FAQs
- How does a tamper-evident seal work?
- The envelope has a strip/flap that must be broken or altered to open—so any tampering is visible.
- Is Tyvek® still water-resistant with the tamper strip?
- Yes. The Tyvek material retains its durability; the tamper strip is designed to complement it without compromising protection.
- Can you print logos or confidential markings?
- Yes—spot or full-color printing is available. You can add “Confidential”, logos, or other messages.
- What sizes are available?
- Standard sizes (like #10, 9″×12″, 10″×13″) are in stock. Custom sizes can be made as needed.
- How secure is the tamper seal?
- Very—while not unbreakable, it provides strong visual deterrence and clearly shows unauthorized opening.
