Summary of Flexible Package Integrity Testing With and Without Restraining Plates

ASTM F2095 standard testing covers the measurement of leaks in nonporous film, foil, or laminate flexible pouches. The enclosed material should not come into contact with water, oils, or other liquids.

F2095 flexible package integrity testing detects leak rates in flexible packages. However, the leak rate is dependent on package volume as tested. Two test methods are explained below. It should be noted that the methods are destructive in that they require entry into the package.

Conditions should be used to obtain the same temperatures that exist on the test apparatus. Samples are made to allow the operator to refer to the specific test samples while recording test information and results.

ASTM 2095 Flexible Package Laboratory Testing Procedures

Test Method A, pressure decay leak test allows the packages to be tested without restraint. Within test method A, the pouch, tray, or other type packages will contain a volume of air. This is defined by its mechanical configuration and its ability to resist the internal pressure applied. The ASTM F2095 test method requires the package to be at a stable volume configuration.

On the other hand, Method B allows the use of rigid restraining plates against the walls of the package. This helps limit the volume while stabilizing the package volume. ASTM F2095 method B provides a standard to establish reports to find failures within the lab rather than within the field. It is used to detect small leaks rapidly in flexible seals or walls.

Significance of ASTM F2095 Pressure Decay Testing

Observed changes in pressure indicate leakage paths in the package seals or pinholes in the surfaces. This leak may be found and displayed in decay pressure units or calculated leak rate units.

The use of calibrated hole sizes or orifices may be appropriate to determine leakage sensitivity or barrier integrity for these materials. Though theoretical leak rate sensitivity can be established, the measuring instruments and pressure units must be calibrated, certified, and verified.

The report includes general information such as date, time, location, and test engineer. Details of the package include the type of material and other characteristics. The number of packages tested and the number of failures are recorded, as well as any conditioning.

Specific information from this report consists of the package type, size, and materials. In addition, the report should include whether the package was tested empty or filled with product, conditioning parameters, and environmental conditions at the time of the test.
