Abstract
Abstract A document laminate includes laminating sheets with adhesive on facing sides to laminate a document between the sheets, and shielding sheets covering the document and received within the laminating sheets. When the adhesive is heat activated, the shielding sheets are selected to be not degraded by the activating heat. A document can therefore be removed from the laminate by cutting along a line at one edge of the shielding sheets, and removing the document, which is not adhered to the shielding sheets or the laminating sheets.
