The present invention provides an adhesive sheet that is extensible and conformable. The sheet comprises a non-creped flatback paper backing comprising cellulosic fibers and an elastomeric saturant and having an elongation at break of at least 8 %; and an adhesive coating on at least a portion of at least one major surface of said backing. No mechanical means is used to generate extensibility or conformability in the backing of the adhesive sheet of the invention. The adhesive sheet combines all the advantages of a smooth flatback tape and the extensibility and conformability of a creped or microcreped tape.
