How to store PET thermosensitive silver paper correctly?

Proper storage of PET thermosensitive silver paper requires attention to the following aspects to ensure its quality and extend its service life:

1、 Environmental condition control

Temperature: The temperature of the storage environment should be controlled within an appropriate range, and it is generally recommended to store at room temperature to avoid excessively high or low temperatures. The specific temperature can be controlled at around 23 ± 2 ℃ or 25 ℃ to ensure that the paper will not deform or age due to temperature changes.

Humidity: Humidity is one of the key factors affecting the storage quality of PET thermosensitive silver paper. The relative humidity of the storage environment should be maintained at 60%~70% or 65% ± 5% to avoid excessive humidity or dryness. Excessive humidity may cause paper to absorb moisture and deform, while low humidity may make paper brittle.

2、 Avoid light and moisture

Avoid light: PET thermosensitive silver paper is sensitive to light, and prolonged exposure to sunlight can cause the paper to fade and deteriorate. Therefore, it should be stored in a cool and dark place, avoiding direct sunlight.

Moisture proof: Keep the storage environment dry and prevent paper from getting damp. Moisture resistant paper, film, or plastic bags can be used to seal and package PET thermosensitive silver paper to reduce the erosion of air and moisture on the paper.

3、 Prevent compression and deformation

Avoid pressure: PET thermosensitive silver paper is relatively fragile and easily deformed by external forces. When storing, it is advisable to avoid placing heavy objects on paper to prevent deformation and affect the effectiveness of use.

Vertical stacking: For PET thermosensitive silver paper packaged in rolls, it should be stacked vertically to prevent curling and deformation. Flat paper should be stored flat to avoid stacking too high and causing pressure on the bottom paper.

4、 Classification storage and management

Classified storage: Classify and store paper according to its specifications, uses, etc. for easy management and retrieval. At the same time, it can also avoid confusion between paper of different specifications and uses.

Regular inspection: Regularly inspect the stored PET thermosensitive silver paper. If there is any deformation or fading, it should be replaced or processed in a timely manner to avoid affecting the use effect.

5、 Precautions

Avoid contact with chemicals: PET thermosensitive silver paper is prone to react with chemicals, so it should be stored away from contact with acids, bases, solvents, and other chemicals to prevent a decrease in paper quality.

Use specialized storage devices: If possible, specialized storage devices or boxes can be used to store PET thermosensitive silver paper to ensure stability and controllability of the storage environment.

In summary, the correct storage of PET thermosensitive silver paper requires controlling environmental conditions, avoiding light and moisture, preventing deformation under pressure, classified storage and management, and paying attention to avoiding contact with chemicals. These measures will help extend the service life of PET thermosensitive silver paper and maintain its good printing effect.
