Test bubble mailer quality with these practical cushioning and air retention checks.
Practical tests
Testing methods0 / 4 checked
Quick answer
Quality bubble lining springs back instantly when compressed, resists popping under moderate pressure, retains air overnight, and protects items in a 60cm drop test. Test 5-10 samples from any new supplier or batch. If bubbles flatten slowly, pop easily, lose air overnight, or fail the drop test, the quality is insufficient. Reject the batch and try a different supplier.
Interpreting results
Bubbles should recover immediately, not slowly.
Quality bubbles resist moderate pressure.
Bubbles should retain volume for weeks, not hours.
Specs: specifications or cushioning science.
When to test
Test samples before every bulk order. Test when switching suppliers. Spot-check batches on delivery. Test older stock before use to confirm air retention has been maintained.
