Abstract

PURPOSE:A packaging sheet having a simple structure and capable of controlling the rate of sublimation of a sublimable drug thereby keeping the drug effect for a desired period, by packing a sublimable drug with a packaging sheet composed of a breathable sheet and a desired amount of a permeability-controlling agent scattered and attached to one surface of said breathable sheet. CONSTITUTION:A desired amount of a permeability controlling agent 2, 2', composed of powders of a thermoplastic resin such as polyolefin, etc. is scattered in spots to one surface of a breathable sheet 1 such as Japanese paper, nonwoven fabric, etc. to obtain a packaging sheet 10. A sublimable drug such as formed or granular insecticide, e.g. camphor, p-dichlorobenzene, etc. a deodorant, a perfumery, etc. are sealed with said packaging sheet 10 by heat-sealing 41, 42, 43. Since the sublimation of the sublimable drug sealed with said sheet is nearly inhibited through the part covered with the permeability controlling agent, a major part of the drug sublimes through the part free from the controlling agent, and accordingly, the rate of sublimation can be controlled by controlling the amount of the controlling agent. The use of a thermoplastic resin enables the easy and economical automatic packaging.
