The sealing strip of anti-counterfeiting label is damaged.

What you want to ask is what do you mean by the broken sealing strip of the anti-counterfeiting label? It is a label in the form of a seal, and now this seal is broken.

As a seal, the label has destructive anti-counterfeiting function. For example, each pack of cigarettes has a cigarette label. When smoking, the cigarette label must be torn off first (and must be torn off), so there is no problem that the cigarette label is reused.
