A lamination structure comprises a first layer bonded to a second layer. The first layer is bonded to the second layer by a destruct bond with a starch adhesive. The first layer may be a flat layer or a fluted layer and the second layer may be a flat or fluted layer. At least one surface of the first layer and/or the second layer, which is bonded to the other layer, is the surface of a thermoplastic film. The thermoplastic film is treated or coated in a manner sufficient to permit the surface or surfaces to form the above-mentioned destruct bond, using a starch adhesive. An example of a surface treatment is flame treatment. An example of a coating is an acrylic coating.
