Puncture strength, haze, Tg, extracts, and permeation rates are all single-use bag attributes about which end-users want data. While these are important characteristics, they are polymeric material properties that may or may not indicate actual bag performance. Ultimately, an end-user wants to know that the single-use bag will not put their process fluid at risk. This presentation will share pH stability data from frozen sodium phosphate solution stored in single-use bags with different gas permeation rates that are subjected to CO2 gas from sublimating dry ice.
