Pressure-sensitive labels are adhesive labels that stick to surfaces without the need for heat or water. They are made with a special adhesive that bonds when pressure is applied, making them easy to use for various applications, such as packaging and product labeling. These labels come in different materials, including paper and plastic, and can be printed with text, images, or barcodes. Commonly used in industries like food, pharmaceuticals, and retail, pressure-sensitive labels provide a convenient way to convey important information and branding on products.
