Abstract: A package is formed of a molded sheet (1) of a thermoplastic synthetic resin having a plurality of pocket-shaped molded portions (2) formed in one surface thereof, with an object (T) to be packaged accommodated in each of the pocket-shaped molded portions; and a sealing sheet is bonded to the other surface of the molded sheet so as to seal off openings of the pocket-shaped molded portions. A deposit layer (4) of an inorganic oxide such as a silicon oxide is formed on one or both of the inner and outer surfaces of each pocket-shaped molded portion (2). The deposit layer (4) compensates for thinning of a top wall (2a) and peripheral edge (2c) of the pocket-shaped molded portion (2), caused by the molding process, to increase the barrier capability thereof.

Abstract: An indicator composition for ethylene oxide gas comprises 4-(4-nitrobenzyl) pyridine, nitrocellulose, a basic substance, and, optionally, a blue coloring agent.The indicator composition, when exposed to ethylene oxide gas, changes its color to develop a stable color indication, typically of a green color. The composition can take any shape and form, and is typically applied to a substrate such as paper to form a layer thereon.
