Context & Assumptions

Container Closure Integrity Testing (CCIT) is a critical quality assurance procedure used to verify the hermetic seal of metal cans in the food and pharmaceutical industries. By assessing seam overlap and internal vacuum, engineers ensure the packaging provides an effective barrier against microbial contamination and spoilage.
