Precision Clean Breather Bags®
Precision Clean Breather Bags® are designed for sterilization of products used in cleanroom environments. Precision Clean Breather Bags have excellent porosity for enhanced cycle times and are manufactured with the strongest Tyvek®-bonded seals available. Precision Clean Breather Bags are manufactured from ultra-pure and clean resins with one side of 1059B (or 1073B) Tyvek and one side of .003" Precision Clean® High Density film, or two sides of Tyvek material in our ISO Class 4 Clean Room.
To ensure the highest standards of traceability and quality, each order is manufactured from its own exclusive base of raw material, which is tested regularly for leachables, extractables, and off-gassing characteristics. Each manufacturing job is tested for particle content and certified with a letter of conformance.
PCBB is available printed, unprinted, and is suitable for gamma, steam, or ethylene oxide sterilization.
