Peel-off test on a packaging beaker withaluminium cover With the flexible testing unit for peel-off testing on food stuffs beakers (e.g. joghurt, soft cheese, coffee cream,...), the peel-off forces which are required to open a glued beaker cover can be determined. Various sizes and shapes of beakers can be held with the variably adjustable unit. A clamp is affixed to the pull- off tab of the cover. This is connected to the industrial load cell on the moving crosshead with a thin cord via a guide roller. When the moving crosshead is driven upwards, the cover is peeled-off and the force required is determined. Testing of metal packagingCompression testing of metal barrels, cans,canisters etc. The compression tests on metal barrels, canisters etc. are defined in various directives (e.g. the directive for production and test standards for packaging, large packing items, large packagings...). Accordingly, industrial metal containers must be loaded for 5 minutes with a force that is equal to 1.8 times the maximum gross mass weight with which such a packaging is allowed to be loaded. The packaging is not allowed to have any permanent deformations after the test is over. Often, it is also of interest to determine the maximum possible loading of a packaging unit. Here the packaging unit is loaded until failure and the maximum load required for this is determined.
