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.
