For guaranty of quality of the non-based adhesive sheet such as adhesive used in flat panel display (FPD), damage of adhesive in a laminate process should be clarified. Standard peel tests are not suitable for evaluating the interfacial strength because measured peel force includes other influences of peeling. In this paper, the peel strength is measured in the range from 30 to 180 degrees of the peel angle and 20 to 1000mm/s of peel rate by using two-axes-driven peel method developed. Unstable peeling occurred in the case of small peel angle while the failure of adhesive layer occurred in case of high peel rate. Peeling behavior map is constructed from the results of two-axes-driven peel test. It is shown that the results obtained by the Y-type peel test coincide with the classifications of the peeling behavior map.
