Improvement of environmental stress cracking performance, load‐carrying capacity, and UV light barrier property of polyethylene terephthalate packaging material

This study deals with the improvement of light barrier properties and stress cracking strength of polyethylene terephthalate (PET) packaging materials by incorporating calcium metaborate (CaB2O4). CaB2O4 powders were synthesized by the sol–gel method. After the extrusion process produced PET/ CaB2O4...

Description
Summary:This study deals with the improvement of light barrier properties and stress cracking strength of polyethylene terephthalate (PET) packaging materials by incorporating calcium metaborate (CaB2O4). CaB2O4 powders were synthesized by the sol–gel method. After the extrusion process produced PET/ CaB2O4 granules, the preform and bottle production was carried out by injection molding and blow molding. Compared to pure PET, UV transmittance is reduced (~88%), and it is more effective at lower wavelengths (
