Abstract

PURPOSE:To further improve the shelf stability, freshness, taste etc. of contents by providing a water- and moisture-absorbing layer between two sheet substrates, at least either of which is permeable to water, thereby preparing a water- and moisture-absorbing sheet. CONSTITUTION:A water- and moisture-absorbing layer 3 is formed between two sheet substrates 1 and 2, at least either of which is permeable to water, thereby preparing a water- and moisture-absorbing sheet. It is preferable that the formation of the water- and moisture-absorbing layer 3 be so performed that the layer 3 is divided and scattered between these sheet substrates 1 and 2 to form a pattern, and the sheet substrates 1 and 2 be heat-bonded with each other in the areas where the water- and moisture-absorbing layer 3 is not present. As a water-absorbing agent to be used for the formation of the water- and moisture-absorbing layer, there may be employed a highly water-absorbing resin such as a product obtained by saponifying a copolymer of a vinyl ester and an ethylenically unsaturated carboxylic acid or a derivative thereof.
