Disposable medical devices are often preferred by medical professionals as they eliminate the need for sterilization and improve pateint safety. However, the responsibilty for sterilation is a major concern for the medical device companies manufacturing these disposable devices. Packaging must be considered and a shelf-life must also be recommended. A medical device company asked us to provide a testing solution to help determine the seal strength of medical packaging.
Using three different samples of medical packaging that were prepared into 1-inch wide specimens for testing, we evaluated the seal strength of the packaging in a 180 degree peel test as described by ASTM F88: Standard Test Method for Seal Strength of Flexible Barrier Materials. The purpose of the testing was to determine if there was a difference in seal strength as a result of different combinations of packaging materials and adhesives.
Our test configuration consisted of a 3345 universal testing system
configured with a 50 N (11 lb) load cell and 250 N (50 lb) capacity pneumatic side action grips
with rubber-coated faces. The rate of grip separation was set to 300 mm/min (12 in/min).
