What is the approximate shelf life of copperplate adhesive labels?

The shelf life of copperplate adhesive labels is influenced by various factors, including the material of the label, manufacturing process, storage conditions, and usage environment. The following is a detailed analysis of the shelf life of copperplate adhesive labels:

1、 Shelf life under normal circumstances

Copperplate paper adhesive labels: At room temperature (generally referring to an environment of 2025 ℃, relative humidity 45% 65%), the shelf life of copperplate paper adhesive labels is usually around 5 years. This shelf life is estimated based on the premise that the label is stored and used under suitable conditions.

2、 Factors affecting shelf life

Temperature and humidity: High temperature and humidity environments can accelerate the aging process of labels, leading to a decrease in their stickiness and even detachment. On the contrary, in low temperature and low humidity environments, the stickiness of labels may increase, but prolonged exposure to extreme temperatures may also lead to a decrease in label performance.

Light exposure: Prolonged exposure to strong light, especially ultraviolet radiation, can accelerate the fading and aging process of labels.

Chemical substances: Certain chemical substances, such as oils, solvents, etc., may have a negative impact on the stickiness of labels, leading to label detachment or reduced stickiness.

Storage conditions: Proper storage conditions are crucial for maintaining the shelf life of labels. Labels should be avoided from being exposed to high temperatures, high humidity, strong light, or chemical substances.

3、 Shelf life in special application scenarios

In some special application scenarios, such as outdoor environments, high temperature environments, or situations that require long-term storage, the shelf life of copperplate adhesive labels may be shortened. For example, in outdoor environments, the shelf life of labels may be shortened to 1 year or even shorter due to exposure to wind, sun, and rain.

4、 Suggestions for extending shelf life

Select high-quality label materials and adhesives to improve the durability and anti-aging ability of labels.

When storing and using labels, try to maintain appropriate temperature and humidity conditions.

Avoid exposing the label to strong light or chemical substances.

For labels that require long-term storage, you can choose label materials with longer shelf life or use special storage methods.

In summary, the shelf life of copperplate adhesive labels is usually around 5 years, but the specific shelf life is affected by various factors. When selecting and using labels, appropriate label materials and storage conditions should be chosen based on specific application scenarios and requirements to ensure the quality and stability of the labels.
