Method of manufacture of a vessel closing assembly for adhesion into a screw cap in which a liner laminate comprising a substrate layer and a layer of stiff film on at least one side of the substrate layer, having an attachment surface for attachment to the seal laminate, is attached to a seal laminate comprising induction heat sealable layers for sealing at one side to a container and comprises at least one stiff film layer and an attachment surface at the other side whereby the attachment surface of the seal laminate faces the side of the liner laminate formed by the stiff film, the joining involving the steps of: providing a release surface on one of the attachment surfaces; applying a pressure sensitive adhesive composition, from a liquid composition to one of the attachment surfaces and drying the composition to leave an adhesive coating; and contacting the attachment surfaces to adhere the liner laminate to the seal laminate. |
