5×15mm Scratch-Off Security Sticker – Silver/Black Cover Labels, 1000-Piece

The SCR-5x15 is a roll of 5mm × 15mm scratch-off security stickers designed to conceal PINs, recharge codes, warranty numbers, and authenticity marks on cards and product labels until the end user scratches them off. Each sticker consists of a transparent adhesive film layer topped with a removable opaque scratch coating—typically silver or black—that can be scratched away with a fingernail or a small tool to reveal the information printed underneath. The sticker is supplied as a 1000-piece roll, making it suitable for production environments where cards or labels are processed in batches.

The scratch layer is engineered to meet two core requirements: it must rub off easily with light pressure, and it must remain fully opaque so that the hidden code cannot be read through the sticker even under strong backlighting. The transparent film base provides good adhesion to common card surfaces (PVC, paper, coated board), and the adhesive is formulated for permanent bonding once applied. Common background colors are silver and black, and custom printing on the scratch layer—such as zebra or leopard patterns—is possible in volume orders. The stickers are widely used on mobile phone recharge cards, lottery and scratch-win cards, warranty seals, authenticity labels, gift cards, and discount cards, where the integrity of the concealed code is critical.

The product is a passive adhesive label—it does not contain electronics, does not generate data, and requires no power. Its performance depends on correct application (clean, dry surface), controlled storage conditions, and the quality of the underlying print. The 5×15mm size is a compact format suited to short codes (typically up to 8–10 characters), and it is one of the most common stock sizes for recharge and lottery card covers. The roll format allows manual or semi-automatic dispensing, and the stickers can be applied by hand or with a label applicator.
