The present invention relates to a sheet comprising polyester, the sheet comprising at least one area (a) wherein the area (a) comprises at least one groove having a depth of >50 % with regard to the thickness of the sheet in the area (a), wherein the sheet has a thickness of 200 - 1000 µm in the area (a). Such sheet provides the ability to snap along the grooves in a predictable manner, whilst providing sufficient rigidity to avoid undesired bending under the influence of its own weight. La présente invention concerne une feuille comprenant un polyester, la feuille comprenant au moins une zone (a), la zone (a) comportant au moins une rainure ayant une profondeur de > 50 % par rapport à l'épaisseur de la feuille dans la zone (a), la feuille ayant une épaisseur de 200 à 1 000 µm dans la zone (a). Ladite feuille est apte à s'encliqueter le long des rainures d'une manière prévisible, tout en présentant une rigidité suffisante afin d'éviter une flexion sous l'effet de son propre poids.
