Four Sided Seal Tester

摘要

Four Sided Seal Testing is an alternative method that can be used to test the seal strength of Combat Ration Pouches. This method allows the food to remain in the pouch while the seals are being tested and all four seals of the pouch are tested at the same time. This method is quicker and uses less pouches and thus results into cost savings. This project studied the interaction of the plate gap and the burst strength of a pouch. By using this relationship, a revised internal pressure specification for MREs that allows a wider confinement plate gap than 0.5 inch was developed. In addition, minimum required seal strength of the Institutional Sized Retort Pouch was determined that assures the pouch to survive the typical shipping abuse tests.
