Compliance:ISO GMP FDA
Application: 121℃ steam sterilization packaging for rubber stoppers, glass vials, cleanroom PPE, surgical instruments, dental tools, pharmaceutical components, and lab glassware.
Key Features: 100% pressure - hold + dye leak testing, low - endotoxin (<0.25 EU/mL), lint - free opening (≤10 particles ≥5μm), steam indicator (color - change confirmation), cost - saving vs side - seal alternatives, single - use sterile barrier.
Custom Options: Size
Pharmaceutical, hospital, and lab steam sterilization workflows often need cost - effective packaging that works for 121℃ steam, ensures sterile barrier, and enables easy opening—while avoiding over - specification for high - temp (134℃) processes. Traditional side - seal Tyvek bags are pricey for large - batch use, and generic paper bags lack durability or reliable microbial barriers, risking contamination or seal failure.
Our Center - Sealed Tyvek Steam Bags combine affordability with Tyvek’s proven performance, tailored for 121℃ steam sterilization (NOT for >121℃). The center - sealed back seam simplifies production to cut costs without compromising seal integrity; the Tyvek 1073B side ensures rapid steam penetration and blocks ≥0.2μm microbes, while the HDPE clear film enables visual inspection and forms a clean, easy - peel seal with pre - cut notches for tool - free, lint - free opening in sterile environments.
These bags are perfect for rubber stoppers (preserves elasticity), glass vials (shock absorption), PPE (maintains sterility), and surgical instruments (resists cuts from sharp edges). Each bag has a steam indicator that changes color post - sterilization and undergoes 100% leak testing. Made in an ISO Class 7 cleanroom, they meet low - endotoxin, low - particulate, and biocompatibility standards, fitting GMP traceability needs at a budget - friendly price point—ideal for high - volume, 121℃ steam sterilization workflows.
