Abstract
This invention provides a double-faced PSA sheet comprising a substrate film having first and second faces, and first and second PSA layers provided to the first and second faces of the substrate film, respectively. The first and second PSA layers have a combined thickness TPSA and the substrate film has a thickness TS at a TS/TPSA ratio value of 0.3 or less. The first and second PSA layers individually have a storage modulus G′(apply) of 0.6 MPa or less at a temperature at which the PSA sheet is press-bonded to an adherend.
