Burst Strength

ASTM F2054 Standard Test Method for Internal Pressurization Failure Resistance of Unrestrained Packages

Industry Application

Burst testing is an alternative method to evaluate seal strength. It is important to note that this application is ideal for packages where you are making all seals, not just a closure seal. Some examples would be a thermoform tray or a form-fill-seal application. Burst testing is typically more attractive for in-process testing because it is faster than other methods. A limitation to burst testing is the inability to trend seal strength of a specific package location over time. PCL has the ability to perform restrained and unrestrained burst testing.
