PURPOSE: To obtain medical supplies which are stable in use and disintegrable by water when discarded, by using printing faces and a water-disintegrable pulp sheet, a printing face having a specified value of opening ratio by a printing ink containing hydrophobic polymer as a permeable layer of liquid component, a printing face having a specified value of opening ratio by a printing ink containing water-soluble polymer, and a water-disintegrable pulp sheet.
CONSTITUTION: As a permeable layer 1 for liquid component, there are used a printing face 6 having an opening ratio of 40-60% by a printing ink containing hydrophobic polymer, a printing face 7 having an opening ratio of 40-60% by a printing ink containing water-soluble polymer, and a water-disintegrable pulp or fibrous sheet 8, and as an absorptive layer 2 water-disintegrable pulp containing highly absorptive polymer 10 or a fibrous sheet 9 is used, as necessary. Also, as a leakage-proof layer 3, a water-disintegrable pulp or fibrous sheet where a water-soluble polymer film is laminated or where a water-soluble polymer is applied impregnated is used. Then, the peripheries of these are adhesively bonded. Further, as a removable paper 13 for a tacky adhesive, a water- disintegrable paper is used.
