Ensuring Container Closure Integrity (CCI) for Products requiring Deep Cold Storage by correlating Seal Quality to CCI
As described in the chapter subsection USP <1207.3> Package Seal Quality Test Methods, the measurement of residual seal force (RSF) indicates the quality of the vial package seal, giving insight into the quality of the sealing process. Correlating RSF to CCI data enables optimization and validation of the vial sealing process with parameters that give assurance of good CCI. This Case Study describes how science-based statistically valid RSF data was generated on the vial sealing process and combined with CCI data to ensure good CCI of sterile product needing deep cold storage
