The shelf life of transparent thermal sensitive label paper is influenced by various factors, including the quality of the label paper, storage conditions, and whether appropriate storage measures have been taken. The following is a detailed analysis of the shelf life of transparent thermal label paper:
1、 Quality factors
The quality of transparent thermal label paper directly affects its shelf life. Generally speaking, high-quality thermal paper has a more uniform protective coating and can effectively absorb the light that causes chemical reactions in the thermal coating, thereby slowing down the deterioration process of the printing paper. This type of thermal paper can be stored for 5 years or even longer at room temperature and away from direct sunlight. However, if the coating formula of thermal paper is unreasonable or of poor quality, its shelf life may be greatly shortened, sometimes only able to last for 1-3 months.
2、 Storage conditions
The storage conditions are equally crucial for the shelf life of transparent thermal label paper. The ideal storage temperature is 2050 ℃, and the relative humidity should be maintained between 60% and 70%. Excessive temperature or humidity can accelerate the decomposition of chemicals in thermal sensitive coatings, leading to fading of handwriting. At the same time, direct sunlight should be avoided as ultraviolet radiation can also accelerate the aging process of thermal paper. In addition, the oxidation function of air can also damage the protective coating of thermal paper, so long-term contact between label paper and air should be minimized as much as possible.
3、 Preservation measures
Taking appropriate storage measures can extend the shelf life of transparent thermal label paper. For example, using moisture-proof paper, film, or plastic bags to seal and package label paper to reduce the erosion of air, moisture, and dust. For printed labels, they should be stacked in layers and avoid being too heavy to prevent glue from sticking through. For transparent thermal label paper packaged in rolls, it should be stacked vertically to prevent curling and deformation. At the same time, the goods should be at a certain height above the ground to prevent the influence of moisture on the ground.
4、 Estimation of retention period
Taking into account the above factors, the shelf life of transparent thermal label paper can vary from several months to several years. High quality thermal paper can be stored for several years under ideal storage conditions and with appropriate preservation measures. However, if the quality of the label paper is poor or the storage conditions are poor, its shelf life may be greatly shortened.
5、 Precautions
Try to avoid prolonged exposure to high temperatures, high humidity, or direct sunlight.
Seal the packaging promptly after use to extend the shelf life.
For information that requires long-term preservation, alternative methods of backup or recording can be considered.
In summary, the shelf life of transparent thermal label paper is a relatively complex issue that is influenced by multiple factors. To ensure the shelf life and printing effect of label paper, it is recommended that users choose high-quality thermal paper when purchasing and take appropriate storage and preservation measures.
