Zusammenfassung:	A process for making recyclable, reclosable lids with living hinges made from copolyester compositions which comprise residues of terephthalic acid, 1,4-cyclohexanedimethanol (CHDM), and ethylene glycol (EG) residues, in certain compositional ranges that have low haze and are recyclable in a PET stream. L'invention concerne un procédé de fabrication de couvercles recyclables et refermables dotés de charnières vivantes, fabriqués à partir de compositions de copolyester qui comprennent des résidus d'acide téréphtalique, de 1,4-cyclohexanediméthanol (CHDM), et des résidus d'éthylène glycol (EG), selon certaines proportions de composition qui leur confèrent un faible trouble et les rendent recyclables dans un flux de PET.
