Abstract:
The polymeric composition comprising (A) a polyester resin and (B) micrometrical silica particles, preferably particles made of cristobalite or quartz, dispersed in the polyester resin preferably at concentration of at least 2wt%. The polyester resin preferably comprises a PET homo or copolymer. Packaging articles, especially biaxially stretched blow moulded containers, made with the said polymeric composition exhibit high opacity to UV and visible light radiations as well as improved barrier properties to O 2 and to water vapour, and improved thermal and mechanical properties.
