Description

Technical Field

[0001] The utility model relates to the technical field of packaging structures, in particular to a sterile filtration membrane separation type packaging. Background Art

[0002] Sterile filtration membranes are mainly used to filter fats, oils and water. The main structure of the sterile filtration membrane is a flexible membrane cloth material. In order to enhance the performance of the filter membrane, such as improving the filtration efficiency, reducing the clogging of the filter membrane (anti-adhesion), or improving the compatibility between the solution and the filter membrane, the membrane cloth can be soaked with a surfactant. Surfactants are mostly photosensitive and need to be stored in a cool place and protected from light to avoid degradation of the surfactant. The membrane cloth needs to be in a dry and sterile environment for long-term preservation. Due to the difference in the environment for long-term preservation of the two materials alone, in the prior art, when used, the membrane cloth is soaked with a surfactant or a pre-treated wet filter membrane is directly used. The first method is inconvenient to use, and the second method has a short storage time. Utility Model Content
