When you need that extra measure of confidentiality and security, tamper-evident Tyvek® envelopes are the right choice. The tamper-evident seal is a deterrent to ensure mail confidentiality. Once the tamper-evident seal is broken, the word "OPENED" appears in the flap window, letting the receiver know that the envelope has been opened and confidentiality lost.

Recommended for:
confidential, sensitive or valuable documents and mail including human resources files, medical reports, financial statements, evidence/case files, contracts, certificates, legal documents and more.
