In a preferred embodiment of the present invention, the pore size of the microporous membrane is 0.2-0.3 microns. In the present invention, the pore size of the microporous membrane should meet the shape characteristics of the virucidal agent. For example, when the virucidal agent is in powder form, the pore size of the microporous membrane should be sufficient to allow the released pharmaceutical gas to pass through the microporous membrane, and at the same time, the virucidal agent will not leak.

In a specific embodiment of the present invention, the thickness of the microporous membrane is 0.01-0.05mm, 0.01-0.04mm, 0.01-0.03mm, 0.01-0.02mm, 0.02-0.05mm, 0.02-0.04mm, 0.02-0.03 mm, 0.03-0.05mm, 0.03-0.04mm, or 0.04-0.05mm.

In a specific embodiment of the present invention, the material of the microporous membrane includes, but is not limited to, a plastic film; preferably, the material of the microporous membrane is a PTFE film.

At the same time, the aggregates should be easily hot-melt bonded to prevent the leakage of the virucidal agent. Therefore, the material of the aggregate is not particularly limited, as long as it does not react with the virucidal agent.

In a specific embodiment of the present invention, the aggregate material comprises a skin-core layer composite material. In the present invention, the pharmaceutical package needs to be heat-sealed, and thermal bonding is achieved through the skin layer, and the bonding temperature is higher than the skin layer and lower than the core layer; in the present invention, the core layer provides strength). For example, the material used for the core layer is polyethylene terephthalate (PET), and the material used for the skin layer is polyethylene (PE).
