Abstract

Abstract A protective liner which is temporarily, but securely, held to the interior crotch portion of nether garments by a thermoplastic, pressure-sensitive adhesive pattern bonded to a thermoplastic protective film provided on the under surface of the liner. The thermoplastic, pressure-sensitive adhesive is permanently fused to the protective film thus preventing delamination of the pressure-sensitive adhesive patterns from the film, and the adhesion level of the pressure-sensitive adhesive is such as to temporarily, but securely, adhere the protective liner to the crotch portion of the nether garment. The thermoplastic adhesive pattern is indirectly applied to the thermoplastic adhesive barrier film to prevent basic distortion of the film which would render it unfit for its intended protective function.
