Experimental evaluation of the decohesion process of adhesive joints on polymer films
Abstract
Acrylic adhesive/PE film joints were prepared by using PE films preactivated by corona discharges. The tear-off work, a measure of strength of the joint, is the sum of several terms; the major terms include the work of adhesion and the work of deformation (here: stretching of film) involved in the tear-off process. The tear-off work (P0, Fig. 5) and the stretching work (Pr, Fig. 6) were determined for films that varied from 50 to 150 |am in thickness, in relation to specific treatment energies (Ej) ranging up to 7.5 kj/m2. Within the interval 0 <= Ey <= 3 kJ/m2, P,. rises in an approximately linear way. As Ej is increased, evaluation of the unit adhesion work from tear-off tests becomes more and more burdened with error. Within the range of Ej- adopted in technical preparation of upper layers of PE films (Ej = 2 kJ/m2), the error is kept within 9% and is only slightly related to film thickness.
