Abstract
A method of preparing a release layer of a release liner for a label laminate. A substantially continuous release layer with controlled thickness is formed on a liner substrate from a composition including at least a release agent and an inductive filler material. The release layer is heated to cure the release agent. The heating is at least partly based on electromagnetic induction heating of the inductive filler material. Also a release liner and a label laminate.
