New attempt to complete the recyclability criteria for print products.

Abstract

Research has been undertaken to develop an adhesive application database to improve the recyclability by evaluating the behaviour of adhesives during recovered paper treatment. Although the INGEDE Method 12 is seen as the most important evaluation test of stickies, INGEDE Method 13 and some new test methods, for example the DeltaTOC or pitch counter method, have been evaluated for practicability. The investigation covered catalogues, magazines, books and pressure sensitive adhesives (PSAs) and during analysis, the sticky potential of the complete product, together with the adhesive backing or side glue application and, if existing, each adhesive used for gluing inserts, were evaluated separately. Different types of adhesives were also considered and a proposal put forward for recycling-friendly adhesive applications. A scoring system for the stickie forming potential of adhesive applications compatible to the deinkability evaluation has been proposed. A comparison of test methods h as shown that the INGEDE Method 12 is the best suitable macrostickies method for the investigation of adhesive applications in print products, because it delivers information about the amount and size distribution of macrostickies. Detection and amount of microstickies generated during the pulping of print products were difficult to measure because the DeltaTOC and pitch counter measurement did not work. A suitable method for detecting the amount of microstickies generated during the disintegration of a print product appears to be not yet available.
