Webb17 nov. 2024 · Although the adhesive typically makes up just 2% of an end-use package, optimal adhesion is necessary for high-performance packaging applications. Since nearly half of an adhesive consists of a tackifier, adhesive suppliers can maximize their renewable content by incorporating a bio-based tackifier rather than a chemically derived alternative.
