The present invention relates to the use of a packaging material based on a thermoplastic polymer for packaging a dianhydrohexitol, the packaging material comprising at least one thermoplastic polymer layer containing at least 0.1% by weight of at least one antioxidant (layer (A)), said layer (A) either being directly in contact with the dianhydrohexitol or being separated from the latter by a thermoplastic polymer layer (layer (B)) having a thickness at most equal to 150 µm, and the thermoplastic polymer of the layer (A) and/or of the layer (B) being chosen independently from polyethylene, polypropylene, ethylene/polypropylene copolymers and blends of the latter. La présente invention concerne l'utilisation d'un matériau d'emballage à base de polymère thermoplastique pour emballer un dianhydrohexitol, le matériau d'emballage comprenant au moins une couche de polymère thermoplastique contenant au moins 0,1 % en poids, d'au moins un agent anti-oxydant (couche (A) ), ladite couche (A) étant soit directement en contact avec le dianhydrohexitol soit étant séparée de celui-ci par une couche en polymère thermoplastique (couche (B) ) ayant une épaisseur au plus égale à 150 µm, et le polymère thermoplastique de la couche (A) et/ou de la couche (B) étant choisi indépendamment parmi le polyéthylène, le polypropylène, les copolymères d'éthylène et de propylène, et les mélanges de ceux-ci.
