At present, thermal paper is used as the communication carrier of text and graphics on the fax machine, that is, as the fax paper, and as the recording material in the medical and metering systems, such as electrocardiogram drawings, thermal instrument recording paper and other printing paper used in the Internet terminal.  In terms of commercial activities, it is used to make trademarks, signage and so on, among which the amount of fax paper occupies the largest proportion. 

As early as the 1930s, people developed thermal recording technology.  Thermal paper is a kind of processing paper, its production principle is in the ordinary paper base coated with particle powder, composition is colorless dye phenols or other acidic substances, separated by the film, under the condition of heat, the film melt, the powder mixed chromogenic reaction.  Thermosensitive recording system is divided into two categories: one is the physical thermal recording paper which uses heat to make the colored pigment into physical color to achieve the recording effect, the other is the use of heat under the action of chemical reaction to achieve the purpose of color chemical thermal recording paper.  Thermal paper which uses chemical method to produce color is dominant. 

How about the development of thermal paper market? 

At present, thermal paper in the fax machine as a text and graphics communication carrier, that is, as fax paper.  Used as recording materials in medical and metering systems, such as electrocardiogram drawings, thermal instrument recording paper, etc.  Printing paper for Internet terminals;  In terms of commercial activities, it is used to make trademarks, signage and so on, among which the amount of fax paper occupies the largest proportion. 

Melt transparent thermal recording paper 

The use of physical methods of color thermal recording paper melt transparent type, melt transfer printing type, thermal rise and supercooling method.  Melt transparent type is representative. 

Melt transparent thermal recording paper, using the principle of melt transparency, that is, on the black base paper, coated with a layer of opaque wax as the surface layer, the thermal hair effect, so that the opaque waxy material melt transparency, the color of the bottom of the base paper is revealed and constitute the image.  This kind of thermal paper, widely used in medical electrocardiogram, electroencephalogram or industrial general meter line recording. 

As the printing cost of ordinary printer increases gradually, thermal printer gradually replaces the market of ordinary printer, the market of thermal printing paper is further opened, and its share in the printing paper market will be more and more large, which is a new trend in the development of printing paper market. 

Thermal paper products in China accounted for a large proportion of the middle and low grade and part of the supply has exceeded the demand situation.  Analysis of the development trend of thermal paper industry shows that China's high-end thermal paper market is in its initial stage, and the competition of thermal paper is not sufficient.  Foreign manufacturers occupy most of the market share, and some domestic enterprises have increased relevant investment to seize the market share.  The development prospect of high-end thermal paper market is broad. 

China's thermal paper industry presents industrial cluster effect in the eastern region, with more enterprises concentrated in Guangdong, Jiangsu, Zhejiang and other places.  The developed regional economy and convenient trade conditions give rise to the thermal paper industry cluster in this region, and the effect of scale economy further promotes the growth of regional industry share. 

At present, China's thermal paper industry presents industrial cluster effect in the eastern region, and more enterprises are concentrated in Guangdong, Jiangsu, Zhejiang and other places.  According to relevant data, in 2020, China's thermal paper market size ranks first in Guangdong province, with a market size of about 419 million yuan, followed by Zhejiang province, with a market size of 388 million yuan.  In addition, Jiangsu, Shanghai, Shandong, Sichuan and other provinces are relatively considerable market scale. 

On the basis of summarizing the development course of China's industry and combining various factors in the new era, the research report of thermosensitive paper industry gives a careful and prudent prediction and demonstration to the development trend of the industry.
