What are the optimal storage conditions for long-lasting three proof thermal paper?

The optimal storage conditions for long-lasting three proof thermal paper are as follows:

1、 Environmental conditions

Temperature and Humidity

Temperature: The ideal ambient temperature is 23 ± 2 ℃. Avoid storing thermal paper in high temperature environments, as high temperatures can accelerate the decomposition of chemicals in the thermal coating, leading to fading of handwriting.

Humidity: The relative humidity should be maintained at 60%~70% or 65% ± 5%. Keep the storage environment dry and prevent the thermal paper from getting damp. Because moisture can decompose the chemical components of thermal paper, accelerating its fading process.

light

Avoid light: Avoid direct sunlight on thermal paper, as ultraviolet radiation can accelerate the decomposition of chemicals in the thermal coating, causing the handwriting to fade. Thermal paper should be stored in a cool, dark place.

2、 Packaging and storage methods

Sealed packaging

Seal and package thermal paper with moisture-proof paper, film, or plastic bags to reduce the erosion of air, moisture, and dust on the thermal paper. For printed thermal paper labels, it is recommended to stack them in layers and avoid being too heavy to prevent glue from sticking through.

Vertical stacking

For thermal paper packaged in rolls, it should be stacked vertically to prevent curling and deformation. Flat thermal paper should be stored flat, with a height of no more than 1 meter per board, and the goods should be at least 10 centimeters above the ground to prevent moisture and contamination.

3、 Other precautions

Avoid contact with chemicals

When storing and using thermal paper, contact with chemicals should be avoided as much as possible, as these chemicals may damage the surface coating of the thermal paper, resulting in poor printing performance or inability to print.

Regular inspection and cleaning

Develop the habit of regularly checking and cleaning printing equipment to maintain its cleanliness and normal operation. This helps ensure that thermal paper can print clear and beautiful printed materials normally and stably during the printing process.

In summary, the optimal storage conditions for long-lasting three proof thermal paper include suitable temperature and humidity, dark storage, sealed packaging, correct stacking methods, and avoiding contact with chemicals. Following these conditions can maximize the storage time of thermal paper and maintain its good printing effect.
