This term refers to printing the logo of another company’s registered trademark on the product packaging.

The sleeve label is a kind of anti-counterfeiting label, which is mainly used to prevent counterfeiting and prevent diversified goods. Corresponding to the product and packaging box one-to-one, it is "secondary packaging" or "primary assembly" in which other companies' registered trademarks are affixed to the product packaging, commonly known as labeling.

Sleeve labels, also called sub-labels, refer to one-to-one anti-counterfeiting labels affixed to products and packaging boxes. Tags are divided into two parts, namely child tags and parent tags. The parent and child tags correspond one to one and are each other's password.
