Liquid-absorbing barrier bag with adhered swelling absorbent

A liquid-absorbing barrier bag comprising:

• a liquid-permeable envelope having an inner surface;
• an adhesive disposed on the inner surface of the liquid-permeable envelope;
• and
• a liquid-absorbing material adhered to the inner surface of the liquid-permeable envelope by the adhesive, the liquid-absorbing material characterized in that it expands upon contact with liquid;
• wherein the liquid-absorbing material separates from the inner surface of the liquid-permeable envelope upon absorption of liquid;
• whereby upon expansion of the liquid-absorbing material, passage of liquid through the liquid-absorbing barrier bag is precluded.

A liquid-absorbing barrier bag comprising:

• a liquid-permeable envelope having an inner surface;
• an adhesive disposed on the inner surface of the liquid-permeable envelope;
• and
• a liquid-absorbing material in powdered or granular form adhered to the inner surface of the liquid-permeable envelope by the adhesive, wherein the liquid-absorbing material is characterized in that it expands upon contact with liquid to form a gel;
• wherein the liquid-absorbing material is characterized in that it absorbs from 50 to 1000 times its weight in liquid;
• wherein the adhesive is characterized in that it releases the liquid-absorbing material from the inner surface of the liquid-permeable envelope upon absorption of liquid;
• and
• whereby upon expansion of the liquid-absorbing material, passage of liquid through the liquid-absorbing barrier bag is precluded.
