The present application relates to polyester compositions, processes to prepare molded articles from these polyester compositions, and containers fabricated from polyester clay composites for food and beverages. The processing methods employed in this invention enable containers to be formed which exhibit excellent clarity. Specifically, the present invention relates to a process comprising forming a parison from a composite composition comprising about 0.10 to about 25 weight % platelet particles dispersed in at least one polyester at a processing temperature which is at least 50~ above the Tg of said polyester; and molding said parison into a clear, thin walled article.
La présente invention concerne de nouvelles compositions de polyester, de nouveaux procédés d'obtention d'articles moulés à partir de ces nouvelles compositions de polyester, ainsi que de nouveaux récipients fabriqués à partir de composites polyester/argile, pour aliments et boissons. Les procédés de production mis en oeuvre selon l'invention permettent la formation de récipients d'une grande transparence. De façon spécifique, la présente invention concerne un procédé consistant à former une paraison à partir d'une composition composite contenant d'environ 0,01 à environ 25 % en poids de particules sous forme de plaquettes dispersées dans au moins un polyester, à une température de traitement qui est supérieure d'au moins 50· à la température de transition vitreuse (Tg) dudit polyester, et à mouler ladite paraison pour former un article transparent à paroi mince.
