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

The storage conditions for long-lasting three proof thermal paper mainly include the following aspects:

1、 Temperature and humidity

Temperature: Long term three proof thermal paper should be stored in a cool place to avoid high temperature environments. Generally speaking, the temperature of the storage environment should be kept at a low level, preferably not exceeding 30 degrees Celsius. If the temperature is too high, such as being exposed to sunlight and exceeding 30 degrees Celsius, thermal paper may only be stored for about ten days.

Humidity: Moisture resistance is the key to storing long-lasting three proof thermal paper. A humid environment can cause paper to mold or deform, and also affect the clarity of printed text. Therefore, it is necessary to ensure that the humidity of the storage environment is moderate and avoid excessive humidity.

2、 Lighting conditions

Avoid direct sunlight: Prolonged exposure to sunlight can accelerate chemical reactions on thermal paper, leading to fading of handwriting. Therefore, long-lasting three proof thermal paper should be stored in a place away from direct sunlight, such as a cool place or covered with shading materials.

3、 Environmental pollutants

Avoid contact with solvents, plasticizers, etc.: Certain chemicals such as solvents, plasticizers, etc. may have adverse effects on long-lasting three proof thermal paper, causing blurry handwriting or paper damage. Therefore, contact with these chemicals should be avoided during storage.

4、 Storage method

Encapsulation in a transparent plastic bag: Place the long-lasting three proof thermal paper into the transparent plastic bag and seal the opening to effectively prevent moisture and other pollutants from entering, thereby extending the storage time.

Avoid stacking and heavy pressure: During storage, it is advisable to avoid stacking the long-lasting three proof thermal paper too high or subjecting it to heavy pressure, in order to prevent paper deformation or damage.

In summary, in order to ensure the storage quality and printing effect of long-lasting three proof thermal paper, it should be stored in a cool, dry environment away from direct sunlight, and avoid contact with chemicals such as solvents and plasticizers. Meanwhile, appropriate storage methods such as packaging with transparent plastic bags can also effectively extend the storage time.
