Label Lock High Residue security labels provide maximum protection against tampering and unauthorized access. When removed, the label immediately displays the message “OPENED,” while leaving behind a permanent residue layer on the surface. This tamper warning remains visible indefinitely, ensuring that the label cannot be reused. Thanks to its strong adhesive, this label is ideal for application on paper, cardboard, and plastic surfaces. Produced according to the stringent ISO 9001:2015 quality standard, the Label Lock High Residue labels can withstand temperatures ranging from -30°C to +70°C. Each label is printed with the text “SEALED” and features a unique sequential number for easy tracking and verification.

Manufactured to ISO 9001:2015 standards

Label Lock security labels rank among the most reliable in the industry. They are manufactured in the United Kingdom under UKAS-accredited supervision, ensuring consistent quality and traceability. Each production stage is closely monitored, and every batch undergoes thorough inspection before shipment. This meticulous process guarantees dependable performance for professional use.

Resistant to extreme temperatures

The Label Lock High Residue label maintains its performance across a wide range of conditions. It adheres securely even at -30°C and remains fully functional at temperatures up to +70°C. This makes it ideal for use in both cold storage and high-temperature logistics environments.

Permanent anti-tamper residue layer

The label consists of two layers bonded with a durable polymer adhesive. When removed, the layers separate, revealing the message “OPENED/VOID” while leaving a permanent residue layer on the surface. This ensures that any tampering attempt is clearly visible and irreversible. The Label Lock High Residue belongs to the High-Residue category — labels that leave behind a non-removable fraud detection layer. For applications requiring a clean surface after removal, the Label Lock Low Residue label is a suitable alternative.

Suitable for paper, cardboard, and plastic

Thanks to its powerful adhesive, the Label Lock High Residue label adheres excellently to boxes, envelopes, medical packaging, and films. It is perfect for securing valuable documents, pharmaceutical products, and confidential shipments. Any attempt at tampering becomes instantly visible, helping to prevent theft and damage.

Unique numbering and customization options

Each label is printed with a unique sequential number that is produced only once, ensuring full traceability and tamper resistance. Labels are available in blue and in three standard sizes:

• Small: 73 x 20 mm

• Medium: 98 x 30 mm

• Large: 148 x 45 mm
