Specification
Award winning medical device designers and manufacturers, Rocket Medical PLC, produce a large variety products for clinical applications, which are packaged in pre-produced pouches, sealed in their manufacturing plant and then sent for sterilization.
Systems and packing materials for medical devices that will be sterilized, must be produced with heat seals that conform to BS EN 868-5:1999. The heat seals on Rocket Medical PLC’s pouches also had to conform to this standard.
Rocket Medical, wanted to bring this test in-house, so looked for a test system which could be used to accurately check that the strength of every heat seal joint before and after sterilization didn’t fall below 1.5 M per 15 mm.
Solution
Medical pouch peel test
An Imperial 1000N test system was supplied by Mecmesin (which the OmniTest range has now replaced), along with lever-operated serrated cam grips and a 250N loadcell.
The test procedure consists of cutting 15 mm width strips at right angles to the heat seal joint, which is at the mid-point of the pouch. The test stand’s opposing jaws are then clamped to each end of the strip, with an unsupported tail; a T-peel test.
Rocket Medical PLC, had full programming capacity due to the computer-controlled test system. The maximum force of the seal is recorded with the testing rate set at 200 mm/min ±10 mm/min.
The system shows the average maximum force achieved over a number of tests as well as the maximum force of the current test. Compliance with relevant standards is guaranteed, while also being a significant time-saving measure.
System
- Lever-operated cam grips (serrated)
- Loadcell 250N
- Imperial 1000N (now superseded by the MultiTest 1-i)” to “Imperial 1000N (Superseded by the OmniTest 1 universal testing machine)
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.”
