Thermal paper is a special paper that uses thermal materials for printing, mainly used in printers, cash registers, vending machines and other equipment. Its structure is mainly divided into two layers: the surface layer is the photosensitive layer, the inner layer is the substrate layer. Through the heating head of the printer to heat the sensitive layer, you can print text, pictures and other information on the paper.
Due to the structure and use of thermal paper, it is very different from general paper, with the following characteristics:
1. The surface of the thermal paper shows the characteristics of smooth and bright white, which is difficult to be written and printed again.
2. Thermal paper will produce a chemical reaction after heating, and the surface material will change, which is difficult to recycle.
3. Thermal paper contains more chemicals and plastic components and cannot be recycled with other papers. If recycled together with ordinary paper, it will affect the quality of cellulose and is difficult to be made into paper again.

Taking into account the particularity of thermal paper, the thermal paper that has been used should be properly handled. Some possible practices include:
1. Garbage classification: Put the used thermal paper into the harmful trash can and dispose of it separately from other garbage. This can reduce the pollution to the environment and protect the ecological environment.
2. Biodegradable: Many manufacturers have begun to develop biodegradable thermal paper materials that can be reduced to organic matter in the soil after treatment. Although this method is not very popular, it may become an option for recycling in the future.
3. Reduce the use: in the use of thermal paper should minimize the amount, do not waste. At the same time, other more environmentally friendly printing methods can also be used, such as laser printing, ink printing and so on.
The recyclability of thermal paper is not high, and the environmental pollution caused by it needs to be restricted and controlled in use and treatment. It is hoped that when using thermal paper, people should not only pay attention to its convenience and practicality, but also pay attention to its environmental protection.
