Self-adhesive labels are labels that have a layer of adhesive on the back, allowing them to stick to surfaces without the need for additional glue or tape. These labels can be made from various materials such as paper, plastic, or vinyl, and can be used for a variety of purposes, including product labeling, shipping and mailing labels, and identification labels.

Self-adhesive labels are useful because they offer several benefits over traditional labels. First, they are easy to apply, and can be quickly and securely attached to a surface without the need for additional adhesive or tools. This makes them ideal for high-volume labeling applications, where speed and efficiency are important.
