How long is the shelf life of self-adhesive coated paper?

The shelf life of self-adhesive coated paper is affected by many factors, including storage conditions, use environment, formula and process of self-adhesive. Therefore, its shelf life does not have a fixed standard answer.

In general, under ideal storage conditions (such as temperature (23 ±2)℃ and relative humidity 65% ±5%), self-adhesive coated paper can be stored for a long time, and some glues can even reach 2 years. However, in actual use, because the storage environment may not be able to achieve such an ideal state, the shelf life of self-adhesive coated paper may be shortened.

In addition, the shelf life of self-adhesive coated paper is also related to its specific application environment. For example, in the outdoor environment, due to the erosion of natural factors such as sunlight and rain, the shelf life of self-adhesive coated paper may be relatively short. In the indoor environment, because the environment is relatively stable, the shelf life of self-adhesive coated paper may be relatively long.

In addition, it is worth noting that the shelf life of self-adhesive coated paper does not mean that after this time label will immediately fail, but means that in this time range, the performance and appearance of the label can remain relatively stable. After exceeding the shelf life, the adhesion and color brightness of the self-adhesive coated paper may gradually decline, but it does not mean that it can not be used immediately.

In summary, the shelf life of self-adhesive coated paper is a relative concept, depending on storage conditions, the use of the environment and the formula and process of self-adhesive and other factors. In practical applications, it is recommended to evaluate and test according to the specific situation to ensure that the self-adhesive coated paper can meet the needs of use. At the same time, attention should also be paid to regularly checking and replacing expired labels to ensure the accuracy and validity of information.
