  • Patent number: 10427319
    Abstract: Disclosed herein is a method of manufacturing a natural cork film, which includes forming a thin cork layer by slicing a prepared natural cork material, forming a fiber layer by attaching a fiber sheet to one surface of the cork layer formed in the forming a thin cork layer, pre-treating a lamination of the cork layer and the fiber layer formed in the forming a fiber layer, for preventing discoloration of the cork layer, and forming a resin layer by attaching a resin sheet to the fiber layer passing through the pre-treating a lamination of the cork layer and the fiber layer. Accordingly, it is possible to prevent the manufactured cork film from naturally discoloring due to light and to significantly reduce a phenomenon such as brittleness or wrinkling caused when the cork layer is decolorized alone.
