained thereby, and wherein a layer of paper wadding is positioned immediately adjacent said second sheet, whereby said paper wadding acts to prevent dust from said wood fluff from passing outwardly through said openings. 2. The absorbent pad as defined in claim 1 wherein said mat of liquid absorbent material further comprises a liquid absorbing synthesized starch. 3. The absorbent pad as defined in claim 1 or 2 wherein said mat of liquid absorbent material further comprises a bacteriostatic agent. 4. The absorbent pad as defined in claim 1 wherein said openings have a diameter of about 0.01 inches and a density of between about 15 and 100 per square inch. 5. The absorbent pad as defined in either claim 1 or 4 wherein said openings include peripheral portions which are inclined outwardly from said second sheet and toward said mat, to thereby further retard the reverse flow of liquids outwardly from the mat and through said openings. 6. The absorbent pad as defined in claim 1 wherein said first and second sheets each have a thickness of between about 0.00035 and 0.005 inches.
