Tamper Evident Bags
Qline tamper evident envelopes are designed with advanced security features that clearly show any unauthorized access. These envelopes provide a strong visual indication of tampering, ensuring the safety of the contents during handling and transit.
They are manufactured using co-extruded polyethylene films with a black inner layer and white outer surface, and are also available in transparent options. Each envelope includes a hot-melt adhesive strip that enables quick sealing and creates a permanent, tamper-evident closure.
A special security seal is applied that reveals a clear VOID message when tampering is attempted. Once sealed, the envelope cannot be opened without tearing or cutting, and any interference results in visible marks, confirming that the package has been compromised.
These bags are widely used for transit of highly confidential documents, precious items like:
- Examination Papers.
- Passport.
- Evidence For Police Dept.
- Batch Samples.
- Credit/debit card.
- Currency.
- Confidential Documents.
- Aviation.
- Forensic Labs.
