How much force does it take to break OPP tape, and how far does it stretch before rupture? This YG Group guide walks through an OPP tape tensile test with reference to ISO 29864:2018, Method A. It shows how to prepare and align specimens, pull them to rupture, and determine breaking strength and elongation at break.

Holding power shows how well a pressure-sensitive adhesive tape resists movement under a sustained shear load. It is different from initial tack and peel adhesion because it focuses on how the bond performs over time while a constant load is applied parallel to the bonded surface.

A practical guide to automotive masking tape peel adhesion from its own backing, explaining ISO 29862:2024 Method 2, specimen conditioning, tape application, 180° peeling, repeatability controls, and how to interpret the test result.

Learn how YG Group evaluates masking tape initial tack using the rolling distance method under GB/T 4852-2002 Method B, including test conditions, specimen preparation, the 21°30′ inclined trough, No. 14 steel ball, result calculation, and key factors affecting accuracy.
