Because many synthetic resins suffer from photo degradation, the investigation of ways to inhibit or at least retard this type of degradation has been a major effort to the industry. Hindered amine light stabilizers (HALS) represent the most important development in light stabilization for many polymers, and in this presentation an overview of stabilization fundamentals will be provided together with some recent advances in this field. Performance data reported will show the benefit in using HALS as light stabilizing systems for plastic. The presentation will end with new directions into new additive technology that allows shelf-stable plastic packaging of oxygen sensitive ingredients and potential for extended shelf-life.
