Warranty labels stickers are essential security tools used by manufacturers and service providers to protect products and prevent tampering. These specialized stickers are designed to indicate whether a product has been opened, tampered with, or altered after sale. Often featuring “void” text, destructible materials, or tamper-evident patterns, warranty label stickers offer a clear visual cue when removed or damaged.

Transparent label sticker printing refers to the process of printing labels on clear film materials such as polypropylene (BOPP) or polyester (PET). These labels are see-through, allowing the product or container to remain partially or completely visible. They are often referred to as “no-label look” stickers because when applied, they appear to be directly printed on the container, giving it a seamless and professional finish.
