Abstract
A water-degradable carrier for holding a caustic substance includes a tube having a first end, a second end, and a hollow interior disposed between the first and second ends. The tube may be formed from a water-degradable material and have overlapping self-adhered windings. The water-degradable material may include a water-degradable paper layer and a chemical-resistant water-degradable film layer that acts as an adhesive when wetted to adhere together the windings. The chemical-resistant water-degradable film layer is selected from a material that is resistant to a caustic substance that is to be carried by the carrier and acts as a barrier to substantially prevent the caustic substance from degrading the water-degradable paper layer and leaking out of the tube.
