Removability of adhesive applications The removal ability of adhesive applications is another product related quality aspect of paper products. Adhesive applications may form tacky particles, so-called stickies, in the paper recycling process. In graphic paper, the most visible components are glued spines of books, catalogues and magazines, glued inserts in magazines, labels of all kinds
