The storage conditions for three proof thermal paper mainly include the following points:
1.Temperature: It should be stored in an environment with a temperature not exceeding 30 ℃. High temperatures may cause the handwriting on thermal paper to fade or become blurry, so it is crucial to choose a cool and shady place for storage.
2.Humidity: The relative humidity should be kept below 75% RH. Excessive humidity may cause thermal paper to become damp, thereby affecting its waterproof performance and usability.
3.Lighting: Avoid direct sunlight. Long term exposure to sunlight may accelerate chemical reactions on thermal paper, leading to rapid fading of handwriting. Therefore, when storing, one should choose a dark environment or use opaque packaging materials for packaging.
4.Sealing: To ensure that thermal paper is not affected by external air, dust, and other pollutants, it should be stored in a sealed manner. Transparent plastic bags or specialized sealed boxes can be used to store thermal paper and ensure that the seal is tightly closed.
5.Avoid contact with chemical substances: During storage, the three proof thermal paper should avoid direct contact with solvents, plasticizers, oil, water, sweat stains, and other chemical substances to prevent damage to its waterproof, oil resistant, and alcohol resistant properties.
In summary, in order to maintain the optimal performance of the three proof thermal paper and extend its service life, temperature, humidity, and lighting conditions should be strictly controlled during storage, and its sealing and avoidance of direct contact with chemical substances should be ensured. These measures will help ensure that thermal paper can maintain good printing quality and readability when needed.
