Peel adhesion to paper—interpreting peel curves

Abstract

Peel experiments involving three PSA tapes and three paper substrates were employed to develop a general approach for the analysis of peeling from paper. Plotting the logarithm of the peak peel force (i.e. the maximum value) versus the logarithm of the peel rate yielded a generalized peel curve which illustrated transitions from interfacial to paper failure. The general peel curve consisted of linear segments (on the log/log plots) which intersected when the failure mode changed from interfacial to paper failure. The influence of paper type, PSA type, and peel angle on the generalized peel curve was determined.
