FYI - I'm forwarding this for Steve Severtson and AF&PA...if you need copies of the attachments he mentions let me know and I will forward the files to you directly. Christine McCoy I have attached several publications on benign hot-melt PSAs, which resulted from a research partnership between my group at the University of Minnesota, H.B. Fuller Company (St. Paul, MN) and Boise Cascade Corp. (International Falls, MN). The project was funded by the U.S. DOE through the AF&PA Agenda 2020 Program. As a result of this work, we believe H.B. Fuller Company can now provide benign hot-melt PSAs to meet any customer specification without sacrificing performance, and these adhesives do not cost any more than their conventional glues. Currently, Avery Dennison offers a line of PS labels (EnviroSensitive?sect;) that are produced with Fuller's benign PSAs and a second major producer plans to release a new line of PS labels produced with Fuller's benign adhesives later this month. It is important to point out that initially our efforts were focused on PSA film, but we quickly realized that the label paper or facestock can have a significant influence on PSA fragmentation. Our findings demonstrate that for most PSAs, the adhesive alone cannot be certified as benign. The entire laminate must be considered. For both of the PS label product lines mentioned above, we worked with H.B. Fuller and the label converters to identify the correct facestock for the selected adhesive properties. Currently, we are working with a new research partner, Franklin International (Columbus, OH), on identifying the properties controlling the fragmentation of water-based PSAs during recycling operations. Water-based systems are much more complex than the hot-melts, but it is important to study these materials given that they compose a larger portion of the PSA label market (about 80% vs. 15% for the hot-melts). Our ultimate objective is to make it easy for label producers to supply the market with products that do not interfere with the recycling process, so that high removal efficiency during recycling operations simply becomes an accepted product specification for PS labels being developed for paper applications. If you have questions regarding the attached articles or our research efforts, please call or email me.
