Abstract: An adhesive tape that includes: a first adhesive layer defining an upper surface of the tape; a second adhesive layer defining a lower surface of the tape; and a reinforcement layer (or first and second reinforcement layers) and a thermally activated layer between the first adhesive layer and the second adhesive layer. The thermally activated layer is a thermoplastic polymer layer. The thermoplastic layer may be made of ethylene-vinyl acetate copolymer, modified polyolefin, ethylene acrylic acid copolymer, ethylene terpolymer, polyamide copolymer, poly(trans-1,4-isoprene), polyethylene oxide, or a combination thereof. Further, the thermoplastic layer may exhibit a melting point from 60° C. to 150° C. and may have a molecular weight from 1,000 to 1,000,000.
