What factors affect the storage time of PET matte silver thermal paper?

The storage time of PET matte silver thermal paper is affected by various factors, mainly including the following aspects:

1、 Thermal paper quality

Thermal coating formula: The coating formula of thermal paper plays a critical role in its storage time. A high-quality coating formula can slow down the aging rate of thermal sensitive coatings, thereby extending their storage time. On the contrary, thermal paper with an unreasonable coating formula may significantly shorten its storage time.

Protective coating: The quality and uniformity of the protective coating can also affect the storage time. A good protective coating can absorb some of the light that causes chemical reactions in the thermosensitive coating, slowing down the deterioration of the thermosensitive paper. If the protective coating is uneven or of poor quality, it may cause thermal paper to age faster.

2、 Storage conditions

Temperature and humidity: The ideal storage environment for PET matte silver thermal paper is crucial for its shelf life. Typically, a suitable temperature range is 2050 degrees Celsius (also known as 23 ± 2 ℃), with a relative humidity of 60% 70% or 65% ± 5%. Under such conditions, the aging rate of thermal paper can be minimized to the greatest extent possible. Excessive or insufficient temperature and humidity can accelerate the aging of thermal paper and shorten its storage time.

Lighting conditions: Long term exposure to light, especially direct sunlight, can accelerate the decomposition of chemicals in thermal paper, leading to fading of handwriting. Therefore, when storing, avoid direct sunlight and choose a cool, dark place to store.

Moisture prevention and sealing: Maintaining a dry storage environment is also key to extending storage time. Moisture will decompose the chemical components of thermal paper, accelerating its fading process. Therefore, it is recommended to use moisture-proof paper, film, or plastic bags to seal and package thermal paper, in order to reduce the erosion of air, moisture, and dust on thermal paper.

3、 Usage conditions

Print quality: During the printing process, if there are serious issues such as pigment accumulation and ink loss, it may affect the printing effect and storage time of thermal paper. Therefore, good printing quality should be ensured during use.

Contact with chemical substances: Thermal paper should avoid contact with chemicals as much as possible during storage and use. These chemicals may damage the surface coating of thermal paper, resulting in poor printing performance or inability to print, thereby affecting storage time.

In summary, the storage time of PET matte silver thermal paper is influenced by various factors such as the quality of the thermal paper, storage conditions, and usage conditions. In order to extend the storage time, high-quality thermal paper should be selected, storage conditions should be optimized, printing quality should be ensured, and contact with chemicals should be avoided.
