What is sulphite paper?

Sulphite paper, also known as acid-free paper, is a type of paper that has been treated with sodium sulfite or another chemical to make it resistant to acid degradation. This paper is commonly used for documents, archival materials, artwork, and photographs, as it helps to prevent yellowing and fading.

Sulphite paper is thicker and more durable than regular paper, and it is often used in printing and publishing applications. It is also commonly used in school and office settings, as it is suitable for writing or drawing. This paper is available in a range of weights and colours.

Sulphite paper is considered to be a more environmentally-friendly option than regular paper, as it is made from wood pulp that has been treated with chemicals to remove impurities and strengthen the fibres. The use of sulphite paper helps to reduce the amount of waste generated by paper production, and also helps to reduce the amount of pollutants released into the environment.
