Tyvek® 미생물 장벽 테스트 결과
Per ASTM F1608. Microbial barrier is the measure of the ability of a porous substrate to prevent bacteria penetration. A completely impermeable control sample (microbial penetration is zero) is challenged with one million or 106 colony. forming units (cfu). The number of cfu 106 has a log10 value of 6. If a sample challenged in the same way as the control allows 10 cfu (log 10=1) to penetrate, then its log reduction value (LRV) is 5 (6–1=5). Therefore, the higher the LRV, the more resistant the packaging is to bacteria and microorganisms.
Tyvek® 원단 SEM 사진
The unique structure of Tyvek®, which creates a tortuous path with substantial lateral movement, results in superior microbial barrier properties.
