Abstract There is disclosed a capping capsule for sealing attachment to the neck portion of a container such as a bottle. The capsule consists of a base wall portion in the form of a planar disc from which extends integral with the disc a heat shrinkable tubular side wall portion of substantially uniform thickness. The planar disc is thicker than the tubular side wall portion and the peripheral outline of the base wall is smaller than the inner peripheral outline of the side wall portion.
