Turn the question into a controlled engineering duty
Qualify cap, liner or can end with formula, pressure, thermal history, opening and market use. The acceptance basis must resolve product chemistry and gas state together with closure, liner or coating, then assign operating limits, responsible roles and controlled records for this exact task. Control formula ownership, ingredient legal status and potency, allergen or occupational hazards, declared nutrients or actives, analytical methods, product stability, package route and market-specific labeling responsibility. Fix serving and batch calculation units, supplier assay conventions, weighing tolerances, premix recovery, process-retention evidence, blend and pack sampling locations, label revision and unauthorized-substitution response before low-dose materials enter production. Record every input with units, source, approval status, credible range and decision owner. Keep an unknown visible when it can change sizing, hygiene, packaging, automation, utilities, cost or schedule.
