Peel adhesion to paper—interpreting peel curves

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 …
