  • Transfer Foils Utilizing Plasma Treatment to Replace the Release Layer
    Publication number: 20140272440
    Abstract: A method providing for the replacement of the traditional release layer of transfer foils uses a plasma treatment to chemically modify the foil side surface of a PET substrate of the transfer foils. The chemically modified surface of the PET substrate provides the necessary low surface energy and release characteristics to allow for the controlled release of the foil from the PET carrier film. Accordingly, plasma treated transfer foils can be made without a release layer.
