Abstract
Abstract A packet for absorbing and immobilizing a liquid including an envelope which is degradable in the liquid and a liquid absorbing and immobilizing material in the envelope. One or more of a biocide, fungicide, antimicrobial, bacteriostat, sanitizer, disinfectant, scent or deodorizer is added to the liquid absorbing and immobilizing material for treating the liquid which is absorbed. The envelope has a dot matrix coating of heat-fusible material on degradable starch paper. The dot matrix coating permits heat-sealing of the envelope leaving the uncoated portions of the starch paper to degrade in solutions in which the dot matrix coating is insoluble.
