How long does the storage time of colored thermal label paper last?

The storage time of colored thermal label paper is influenced by various factors, including the quality of the label paper, storage environment, and processing methods. The following is a detailed analysis of the storage time of colored thermal label paper:

1、 Overview of Storage Time

The storage time of colored thermal label paper is usually short because its imaging principle is to release heat energy through the print head, causing the thermal layer on the thermal paper to undergo a chemical reaction, thereby forming an image. This type of heat sensitive layer is relatively fragile and easily affected by environmental factors such as temperature, humidity, and light, resulting in the gradual fading or even disappearance of handwriting color.

2、 Factors affecting storage time

Label paper quality:

High quality color thermal label paper, with more reasonable thermal coating and protective layer formula, can provide better anti fading and anti-aging performance, thus extending the storage time.

Poor quality thermal paper may only be stored for a few months, while high-quality thermal paper can be stored for several years under appropriate storage conditions.

Storage environment:

Light exposure: Long term direct sunlight can accelerate the aging process of thermal label paper, leading to fading of handwriting. Therefore, it is advisable to avoid exposing label paper to direct sunlight.

Temperature and humidity: High temperature and humid environments can accelerate the decomposition of chemicals on thermal label paper, thereby shortening the storage time. It is recommended to store label paper in an environment with a moderate temperature of 20-50 degrees Celsius and relative humidity.

Handling method:

The correct packaging and storage methods can extend the shelf life of colored thermal label paper. For example, use moisture-proof paper or film packaging to seal the label paper and prevent it from being corroded by air, moisture, and dust.

Avoid placing heavy objects on the label paper to prevent deformation or damage.

3、 Specific storage time

Under appropriate storage conditions, the storage time of colored thermal label paper is usually 1-2 years, but the specific time depends on the combined effect of the above factors. If the quality of the label paper is poor or the storage environment is harsh, the storage time may be further shortened. On the contrary, if high-quality label paper is used and the correct storage method is adopted, the storage time may be extended to several years.

4、 Suggestions for extending storage time

Choose high-quality thermal label paper: When purchasing, pay attention to the shelf life and storage conditions of the label paper, and choose products with reliable quality.

Reasonable storage: Store label paper in a cool, dry, and dark environment, and avoid prolonged exposure to sunlight or humid conditions.

Proper packaging: Use moisture-proof paper or film packaging to seal the label paper and prevent it from being corroded by the external environment.

Regular inspection: Regularly inspect the stored label paper to promptly identify and address any potential issues.

In summary, the storage time of colored thermal label paper is influenced by various factors, but it can be extended by selecting high-quality products, storing them properly, and packaging them correctly.
