Background Art

Self-adhesive labels, also known as self-adhesive labels and pressure-sensitive labels, are products with adhesive backing and covered with paper or silicone oil paper. The back of this label is coated with adhesive and the bottom is covered with a layer of silicone paper. This design allows users to easily stick the label on various products or surfaces by simply peeling off the backing paper. Due to its convenient and fast characteristics, self-adhesive labels are widely used in various industries and fields, including product packaging, logistics, inventory management, asset management, etc. In addition, self-adhesive labels have a wide range of customization possibilities, and different materials, sizes, shapes and printing designs can be selected according to different application requirements.
