The opening torque on containers fitted with child-resistant closures (CRCs) is measured with a Vortex-d motorised torque tester with a top-load capability for applying set loads during torque testing. Using a motorised torque testing system ensures repeatable and accurate test results, in comparison with manual torque testers.  The Vortex-d has been superceded by the Vortex-dV.

Top load testing of PET bottles can be dome swiftly and accurately with the MultiTest-dV from Mecmesin.  The test stand can be set to load the bottles to 1/4" at speeds up to 20" per minute.  Results can be send to a connected printer, or VectorProTM Lite software can capture all the data. 

This video show a MultiTest 5-xt touch-screen controlled force testing stand being used to test PET bottles for "Top-load". The resistance to crush testing is found together with the individual bottle height. Immediate colour-coded indication of "Pass" or "Fail" is given on the touch-screen. This is an important test in the "downgauging" or "lightweighting" of packaging materials. This is to reduce the amount of material used, reduce costs and to meet environmental standards, but at the same time ensuring the packaging does not fail during the filling, capping and storage process.

This video shows how to set up the MultiTest-xt to measure the height of different sized bottles while at the same time performing a top-load or crush test. The favourite buttons on the touch-screen are used to set the "Home" and "starting position" for each different size of bottle automatically. Upper and lower limits can be entered for both the bottle height and its performance under load, with unambiguous, colour coded "Pass" or "Fail" indication.

A 'trouser tear' test to measure tear propagation resistance is carried out using a FPT-H1 horizontal friction peel tear tester adn lightweight tear grips.  The FPT-H1 is suitable for testing to a range of tear testing standards including ASTM D1938-2, BS EN ISO 6383-1 and BS EN ISO 13937-2.
