Product self-adhesive labels are a common product identification. With their stickiness, they can be directly attached to various flat, convex, and concave materials. They are widely used as identification objects in modern commercial activities. Unlike traditional paper labels, product self-adhesive labels are made of a material that is sticky, hard, waterproof, and oil-proof. They can be used for product identification, numbering, price, ingredients, and other information, and are also essential tools for product sales and management. They have become one of the important ways to identify modern products, providing merchants with better marketing methods and consumers with a richer shopping experience, while also providing consumers with better product protection.
