PCT No. PCT/JP93/00892 Sec. 371 Date Aug. 17, 1993 Sec. 102(e) Date Aug. 17, 1993 PCT Filed Jun. 29, 1993 PCT Pub. No. WO94/02317 PCT Pub. Date Feb. 3, 1994.A thread-reinforced paper sheet comprises upper and lower paper layers and a reinforcing thread interposed therebetween. A thread-reinforced gummed tape comprises a tape base material which consists of upper and lower paper layers and a reinforcing thread interposed between the upper and lower paper layers, and a moisture activated adhesive layer formed on one of surfaces of the tape base material. In each of the thread-reinforced paper sheet and the thread-reinforced gummed tape, a water-soluble or water-dispersible adhesive is used to laminate the upper and lower paper layers, and a water-soluble thread is used as the reinforcing thread. Each of such thread-reinforced paper sheet and such thread-reinforced gummed tape exhibits a strength equivalent to that of the prior art article and moreover, has a complete disintegratability. Thus, a regeneratable thread-reinforced paper sheet as well as a regeneratable thread-reinforced gummed tape is provided.
