Abstract: A low-adsorptivity packaging bag equipped with a sealant layer that satisfies all of the following: heat-sealability, low adsorptivity, cuttability, and water-vapor barrier properties. A low-adsorptivity packaging bag for storing contents containing a low-molecular-weight volatile compound, in which a layered body provided with a substrate layer including one or more layers and a sealant layer containing a cyclic olefin resin having a glass transition temperature of 50-190° C., inclusive, is formed as a result of heat-sealing with the sealant layer side as the inside surface thereof.

Abstract: A non-woven fabric that absorbs only a small amount of volatile low molecular weight compound, and that has good texture when used as a non-woven fabric that makes contact with human skin. This thermal bond non-woven fabric containing cyclic olefin resin includes at least: fibers (A) containing at least 50 mass % of a cyclic olefin resin (A1) having a glass transition temperature TgA1° C.; and fibers (B) containing at least 10 mass % of either a cyclic olefin resin (B1) having a glass transition temperature TgB1° C., or a crystalline thermoplastic resin (B2) having a melting point MpB2° C.; the fibers (A) and the fibers (B) being heat-spliced together; wherein TgA1>TgB1 or TgA1>MpB2, and either the difference between the glass transition temperature TgA1° C. and the glass transition temperature TgB1° C. or the difference between the glass transition temperature TgA1° C. and the melting point MpB2° C. exceeds 20° C.
