A continuous chain of connected absorbent pouches comprises a first panel, a second panel, and a super-absorbent material. Each of the absorbent pouches is adapted to absorb liquids. The first panel and the second panel are attached to each other along their respective general peripheries so as to form a space therebetween. The space comprises super-absorbent material. At least one of the first and second panels has at least one hole formed therein. The hole is of sufficient size to be permeable to liquid. Each of the pouches is adapted to absorb at least about 20 times its own weight of a 0.9 wt. % saline solution in an unloaded condition.

1. A process of using absorbent pouches to form pre-padded trays, comprising:providing a continuous chain of connected absorbent pouches, each of said absorbent pouches adapted to absorb liquids, each of said pouches comprising a first panel, a second panel, and a super-absorbent material, said first panel and said second panel being attached to each other along their respective general peripheries so as to form a space therebetween, said space consisting essentially of said super-absorbent material and in the absence of tissue paper, fibrous material and gel strips, at least one of said first and second panels having at least one hole formed therein, said at least one hole being of sufficient size to be permeable to liquid, and each of said pouches adapted to absorb at least about 20 times its own weight of a 0.9 wt. % saline solution in an unloaded condition;severing one of said connected absorbent pouches from said continuous chain of pouches at a selected length;providing trays; andattaching one of said severed absorbent pouches to a respective one of said trays via an attaching means so as to form the pre-padded tray. 2. The process of claim 1, wherein said selected lengths of said absorbent pouches are less than the lengths of said trays. 3. The process of claim 1, wherein said selected lengths of said absorbent pouches generally correspond to the lengths of trays. 4. The process of claim 1, wherein said continuous chain of connected absorbent pouches is wound in a roll. 5. The process of claim 1 further including adding a food product to the pre-padded tray. 6. The process of claim 1, wherein said super-absorbent material is adapted to absorb at least about 25 times its own weight of a 0.9 wt. % saline solution in an unloaded condition. 7. The process of claim 6, wherein said super-absorbent material is adapted to absorb at least about 30 times its own weight of a 0.9 wt. % saline solution in an unloaded condition. 8. The process of claim 1, wherein at least one of said panels is made from a woven material, non-woven material, liquid-permeable film, perforated film, impermeable film, open-celled polymeric foam, and close-celled polymeric foam. 9. The process of claim 1, wherein each of said panels is independently made from a woven material, non-woven material, liquid-permeable film, perforated film, perforated close-celled polymeric foam, or open-celled polymeric foam. 10. The process of claim 1, wherein each of said first and second panels has a plurality of holes formed therein, said plurality of holes being of sufficient size to be permeable to liquid and of a sufficient size to inhibit said super-absorbent material from leaving said space. 11. The process of claim 1, wherein said pouch consists of said first panel, said second panel, and said super-absorbent material. 12. A process of using at least one absorbent pouch to form at least one pre-padded tray, comprising:providing at least one absorbent pouch adapted to absorb liquids, said pouch comprising a first panel, a second panel, and a super-absorbent material, said first panel and said second panel being attached to each other along their respective general peripheries so as to form a space therebetween, said space comprising said super-absorbent material, and at least one of said first and second panels having at least one hole formed therein, said hole being of sufficient size to be permeable to liquid, at least one of said first and second panels comprising a polymeric foam, and said pouch adapted to absorb at least about 20 times its own weight of a 0.9 wt. % saline solution in an unloaded condition;providing at least one tray; andattaching one of said at least one absorbent pouch to a respective one of said tray via an attaching means so as to form the pre-padded tray. 13. The process of claim 12, wherein said at least one absorbent pouch is a chain of continuous connected absorbent pouches and further includes severing said chain of continuous connected absorbent pouches at a selected length. 14. The process of claim 12, wherein said super-absorbent material is adapted to absorb at least about 25 times its own weight of a 0.9 wt. % saline solution in an unloaded condition. 15. The process of claim 12, wherein at least one of said panels is made from an open-celled polymeric foam or a close-celled polymeric foam, said open-celled polymeric foam and said close-celled polymeric foam comprising an alkenyl aromatic polymer. 16. The process of claim 15, wherein said alkenyl aromatic polymer is polystyrene. 17. The process of claim 12, wherein at least one of said panels is made from an open-celled polymeric foam or a close-celled polymeric foam, said open-celled polymeric foam and said close-celled polymeric foam comprising at least one polyolefin. 18. The process of claim 12, wherein said super-absorbent material is a crosslinked polyacrylate. 19. The process of claim 12, wherein said at least one hole is a plurality of holes, the average diameter of said plurality of holes is less than about 0.1 mm. 20. The process of claim 12, wherein said pouch consists essentially of said first panel, said second panel, and said super-absorbent material. 21. The process of claim 12, wherein said space consists essentially of said super-absorbent material. 22. The process of claim 12, wherein said pouch consists of said first panel, said second panel, and said super-absorbent material. 23. The process of claim 12, wherein said first layer comprises a polymeric foam and the second layer comprises a non-woven material. 24. The process of claim 1, wherein each of said pouches comprises from about 1 to about 10 grams of said super-absorbent material. 25.
