Medical Pouch Heat Seal Joint Tensile Test

Specification


Rocket Medical PLC are award winning designers and manufacturers of medical devices for a wide range of clinical applications. These medical devices are packed into prepurchased pouches and sealed in-house before being sent offsite for sterilisation. The heat seal on these pouches must conform to British Standard BS EN 868-5:1999 (Packaging materials and systems for medical devices which are to be sterilised). Wishing to perform this test themselves, Rocket Medical sought a test system, which could accurately confirm that the strength of each heat seal joint was not below 1.5 N per 15 mm width before and after undergoing the sterilisation process.


Solution


Mecmesin provided an Imperial 1000N test system (now superseded by the MultiTest-i range), a 250 N loadcell and lever-operated serrated cam grips.To perform the test, 15mm width strips are cut at right angles to the heat seal joint at the mid-point of the pouch. Each end of the strip is then clamped into opposing jaws on the test stand with the tail unsupported. The seal is tested at a rate of 200 mm/min ±10 mm/min and the maximum force recorded. The computer-controlled test system offered Rocket Medical full programming capability. The system displays the maximum force achieved during the test, as well as the average maximum force incurred over a number of tests. This saves the company a significant amount of time when performing tests and provides them with a means of guaranteeing compliance with the relevant standards.


Testimonial


‘In order to meet the British Standard regarding heat seal strengths on medical pouches, Mecmesin provided an operator-friendly system, which displays data in graphical format to clearly show compliance to the standard.’

A Brand You Can Trust

"The MultiTest 0.5-i is a very good and reliable machine and the Emperor™ Software brings great advantages. It’s a very useful tool for these kinds of tests. It’s fully programmable and offers an in-depth analysis of results. It’s a precious tool for everybody involved, especially those who work with plastics and their mechanical performance"

Nikos Michopoulos, Quality Control, Eurofilm Mantzaris S.A.
