How to Choose Tamper Evident Bags: 5-Step Security Guide
When you how to choose tamper evident bags, the first question is not price or color—it is risk. A bag that works for a clothing return may fail inside an armored truck. Follow the five checkpoints below and every bag you buy will match both your threat level and your budget.
1. Identify the Threat Level
Start by listing what you are protecting and who might try to open it.
- Low-risk retail returns need a simple adhesive strip.
- High-risk cash-in-transit demands temper proof bags with dual-seal tape and hidden fibers.
Write the risk on paper; every later decision flows from this line.
2. Match the Closure Strength
Next, look at the seal.
- Single-use pressure-sensitive adhesive is fine for e-commerce.
- Dual-seal tape—one layer for shipping, one for final delivery—creates temper evident technology that screams “tampered” if anyone lifts the flap.
Check the peel force spec: 3 N for retail, 10 N+ for banks.
3. Check Industry Certifications
Regulations save time and lawsuits.
- ISO 17712 “H” level for cargo containers.
- C-TPAT for U.S. customs.
- FDA 21 CFR for pharmaceutical samples.
A compliant bag already contains lab-tested temper evident technology; you do not have to reinvent it.
4. Review Tamper Evidence Features
Features tell the story after the seal is broken.
- Hidden VOID print appears only when the film is peeled.
- Thermochromic ink changes color if frozen or heated.
- Sequential numbers and barcodes create an unbreakable chain of custody.
Ask the supplier for a short video of each feature in action.
5. Balance Cost vs. Protection
Finally, run the numbers.
- ZOLO’s 400,000 m² monthly output keeps per-bag cost low.
- Custom logos add pennies yet double brand value.
- Rush orders ship in five days, so you never pay for air freight unless you choose to.
