compression burst test iconCompressive Burst Testing

Sometimes the only required measure of a package’s strength for stacking, is its resistance to bursting under compression. Unlike a top-load or crush test, failure is detected as a sharp drop in resistance under compression, and can be a valuable test for sachets, pouches and plastic tube containers. Caps, closures and seals can be independently tested, but the overall integrity, or weakest point for a filled container remains a practical consideration.

In the case of contaminating or sterile contents, sophisticated leak detection down to molecular level may be required. For all others, simple pressure from a non-puncturing plate or cylinder, with adequate containment can be enough.

The test is one of simple compression and break detection. This may be a sharp break for either very fluid contents or catastrophic failure, or a percentage break detection for more viscous contents or gradual failure.
