Evaluation of substrates for 90 degrees peel adhesion--a collaborative study. I. Medical tapes.

As part of a method development for peel testing, an interlaboratory comparison among Food and Drug Administration-Center for Drug Evaluation and Research, Food and Drug Administration-Center for Devices and Radiological Health and Southwest Research Institute was conducted using medical tapes. The aim was to determine which readily available substrate [stainless steel (SS), high density polyethylene (HDPE) or Vitro-Skin(R)] would best distinguish among various medical tapes. Five medical tapes (3M 1523, 3M 1525L, 3M 1776, Mepiform(R) and Mediderm(R) 3505) were evaluated on four different substrates (SS, HDPE, Vitro-Skin, and human cadaver skin) using the following peel parameters: approximately 3 min dwell time, 90 degrees peel angle, and 300 mm/min peel rate.
