Abstract: A method of making a multi-layer product or seal is described. An adhesive layer is applied to a surface of a first layer. A patch material is applied to a surface of the adhesive layer, using a coating or spraying process, to define one or more patches. At least the first layer is cut to define pre-formed lines of separation defining one or more first portions. Each first portion is associated with a respective one of the one or more patches.

Abstract: A cover sheet to be secured to the tray of a container is described. The cover sheet includes a first layer and a second layer. An adhesive layer is provided between the first and second layers. The first layer has a first cut line that extends across a corner of the cover sheet between a first edge and a second edge to define a tab portion of the first layer. The second layer has a second cut line that extends from the first edge to the second edge or a third edge to define a removable strip of the second layer. Removing the removable strip and the adhered tab portion exposes the adhesive layer on a securing portion of the first layer that can be used to secure the cover sheet to the tray.
