Abstract:

A higher standard for medical packaging materials can meet a requirement for packaging safety, sterility, and multiple sterilization compatibility in various application scenarios. Therefore, high⁃density polyethylene non⁃woven packaging materials with robust properties fabricated by the flash⁃spinning process have attracted tremendous attention from academic and industrial fields. This review introduced the selection of solvent systems, specific process flow, basic principles of phase separation, and solvent supersonic steam flow in the flash⁃spinning process. Meanwhile, the domestic flash⁃spinning⁃related techniques and corresponding non⁃woven materials were discussed in detail. Moreover, the parameters and evaluation criteria of Du Pont Tyvek® serial products were summarized, and the application performance of the materials was analyzed. This may provide theoretical and technical references for the development of the flash⁃spinning process and medical non⁃woven packaging materials.

Key words: medical packaging material, non?woven material, flash?spinning process, product analysis
