WRAPPER AND METHOD OF MANUFACTURING THE SAME

摘要

A wrapper consisting of a molding sheet (1) of a thermoplastic synthetic resin having a plurality of pocket-like molding portions (2) on one surface thereof with objects T to be wrapped, such as medicine held in the pocket-like molding portions (2), and a closing sheet bonded to the other surface of the molding sheet (1) and closing the openings of the pocket-like molding portions (2), wherein a deposit layer (4) of an inorganic oxide, for example, silicon oxide is formed on the outer or inner surface or both surfaces of the pocket-like molding portions (2). The deposit layer (4) reinforces top walls (2a) and circumferential edges (2c), the thicknesses of which become smaller during a molding operation, of the pocket-like molding portions (2), and increases the barrier effect.
