Relationship between seal strength and burst pressure for pouches

Based on force analysis, the seal strength obtained from the peel test is equivalent to the product of the burst pressure and half of the plate separation obtained from the burst test. To verify this relationship peel tests and burst tests were performed using MRE pouches. Good agreement between the observed and predicted values was observed when the peeling times of the two tests were the same. This relationship is useful for comparing the performance of the two tests, as well as for establishing criteria for destructive and non‐destructive testing.
