What is the shelf life of long-lasting three proof thermal paper?

The shelf life of long-lasting three proof thermal paper is affected by various factors, including paper quality, production process, storage conditions, and environmental factors. Generally speaking, the shelf life of long-lasting three proof thermal paper can be several years or even longer.

Specifically, if the long-lasting three proof thermal paper is made of high-quality materials and production processes, and stored in a suitable environment (such as a cool, dark, dry, ventilated place, avoiding high temperature, high humidity, direct sunlight, and contact with solvents, plasticizers, and other chemicals), its shelf life can reach more than 10 years or even longer. Some high-quality long-lasting three proof thermal paper, after special treatment and testing, claims to be able to be stored for 8, 10, or even 32 years.

However, it should be noted that the color reaction of thermal paper is reversible, meaning that over time, the handwriting on the thermal paper may gradually fade. Therefore, although long-lasting three proof thermal paper has a long shelf life, it still needs to be evaluated and selected based on specific circumstances in practical applications.

In addition, in order to extend the shelf life of long-lasting three proof thermal paper, it is recommended to take the following measures:

Proper storage: Store thermal paper in a cool, dark, dry, and ventilated place, avoiding high temperature, high humidity, and direct sunlight.

Sealed packaging: Use moisture-proof paper, film, or plastic bags to seal and package thermal paper to reduce the erosion of air, moisture, and dust.

Avoid chemical contact: During storage and use, avoid contact between thermal paper and chemicals such as solvents and plasticizers to prevent damage to the surface coating of the paper.

In summary, the shelf life of long-lasting three proof thermal paper varies due to various factors, but generally it can reach several years or even longer. In practical applications, evaluation and selection should be based on specific circumstances, and appropriate measures should be taken to extend its shelf life.
