Heat-resistant paper or ordinary paper which is more fast

In terms of sun fastness, heat-resistant paper and ordinary paper each have their own characteristics, but in general, ordinary paper may show better sun fastness in a conventional use environment. Here's the breakdown:

First, the sun fastness of high temperature thermal paper

Basic features: High temperature resistant thermal paper mainly through the thermal coating to achieve the printing function, the chemical substances in the coating can remain stable at high temperatures, so as to ensure that the printing information is clear and readable. However, the coating's resistance to UV rays may be relatively weak.

Fast performance: Because the working principle of thermal paper is based on the chemical changes caused by thermal sensation, this change may gradually reverse or be affected by prolonged exposure to ultraviolet light, resulting in the fading of printed information. In particular, without special treatment of high temperature thermal paper, after exposure to strong sunlight, the printed content may quickly fade.

Application environment: Although high temperature resistant thermal paper can remain stable in high temperature environments, its sun resistance may not be the best choice in scenarios that require prolonged exposure to sunlight.

Second, the sun fastness of ordinary paper

Basic material: Ordinary paper is mainly made of lignin fibers and other additives, and does not contain heat-sensitive coatings, so its sun fastness depends mainly on the physical and chemical properties of the paper itself.

Fast performance: Compared with thermal paper, ordinary paper is more resistant to ultraviolet light in the normal use environment. While prolonged exposure to strong sunlight may also cause the paper to turn yellow or fade, this process is usually much slower than the fading of printed information on thermal paper.

Application environment: Plain paper is more suitable for documents and files that need to be stored for a long time and may be exposed to sunlight.

Third, comprehensive comparison

Sun fastness: under the same conditions, the sun fastness of ordinary paper is usually better than that of high temperature thermosensitive paper. This is because regular paper does not contain heat-sensitive coatings that are susceptible to ultraviolet light.

Application scenario: If the printed document needs to be stored outdoors or in an environment exposed to sunlight for a long time, it is recommended to choose ordinary paper or other materials with better sun resistance. If it needs to be used in a high temperature environment and the requirement for sun fastness is not high, then high temperature resistant thermal paper may be a viable option.

4. Precautions

In the selection of paper, in addition to considering the sun fastness, but also need to consider other factors, such as printing effect, cost, environmental protection and so on.

For documents that need to be stored for a long time, no matter what kind of paper is used, it is recommended to take appropriate preservation measures, such as storage in a dry environment away from light, to extend the storage period of the file.

To sum up, ordinary paper is usually better than high temperature thermal paper in terms of sun fastness, but it is also necessary to consider comprehensively when selecting paper according to specific needs and application scenarios.
