AI Technical Summary

Technical Problem

When using existing labels, the writing surface is easily affected by air and other factors, causing the content to discolor and affecting visibility.

Method used

The writing layer is protected by a protective layer and a bend layer. The combination of the protective layer, the bend, and the protective layer prevents oxidation and UV damage. At the same time, a third adhesive layer is used to adhere the protective layer when not in use, preventing damage or dirt to the protective layer.

Benefits of technology

It effectively prevents oxidation and discoloration of the writing layer, extends its service life, and keeps the protective layer clean and intact.
