What are the storage requirements for colored thermal label paper?

Special attention should be paid to the storage conditions of colored thermal label paper to ensure its quality and printing effect. The following are specific requirements for the storage conditions of colored thermal label paper:

1、 Temperature and humidity control

Temperature: Color thermal label paper should be stored in an environment of 23 ± 2 ℃ to ensure the stability of the chemical substances in its thermal coating and avoid accelerating or slowing down chemical reactions caused by high or low temperatures, which may affect the printing effect.

Humidity: The relative humidity should be controlled between RH60% -70%. Excessive humidity may cause the thermosensitive coating to absorb water, thereby affecting its printing quality and shelf life; However, low humidity may cause the paper to become too dry, increasing friction and wear during printing.

2、 Lighting and Protection

Avoid direct sunlight: Prolonged exposure to strong light can accelerate the decomposition of chemicals in the thermal sensitive coating, leading to color fading and decreased printing effect. Therefore, it is necessary to ensure that the colored thermal label paper is stored in a cool place and avoid direct sunlight.

Moisture proof and sun protection: In addition to controlling humidity, moisture-proof measures should also be taken, such as using moisture-proof paper or film packaging to seal well, to prevent moisture from entering. Meanwhile, sun protection is also essential, which can be done using dark packaging materials or stored in a dark place.

3、 Stacking and storage methods

Layered stacking: The printed color thermal label paper should be stacked in layers to avoid excessive weight and adhesive penetration and adhesion. This helps maintain the flatness and printing effect of the label.

Vertical stacking and flat storage: For rolled colored thermal label paper, it should be stacked vertically to prevent deformation; For flat label paper, it should be stored flat to avoid bending or folding.

Height and ground clearance: The height of each label paper should not exceed 1 meter, and the goods should be at least 10 centimeters above the ground (with wooden boards) to maintain ventilation and prevent moisture.

4、 Packaging and Sealing

Outer packaging: Color thermal label paper should have an outer packaging, and it is recommended to use plastic film for sealed packaging. This helps to keep it dry and clean, preventing the intrusion of dust and dirt.

Re sealing: After each use, it is necessary to seal and package it again to ensure optimal storage conditions.

5、 Other precautions

Avoid contact with chemicals: During storage and use, colored thermal label paper should be avoided from coming into contact with chemicals as much as possible, as these chemicals may damage the thermal coating, resulting in poor printing performance or inability to print.

Regular inspection: The stored colored thermal label paper should be checked regularly to ensure that it has not been damaged or deteriorated. If any problems are found, they should be dealt with promptly and replaced with new label paper.

In summary, the storage conditions for colored thermal label paper include temperature and humidity control, lighting and protection, stacking and storage methods, packaging and sealing, and other precautions. Following these requirements can ensure the quality and printing effect of colored thermal label paper, and extend its service life.
