Foamed gaskets comprising at least one homogeneously branched ethylene polymer and at least one blowing agent are disclosed. The gaskets are particularly useful for sealing food and liquid containers and do not contribute to taste and/or odor of the packaged product, which is especially useful in food-stuff applications.
L'invention concerne des joints d'étanchéité moussés comprenant au moins un polymère éthylénique à branchement homogène et au moins un agent gonflant pour mousse. Ces joints sont particulièrement utiles pour fermer hermétiquement des récipients d'aliments et de liquides, et ils ne modifient pas le goût et/ou l'odeur du produit emballé, ce qui est particulièrement utile dans les applications alimentaires.
