How long is the service life of bright PET label paper?

The service life of bright PET label paper is affected by many factors, including the quality of the label paper, storage conditions, use environment and specific application scenarios. Therefore, it is impossible to give an absolutely accurate service life. However, its service life can be roughly estimated based on general experience and reference information.

Service life in official environments

Under the official recommended environmental conditions, that is, the ambient temperature is 23±2 ° C and the ambient humidity is 50±5%, the adhesive validity period of the self-adhesive label (including PET material) can usually be stored for 1 year. However, this mainly refers to the expiration date of the adhesive, not the service life of the entire label paper.

Service life in real life

In real life, self-adhesive labels, including bright-white PET labels, can usually be stored longer. Large units of self-adhesive can be stored for more than 2 years under proper storage. If sealed storage is used, it can even be used after 5 years, although this may have some impact on the performance of the label, especially if the application requirements are not particularly harsh.

Factors affecting service life

1.Storage conditions: The temperature and humidity of the storage environment have an important impact on the service life of the label. Avoid high temperature, humidity, direct sunlight, and poor ventilation to extend the service life of the label.

2.Label paper quality: The quality of the label paper itself also affects its service life. High quality bright white PET label paper usually has better durability and stability.

3.Use environment: The use environment of the label paper is also a key factor in determining its service life. In harsh environments, such as high temperature, humidity, chemical corrosion, etc., the service life of the label paper may be shortened.

4.Application mode: The application mode of the label paper, such as the cleanliness of the paste surface and the paste pressure, will also affect its service life.

Sum up

In summary, the service life of bright white PET label paper will be affected by a variety of factors, and a specific time range cannot be given. But in general, in the case of proper storage and use, its service life can reach more than 2 years, or even longer. To prolong the service life of labels, it is recommended to pay attention to storage conditions, select high-quality labels, and use them in a suitable environment.
