Small roll thermal label paper is not entirely suitable for long-term storage for the following reasons:
1、 Characteristics of thermal paper
The working principle of thermal paper is to heat the thermal coating on the surface of the paper through a thermal print head, triggering a chemical reaction that causes the coating to change color and display the desired text or image. However, this chemical reaction will gradually weaken over time, causing the printed text to gradually fade or even disappear.
2、 The impact of storage conditions
Temperature and humidity: The protective coating on thermal paper has high requirements for the storage environment. Generally speaking, thermal paper should be stored in a temperature range of 20-50 degrees Celsius and appropriate humidity. Excessive or insufficient temperature and humidity fluctuations can accelerate the chemical reaction of thermal sensitive coatings, leading to a decrease in printing performance.
Lighting: Long term exposure to light, especially high-intensity light, can accelerate the fading process of thermal paper. Therefore, avoiding direct sunlight and prolonged exposure to strong light is the key to storing thermal paper.
Air oxidation: The oxidation effect of air can also damage the protective coating of thermal paper, thereby affecting its printing effect and storage time.
3、 Retention period
The shelf life of thermal paper varies depending on its quality. Generally speaking, the storage time of ordinary thermal paper may only be a few months, while high-quality thermal paper can be stored for several years under suitable storage conditions. However, even the highest quality thermal paper cannot guarantee that the printing effect will remain the same after long-term storage.
4、 Alternative solutions
For information that requires long-term preservation, it is recommended to use other types of printing paper or label paper, such as carbon ribbon printing paper, laser printing paper, etc. These types of printing paper have longer shelf life and more stable printing effects.
In summary, small roll thermal label paper is not entirely suitable for long-term storage. If long-term storage of information is required, it is recommended to consider using other types of printing paper or label paper. Meanwhile, when storing thermal paper, attention should also be paid to controlling storage conditions to extend its shelf life and printing effect.
