What are the storage conditions for BOPP thermal sensitive synthetic paper?

The storage conditions for BOPP thermal sensitive synthetic paper mainly include the following aspects:

1、 Environmental condition control

Temperature: The ideal storage environment temperature is 23 ± 2 ℃. Excessive temperature may accelerate the decomposition of chemicals in the thermosensitive coating, thereby affecting the color stability and printing effect of the paper. Long term exposure to high temperatures may cause fading of BOPP thermosensitive synthetic paper.

Humidity: The relative humidity should be maintained within the range of 60% to 70% or 65% ± 5%. Excessive humidity may cause the paper to become damp, and the moisture will decompose the chemical components that cause thermal paper to fade, thereby accelerating its fading process. Maintaining a dry storage environment is crucial for extending the shelf life of BOPP thermosensitive synthetic paper.

2、 Lighting and protection

Avoid light: BOPP thermosensitive synthetic paper should be kept away from direct sunlight, as ultraviolet radiation can accelerate the decomposition of chemicals in the thermosensitive coating, leading to fading of handwriting. Paper should be stored in a cool, dark place, or sealed with moisture-proof paper, film, or plastic bags to reduce exposure to ultraviolet radiation.

Dust prevention: The storage environment should be kept clean to avoid contamination from dust and impurities. Dust and impurities may affect the cleanliness and printing effect of the print head.

3、 Packaging and stacking

Sealed packaging: Using moisture-proof paper, film, or plastic bags to seal and package BOPP thermosensitive synthetic paper can effectively isolate air, moisture, and dust, further extending the storage time of the paper.

Stacking method: 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.

4、 Chemical contact

When storing and using BOPP thermosensitive synthetic paper, try to avoid contact with chemicals as much as possible. These chemicals may damage the surface coating of thermal paper, resulting in poor printing performance or inability to print.

In summary, in order to ensure the quality of BOPP thermal sensitive synthetic paper and extend its shelf life, it is necessary to strictly control the temperature, humidity, and lighting conditions of the storage environment, and adopt appropriate packaging and stacking methods. Meanwhile, avoiding contact with chemicals is also an important measure to protect the quality of paper.
