Analysis of New Flame Treatment Technology for Surface Modification and Adhesion Promotion
Surface treatment technologies are commonly used to enhance the adhesion potential of base flexible packaging substrates for the application of performance adhesives, coatings and inks. The relationship between ribbon burner flame treatment technology and enhanced velocity (EV) port burner technology, and the degree of surface modification for adhesion promotion, is compared. Results showed that packages subjected to flame treatment prior to coating and printing performed significantly better, providing significant benefits. The subsequent measurement of dyne levels, peel adhesion and longevity tests following separate ribbon burner and drilled port flame surface treatments of various flexible packaging materials indicated definable differences between flame burner technologies and their effectiveness.
