Abstract
Method for obtaining a sheet intended to cover all kinds of documents, characterized in that it consists of a synthetic resin in the form of transparent cellulose sheet, composed of formaldehyde-urea-melamine, which (set of sheets and document) is subjected to a high pressure (100/120 kilos cmº and temperatures of 130/150º c.) between two perfectly shiny metal plates and dimensions a little bigger than the sheet that is intended to protect, so that there is a small border of plastic substances.
