The formula model of the performance of adhesive to the composition was presented and a groupof relative program was designed for assisting to optimise the adhesive formulation. This program canbe used to perform regression analysis for multi - ingredient experiment system to obtain fitting function and to plot the contour and relational curves of the fitting function. The isograms of peel strength,rool tack force and holeing time of SIS PSAs were obtained by the program. The peel strength wasmainlg effected by the content of tackifier and the rolling ball tack force was mainly effected by plasticizer and the holding time by SIS.
