Abstract

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.
