Specialty paper is the kind of paper with special functions made by paper machine using different fibers. For instance, if synthetic fiber, synthetic paper pulp or mixed wood pulp and other raw materials are modified or processed with different materials, the paper can have different functions and applications in below areas including daily life, construction materials, electrical products, industrial filters, machinery industry, agriculture, information industry, optics, culture and art, biochemical cutting-edge technology, etc. As long as the paper is used for special purposes, all can be called special paper generally.

The term 'specialty paper' has only been around since the 1960s. It is also called specialty processing paper. Specialty paper was originated from the carbon-free copy paper developed by National Cash Register Co. in the US in 1945. Later, other kinds of specialty paper was launched constantly, which helped broaden people’s horizon and change people’s traditional view towards paper. Raw materials are no longer limited to plant fiber, and non-plant fiber such as inorganic fiber and synthetic fiber has also been used. In the structure, in addition to the fiber interleaving layer, the number of coating layers can be increased as well; in effect, it can be made based on the design according to people’s needs, which can hardly be imagined in the past. However, there are many difficulties in the development of specialty paper, such as large capital investment, high requirement on equipment, great technical difficulties, etc. In the meantime, the application for many kinds of specialty paper is still limited and the market demand is still low. In the short term, specialty paper is still not popular and a large market is waiting ahead for exploration.

At present, the production of specialty paper is still very low in China, which is far from enough to meet the growing needs domestically. Specialty paper has wide application, high performance and added value, but due to the inadequate support from the applied academic research facility to the domestic small and medium factories producing specialty paper domestically, the development of specialty paper in China will still meet some obstacles. As long as enterprises that focus on the production of specialty paper make appropriate production plans and make progress towards product transformation and technology development, it is believed that a good environment for survival and development for domestic specialty paper industry can be established.
