Can colored copperplate label paper resist UV aging?

Colored copperplate label paper may not be completely resistant to UV aging. Although some outdoor sun resistant labels or specially treated colored copperplate paper may have some UV resistance, ordinary colored copperplate paper may experience fading, aging, and other phenomena when exposed to strong UV radiation for a long time.

Ultraviolet radiation has high energy and contains UV-B and UV-C components, which have strong oxidative properties. When ultraviolet rays are irradiated onto the surface of paper, they can damage organic molecules such as cellulose, leading to paper aging. For colored copperplate paper, the ink and coating on its surface may also be affected by ultraviolet radiation, resulting in fading or deterioration.

Therefore, if labels or printed materials need to be used outdoors for a long time, it is recommended to choose materials with UV resistance, such as copperplate paper printed with sun resistant ink or paper with special UV protection coatings. These materials can resist ultraviolet radiation to a certain extent, extending the service life of printed materials.

Meanwhile, when using colored copperplate label paper, attention should also be paid to avoiding prolonged direct exposure to sunlight to reduce the impact of ultraviolet rays on the paper. If long-term storage is required, it is recommended to store it in a cool, dry, and ventilated environment to extend its service life.
