``UVA S-Pack'' is a new UV absorber additive designed to protect PET packaging content from the damaging effects of UV radiation. Compared to conventional UV absorbers that have been used for this purpose, this new product offers broader UV protection with less discoloration. The performance of this new UV absorber in content protection was demonstrated in exposure tests with vitamins and colorants. The product is also FDA-cleared for use in PET for food-contact applications. Due to this product's unique absorption and emission profile, it is expected to also offer suitable performance in polyester-based films and sheets.
