How to avoid discoloration of thermal label paper

To avoid discoloration of thermal label paper, the following measures can be taken:

Choose the appropriate thermal paper:

Choosing high-quality thermal paper usually results in better color stability and durability.

Choose the appropriate type of thermal paper based on usage needs, such as three proof paper thermal labels (waterproof, oil proof, scratch resistant), etc. These specially treated thermal papers have a longer storage time.

Optimize storage environment:

Store the thermal label paper in a cool and dry place, avoiding direct sunlight and high temperature environments.

Control the temperature and humidity of the storage environment to maintain a suitable range, such as 23 ± 2 ℃ and RH 65 ± 5% relative humidity.

Avoid improper operation:

During the printing and labeling process, avoid using excessive force or scratching the surface of the thermal paper to prevent damage to the coating.

Do not use transparent adhesive tape or other materials that may contain alkaline substances to cover the thermal label paper, in order to avoid chemical changes that may cause fading.

Reasonable packaging and storage:

Use moisture-proof paper or plastic film to package and seal the thermal label paper to prevent the intrusion of dust, moisture, and pollutants.

When storing, try to keep it flat and avoid folding or squeezing to reduce friction and damage between paper sheets.

Regular inspection and maintenance:

Regularly check the storage environment of thermal label paper to ensure that the insulation and humidity conditions meet the requirements.

For thermal label paper stored for a long time, regular sampling inspections can be conducted to ensure its color rendering performance and stability.

Follow the instructions for use:

Carefully read the instructions and shelf life information of the thermal label paper to ensure that it is used within its expiration date.

If the thermal paper has expired or shows obvious fading, it should be replaced with a new one in a timely manner.

In summary, to avoid discoloration of thermal label paper, it is necessary to choose suitable thermal paper, optimize storage environment, avoid improper operation, package and store reasonably, regularly inspect and maintain, and follow the instructions for use. The comprehensive application of these measures can effectively extend the storage time of thermal label paper and maintain its color stability.
