Testing for Container is a critical quality control activity for manufacturers and users of rigid packaging, especially when containers are used to transport liquids, chemicals, or hazardous goods. Even when containers are shipped empty, structural defects or improper closures can cause leakage risks once pressure differences occur during air transport or storage.
