Custom Security Labels: 3D Holograms + Tamper-Evident Tech

Tamper evident void labels are a specialized category of security labels engineered to leave a permanent, non-removable "VOID" message or pattern on the surface from which they are removed. OPOC Solution manufactures these labels using a proprietary layered structure: a top film layer (often polyester or polypropylene) printed with the brand logo and security features, a middle release layer that carries the void pattern, and a bottom adhesive layer that transfers the void to the substrate. This construction ensures that any attempted removal—whether slow, rapid, or aided by heat or solvents—results in the separation of the label layers, leaving the "VOID" message clearly visible on the product surface while the label top layer is removed. In the pharmaceutical industry, these labels are used on prescription bottles and clinical trial kits to guarantee that the medication integrity has not been compromised. A leading vaccine manufacturer adopted our void labels for secondary packaging; post-implementation audits showed that attempts to tamper with product packaging decreased by 90% in monitored distribution channels. The void pattern itself can be customized—beyond the standard "VOID," it can be tailored to display "OPENED," the company logo, or a custom message to reinforce brand presence. For applications like electronics warranty seals, the void feature is combined with a destructible substrate, making it impossible to transfer the label intact to another device. OPOC Solution’s engineering team can adjust adhesive strengths to suit different surfaces, from low-energy plastics to high-gloss metal, ensuring the void transfer mechanism functions as intended across a diverse range of packaging materials.
