Label Lock™ tamper proof dual-layer security labels are designed for environments where security, authenticity and visible evidence of tampering are essential. These advanced security seals provide reliable protection against unauthorized access, opening or manipulation and can be applied across a wide range of industries and high-security applications.

The dual-layer construction ensures that once the label is removed or tampered with, both the label itself and the protected surface clearly display a visible “OPENED” message. This provides immediate visual evidence of unauthorized access and helps prevent resealing attempts or unnoticed tampering.

The labels are suitable for both temporary and long-term sealing applications and are widely used by government institutions, transport companies, logistics providers, security organisations and multinational corporations. They are commonly applied to confidential and secure mail, valuable products, parcels, shipping boxes and transport consignments, customs and border control materials, examination and confidential document envelopes, election ballot boxes, voting systems, forensic evidence bags and envelopes, aviation containers, catering equipment, security packaging, transport seals, warehouses, restricted storage facilities, pharmaceutical and medical logistics, electronic equipment, technical devices and many other environments where protection against unauthorized access is critical.

Label Lock™ security labels not only protect assets but also provide a clear indication of unauthorized removal or interference. Once removed, both the label and the application surface permanently reveal an “OPENED” message, creating visible tamper evidence and significantly increasing protection against fraud, substitution and manipulation.

Dual Layer Label Lock™ labels are available in several standard sizes and each label is individually marked with a unique serial number to support identification, traceability and security control procedures. Labels can also be customised with company logos, warning texts, serial numbering systems, barcodes, QR codes and personalised security messages to meet specific operational, security or branding requirements.

These tamper evident labels provide a professional, reliable and highly effective security solution for organisations requiring visible proof of integrity, authenticity and protection throughout their operational processes.
