How long is the shelf life of thermal label paper, can it be used after the shelf life?

The shelf life of thermal label paper is not a fixed time, it is affected by a variety of factors, including the quality of thermal paper, storage environment, packaging quality, material quality and so on. The following is a detailed analysis of the shelf life of thermal label paper and its use after the shelf life:

First,Shelf life range

1.In general:

The shelf life of the general thermal label paper is about two to three years. This mainly depends on the quality of the thermal paper and the coating formula.

If the coating formulation is not correct or the quality of the thermal paper is too poor, the shelf life may be shortened to about one month.

2.Long-acting thermal paper:

Thermal paper with long shelf life belongs to long-acting thermal paper. These thermal paper can be stored for more than 10 years in a normal storage environment (avoid high temperature and humidity, direct sunlight, avoid contact with solvents, plasticizers, etc.).

Second,Use after expiration date

1.Print effect affected:

The printing effect and quality of heat-sensitive label paper that exceeds the shelf life will be affected. Since the chemical components in the heat-sensitive coating may have begun to break down, the print may be faint or blurry.

2.Not recommended:

Although some thermal label paper that has exceeded its shelf life may not have significant changes in appearance, it is not recommended to continue using it in order to ensure the print quality and the durability of the label.

Third,how to extend the shelf life

1.Correct storage:

Store heat-sensitive labels in a cool and dry place, away from direct sunlight and high temperature and humidity.

The outer wrapping paper should be retained after use in order to repackage the heat-sensitive label paper, which helps to extend its service life.

2.Pay attention to the packaging quality:

Choose heat-sensitive label paper products with good packaging quality to avoid damage during storage and transportation.

In summary, the shelf life of thermal label paper varies due to a variety of factors, generally in about two to three years. Thermal label paper beyond the shelf life is not recommended to continue to use, because its printing effect and quality may be affected. In order to extend the shelf life, heat sensitive label paper should be stored correctly and pay attention to the packaging quality.
