Thermal paper is widely used in shopping mall POS terminal system, hotel catering system, banking system, telecommunications system, medical system and other fields. The principle of making heat sensitive silver paper is to apply particle powder on plain paper. The ingredients are colorless dyes, phenols or other acidic substances, separated by thin films. Under heating conditions, the film is melted and the powder mixed with a color reaction. The coloured handwriting on the heat sensitive silver paper is unstable and easy to fade, resulting in the difficulty of identifying the contents of the files.
