Making sure that things are sticking around

When surgical drape materials were not adhering to a patient’s skin, this caused the manufacturer to believe that the materials being used were not the correct combination for the application. The adhesive was not bonding well to the non-woven drape. To further aggravate the situation, the pressure sensitive adhesive (PSA) was being removed from the drape when the release liner was taken off.

When M&C conducted a Total Process Analysis (TPA), it was confirmed that the PSA being used for the application was incorrect. M&C’s Material Selection Analysis Team determined the proper combination of substrate and adhesive required to prevent field failures. The team also developed a more effective design for the application.
