Meaning
Evaluation protocols determine if a container can protect its contents while remaining free from hazardous chemical migration. Package safety testing involves subjecting the final assembly to controlled conditions of temperature and time to simulate its life cycle.
Migration Study
Lab technicians place the material in contact with food simulants to measure the movement of molecules from the plastic to the product. Using package safety testing ensures that any chemical transfer remains below the legal limits set by health authorities. These limits are based on toxicological data and expected consumption patterns.
Stress Resistance
Mechanical trials verify that the container can withstand the physical rigors of transport and storage without leaking. A failure in package safety testing might reveal a design flaw or a weakness in the choice of resin. These tests include drop tests and compression tests to evaluate the structural integrity of the part.
Shelf Life
Long term stability is measured by observing how the material interacts with the product over months or years. If the plastic degrades or the barrier properties fail, the contents may spoil before the expiry date. This testing is necessary for products with long storage requirements such as bottled water or canned goods.
