How resistant is copper label paper to chemicals?

The resistance of copper label paper to chemicals is relatively weak, which is as follows:

First, overview of chemical resistance

Coated paper labels are not resistant to chemicals due to their production process and material characteristics. Especially in high temperatures, high humidity or environments containing chemicals such as flux, melting agents and cleaners, the performance of coated paper labels may be affected.

Second, Specific resistance analysis

1.Temperature resistance:

Coated paper labels have limited temperature resistance, usually within a temperature range of 80 ° C or 150 ° C, depending on the material and production process of the label. In a high temperature environment, the coated paper label may appear deformed, faded or fall off.

2.Chemical resistance:

Coated paper labels are less resistant to chemicals such as flux, melting agents and cleaners. These chemicals can erode the surface of the label, causing the label information to become blurred, fall off, or become completely ineffective.

Third, application precautions

1.Use environment:

When choosing to use coated paper labels, it is necessary to fully consider its use environment. If there is high temperature, high humidity or a lot of chemicals in the environment, you may need to consider using other label materials with stronger chemical resistance, such as high temperature labels, synthetic paper labels, etc.

2.Protection measures:

In some specific cases, if coated paper labels must be used, additional protective measures can be considered to enhance their chemical resistance. For example, cover the surface of the label with a protective film or use a special coating to increase its chemical resistance.

Fourth,Summary

In summary, the resistance of copper label paper to chemicals is relatively weak, especially in high temperature, high humidity or environments containing chemicals. Therefore, the selection of label materials needs to be comprehensively considered according to the specific use environment and needs to ensure that the label can play a long-term stable role. If there are a lot of chemicals in the environment or need to be exposed to high temperature and high humidity conditions for a long time, it is recommended to choose a label material with stronger chemical resistance.
