Abstract
The present invention is an absorbent pad for use below a meat product or the like during storage and during cooking. The pad includes a blotter means adapted to absorb liquids released from the meat product during cooking. In order to prevent substantial absorption prior to cooking, the pad also includes a heat shrinkable film adjacent the top surface of the blotter means, which film is partially attached to the blotter so as to leave at least one area which is not attached to the blotter means. The film also includes at least one opening feature, i.e. a perforation or pre-weakened area, in the at least one area which is not attached to the blotter means. As a result, when the pad is subjected to heat during cooking, the film around the perforation to weakened point shrinks so as to open a hole through the film to thereby allow liquids released from the meat product to pass into the blotter. Various configurations of perforations and pre-weakened areas are described.
