The shelf life of thermal label paper is affected by many factors, including the quality of thermal paper, storage conditions, and environmental factors. The following is a detailed analysis of the shelf life of thermal label paper:
First, the shelf life range of thermal label paper
Ordinary thermal paper: the general storage time is 2 to 3 years, or even only a few months. If the coating of the thermal paper is not uniform or the chemical formulation is not reasonable, the storage time may be shorter.
Long-acting thermal paper: After special treatment of thermal paper, such as long-acting three thermal label paper, its shelf life can be as long as 8 years, 10 years, or even 15 years. The thermal coating of this type of paper is covered with a protective layer, which has better wear resistance and can keep the information legible under different environmental conditions.
Special purpose thermal paper: such as medical use of three special thermal paper, in the ideal condition of storage period requirements can be up to 2 years, usually imported thermal paper. And some special thermal papers even claim to have no expiration period, thanks to their unique gelatinous coating.
Second, the factors affecting the shelf life of thermal label paper
Thermal paper quality: The quality of thermal paper is a key factor in determining the length of its shelf life. High quality thermal paper, such as paper with uniform coating and reasonable chemical formulation, can provide a longer storage time. On the contrary, the shelf life of inferior thermal paper will be significantly shortened.
Storage conditions: The storage environment of thermal paper also has an important impact on its shelf life. Thermal paper should be stored in an environment that avoids direct sunlight, moisture, sun protection, high temperature and ultra-low temperature. Under suitable storage conditions, such as temperature control at 23±2 ° C and relative humidity RH65±5%, thermal paper can be stored for a longer time.
Environmental factors: Oxygen and moisture in the air may also oxidize the thermal paper and destroy its protective coating, thus affecting the preservation time. Therefore, it is recommended to seal the thermal paper with plastic film to avoid long-term contact with the air.
Third, how to extend the shelf life of thermal label paper
Choose high quality thermal paper: Ensure that the coating of thermal paper is uniform and the chemical formulation is reasonable to provide a longer storage time.
Reasonable storage: Store the heat-sensitive paper in an environment that avoids direct sunlight, moisture, sun protection, high temperature and ultra-low temperature. At the same time, the use of plastic film for sealing packaging, to avoid long-term contact with the air.
Pay attention to the use of environment: When using thermal paper, avoid exposing it to harsh environments such as high temperature, high humidity or strong light to extend its service life.
In summary, the shelf life of thermal label paper is not fixed, but is affected by a variety of factors. In order to extend its shelf life, high quality thermal paper should be selected and reasonably stored and used.
