Key Features
Description
High-Security Envelopes
Lockwise High-Security Envelopes are designed for the protection, custody and transport of documents and valuable items. The high-adhesion self-adhesive closure system acts as a seal: once closed, the envelope cannot be opened without permanently damaging the material or revealing signs of tampering.
Any attempt to open it—whether mechanical, thermal or chemical—is exposed in an obvious and irreversible way. The sealing system is destroyed or reveals an alert message that cannot be concealed.
They support custom design in any size with company name printing, logos, sequential numbering and barcodes for full traceability on every shipment.
Applications
Sealing solutions for multiple sectors and industries.
