The permeability of water vapor in a composite film [a Mylar (trademark of DuPont, Inc.) film coated with a pressure sensitive adhesive on both sides] and a Mylar film (type D) have been determined at 23°C. The water vapor permeability in the pressure sensitive adhesive, Flexbond 150 (a trademark of Air Products and Chemicals), and the Mylar film have been found to be 3.23 × 10 −7 and 2.30 × 10 −8 cm 3 (STP) cm · cm −2 · s −1 · (cm Hg) −1 , respectively, at 23°C.
