Abstract
A method for providing an inductive sealing bar, comprises providing a conductive coil having at least one heating zone, embedding the coil in a supportive body such that the supportive body covers the entire coil along at least some part of the length of the at least one heating zone; and providing a sealing surface of the sealing bar by planarizing the coil and the supportive body such that the coil is exposed along the entire length of said at least one heating zone. The invention also relates to a sealing bar manufactured according to the method.
