To avoid fading or aging of PET matte silver thermal paper during storage, the following measures can be taken:
1、 Environmental condition control
Temperature and humidity:
The ideal ambient temperature is 23 ± 2 ℃, and the relative humidity is 60%~70% or 65% ± 5%. Such environmental conditions can minimize the aging rate of thermal paper to the greatest extent possible.
Avoid storing thermal paper in environments with excessively high or low temperatures and humidity, as extreme conditions can accelerate the aging process of the paper.
Avoid light:
Thermal paper is highly sensitive to sunlight and ultraviolet radiation, and prolonged exposure to sunlight can cause the paper to turn yellow, fade, or even deteriorate.
Therefore, thermal paper should be stored in a cool and dark place, avoiding direct sunlight.
moisture-proof:
Keep the storage environment dry and prevent the thermal paper from getting damp. Moisture will decompose the chemical components of thermal paper, accelerating its fading process.
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.
2、 Storage method optimization
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.
Avoid pressure:
Thermal paper is relatively fragile and easily deformed by external forces. When saving, avoid placing heavy objects on the paper to avoid affecting the printing effect.
Classified storage:
Classify and store thermal paper according to usage frequency and paper size for easy management and retrieval.
3、 Special handling and protection
Plastic sealing:
If it is necessary to store documents or labels printed on thermal paper for a long time, plastic sealing can be considered for protection. However, it should be noted that the plastic sealing process may require heating, which may accelerate the aging of the thermal paper. Therefore, it is recommended to adopt cold mounting method and use non adhesive plastic film and cold mounting film for packaging.
Copy or scan:
Copying or scanning the content on thermal paper into an electronic document for storage is the most reliable method for long-term preservation of thermal paper information. This can avoid information loss caused by physical aging or fading of thermal paper.
4、 Regular inspection and maintenance
Regular inspection:
Regularly check the storage status of thermal paper, and replace it in a timely manner if there is yellowing, deformation, etc., to avoid affecting the printing quality.
Environmental monitoring:
Use monitoring devices such as thermometers and hygrometers to monitor the temperature and humidity conditions of the storage environment in real time, ensuring that the environmental conditions are always maintained within the ideal range.
In summary, by controlling storage environment conditions, optimizing storage methods, adopting special treatment and protection measures, and regularly inspecting and maintaining, PET matte silver thermal paper can effectively avoid fading or aging during storage.
