Abstract
An elongate strip, from which sealing members can be cut, has an elongate membrane and a first sheet. A first layer of adhesive is provided in the form of a series of elongate portions extending along the length of the strip and bonding the membrane and the first sheet together. An additional layer of adhesive is provided on the other side of the membrane. This enables sealing members to be cut from the elongate strip comprising a composite portion in which the membrane and first sheet are bonded together by the first layer of adhesive and a free portion in which the first sheet is separate from the membrane and forms a tab. In use, the additional layer of adhesive on the membrane is used to bond the sealing member to lip of a container, and the tab can then be used to remove the sealing member to open the container. The first layer of adhesive bonds the first sheet of the membrane together so strongly in the sealing member that they can be removed as a unit from such a container.
