Abstract
A pipe liner bag includes a tubular resin absorbent material formed from a sheet of such material. Opposing ends of the sheet is seamed together to form the tubular shape. A hardenable resin is impregnated in the resin absorbent material. A seam protection tape covers an outer surface of the seamed portion. An air-tight plastic film covers the remainder of the outer surface. A sealing ribbon tape, which is larger than the seam protection tape, is affixed over the seam protection tape to air-tightly seal the seamed portion.
