What are the factors that affect the shelf life of small roll thermal label paper?

The factors that affect the storage life of small roll thermal label paper mainly include the following aspects:

1. Thermal paper material quality

Paper base and coating quality: The quality of thermal label paper directly affects its shelf life. High quality paper base and uniform thermal coating provide better color rendering and longer storage time. If the formulation of the thermal coating is not reasonable or the coating is not uniform, it will lead to a decline in print quality and accelerate the aging and fading process of the label paper.

Protective layer function: The protective layer of thermal label paper is also a key factor affecting the storage time. A good protective layer absorbs some of the light that causes the chemical reaction of the hot coating, slows down the deterioration of the printing paper, and protects the printer components from damage.

2. Printing conditions

Print temperature: A reasonable print temperature is essential for the preservation of heat-sensitive label paper. Too high a printing temperature will accelerate the chemical reaction of the heat-sensitive coating, resulting in local yellowing or blackening of the paper, which will affect the shelf life.

Printing device status: The status of the printing device also indirectly affects the preservation of the label paper. For example, if the print head is badly worn or improperly cleaned, it may lead to a decline in print quality, which in turn affects the preservation effect of the label paper.

3. Preservation of environmental conditions

Temperature and humidity: The temperature and humidity of the storage environment have a significant impact on the storage life of thermal label paper. In general, thermal label paper stored at a lower temperature and suitable humidity can maintain a longer storage time. If the ambient temperature is too high or the humidity is too large, it will accelerate the aging and fading process of the paper.

Light conditions: Direct sunlight or strong light will accelerate the chemical reaction of the heat-sensitive coating, causing the label paper to fade. Therefore, storing the label paper in a dark place can extend its shelf life.

Air contact: Prolonged contact with the air will accelerate the oxidation process on the surface of the thermal paper, thus affecting the preservation period. Therefore, it is recommended to store the label paper in a sealed bag or container to reduce contact with air.

4. Use and handling methods

Reduce physical contact: Frequent physical contact and friction will accelerate the wear and fading process of the surface of the thermal label paper. Therefore, the direct contact and friction of the label paper should be minimized during use.

Reasonable packaging and storage: For unused heat-sensitive label paper, it should be sealed with moisture-proof paper or film packaging to avoid moisture and pollution. At the same time, during the storage process, care should be taken to avoid stacking too high or being pressed by heavy objects to prevent deformation or damage to the paper.

In summary, the factors that affect the storage life of small roll thermal label paper mainly include the quality of thermal paper materials, printing conditions, storage environmental conditions, and use and treatment methods. In order to extend the storage period of thermal label paper, it is recommended to take corresponding measures from the above aspects.
