Pressure sensitive adhesion performances (for tape and label applications) often change during long-term storage after hot melt pressure sensitive adhesives (HMPSA) are coated on a specific face stock such as paper, film, non-woven, or cloth. Most formulators and users believe that the change of performance is primarily caused by the aging of adhesive during manufacturing, processing, and/or storage. Besides the aging effect, in fact, one of the major causes results from the mating of HMPSA and face stock that is used. Read Article >>
