Peeling Test for Adhesive Tapes (Standard ISO 29862, JIS Z 0237, ASTM D3330)

Adhesives using synthetic polymers as raw materials have been commercialized. These adhesives are often used in a variety of industrial fields, including electronics and electrical machinery. This article introduces an example of a 180° peeling test for adhesives used in adhesive tapes.

The sample was an ordinary adhesive tape cut to a width of 24 mm and a length of 300 mm; it was set on a stainless steel plate. An end of the tape was gripped and the tape was folded back 180° so that the back sides of the tape contact each other. Then a 25 mm length of tape was peeled from the plate. The end of the plate where the tape was peeled off was fastened to the lower jig attached to the tester, and the adhesive tape was fastened to the upper jig.

ASTM D3330 also includes several other testing methods, each tailored to specific types of adhesive tapes:

Method B: 180° peel test for measuring the adherence of a single-coated tape to its backing.

Method C: 180° peel test for measuring the adhesion properties of double-coated tapes.

Method D: 180° peel test for measuring the adherence of the release liner to the adhesive of either single or double-coated tapes.

Method E: 180° peel test for adhesive transfer tapes, which do not have a backing material.

Method F: 90° peel test for measuring the adhesion properties of single-coated tapes.
