What are the requirements for the performance of PET thermosensitive matte silver paper under storage conditions?

The storage conditions have a significant impact on the performance of PET thermosensitive matte silver paper. The following are specific requirements:

1、 Temperature and humidity control

Temperature: PET thermosensitive matte silver paper should be stored in a relatively stable temperature environment, with an ideal storage temperature of 23 ± 2 ℃. Avoid exposing it to temperatures that are too high or too low, as this may cause paper deformation, damaged printing results, or reduced label adhesion.

Humidity: Humidity is one of the key factors affecting the quality of PET thermosensitive matte silver paper. To ensure stable paper performance, the relative humidity should be controlled within the range of 60%~70% or 65% ± 5%. Excessive humidity may cause paper to absorb water and deform, while low humidity may make paper dry and fragile.

2、 Lighting conditions

Avoid light storage: PET thermosensitive matte silver paper should be stored in a cool, dark place. Long term direct sunlight or strong light exposure can accelerate the decomposition of chemical substances in paper, leading to fading printing effects or reduced label stickiness.

3、 Moisture and dust prevention

Moisture prevention: Maintaining a dry storage environment is crucial. Moisture will decompose the chemical components of thermal paper, accelerating its fading process. Therefore, moisture-proof paper, film, or plastic bags should be used to seal and package PET thermosensitive matte silver paper to reduce the erosion of air and moisture on the paper.

Dustproof: Dust and impurities may affect the printing effect and adhesion of PET thermal matte silver paper. Therefore, the environment should be kept clean during storage and the storage area should be regularly cleaned.

4、 Avoid contact with chemicals

PET thermosensitive matte silver paper should avoid contact with chemicals as much as possible during storage. These chemicals may damage the surface coating of the paper, resulting in poor printing performance or inability to print.

5、 Stacking and storage methods

Stacking method: For PET thermosensitive matte silver paper packaged in rolls, it should be stacked vertically to prevent curling and deformation. Flat thermal paper should be stored flat and the height of each board should not be too high to prevent deformation under pressure.

Storage location: The goods should be kept at a certain distance from the ground (such as more than 10 centimeters) to prevent moisture and contamination. Meanwhile, it is advisable to avoid storing PET thermosensitive matte silver paper in poorly ventilated or damp corners.

In summary, to ensure the performance of PET thermosensitive matte silver paper is not affected, storage conditions should meet requirements such as temperature and humidity control, light avoidance storage, moisture and dust prevention, avoidance of chemical contact, and reasonable stacking and storage methods.
