Abstract
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.
