How long does the "long-lasting" of long-lasting thermal paper refer to?

The "long-lasting" of long-lasting three proof thermal paper specifically refers to the longevity of its storage time. The storage time of long-lasting three proof thermal paper may vary depending on different manufacturing processes and quality controls.

Generally speaking, three proof thermal paper made from high-quality domestic paper special fabrics has strong scratch resistance while being waterproof, oil resistant, and alcohol resistant, and can be stored for about 2 years. However, some higher quality long-lasting three proof thermal paper can achieve longer shelf life through special production processes and coating technologies. For example, some tested long-lasting three proof thermal paper can even be stored for 8, 10, or even 15 years. These papers not only have excellent heat resistance, water resistance, and oil resistance, but also exhibit clear and long-lasting printing effects during the printing process.

In addition, the storage time of long-lasting three proof thermal paper is also affected by the storage environment. In a normal storage environment (such as avoiding high temperature and humidity, direct sunlight, avoiding contact with solvents, plasticizers, etc.), the storage time of paper can be better guaranteed. If the storage environment is harsh, such as high temperature, humidity, or exposure to sunlight, the storage time of paper may be shortened.

Therefore, the "longevity" of long-lasting three proof thermal paper is not a fixed time, but is determined based on various factors such as paper quality, manufacturing process, and storage environment. When choosing long-lasting three proof thermal paper, it is recommended to choose the appropriate product based on specific application scenarios and needs, and consult suppliers or manufacturers for more accurate storage time information.
