Abstract
Disclosed is a double-faced pressure-sensitive adhesive tape which includes a foam substrate, one pressure-sensitive adhesive layer arranged on or above one side of the substrate, and another pressure-sensitive adhesive layer arranged on or above the other side of the substrate. The adhesive tape has a total thickness of 250 μm or less. The adhesive tape is thin but highly waterproof (sealable against water). The adhesive tape preferably has a tensile strength of 0.5 to 20 MPa for further superior processability.
