PROBLEM TO BE SOLVED: To provide an easy release paper sheet which excels in respect of sealing performance during transportation, excels in design performance and tampering prevention effect during display and has a thin layer thickness, and in which a printed layer is not ruptured when opened, printed information is easy to see, another information covered up during sealing can be printed to display and productivity and cost performance are excelled. SOLUTION: The present invention relates to a laminated film which is at least formed by laminating in turn a paper matrix layer, a non-polar resin layer, a polar resin film having an easy adhesion treatment surface on one side thereof and the non-polar resin layer, and the easy release paper sheet which is thermocompression-bonded with the non-polar resin layer on the upper layer of the laminated film with the paper matrix layer, wherein the thickness of the non-polar resin layer at the untreated surface side is made thinner than the easy adhesion treatment surface side, and a release surface is included only on one interface of the non-polar resin layer and the polar resin layer.
