What the AI looks for in Mail Bags
- Lockability
- For confidential mail, choose a keyed lock or a zipper whose pull locks to a fixed tab, not a plain zipper. A plain zipper offers no protection against casual opening.
- Carry method
- Top handles for desk-to-desk runs; a shoulder strap for anyone walking a route. The wrong carry style causes fatigue and drops on longer runs.
- Fits standard documents
- The interior should hold flat letter or legal folders, depending on what you send. Folded documents and bent envelopes are the usual complaint with small bags.
- Label or ID window
- Needed when the same bags rotate among departments or branches. It keeps the bag routed correctly without loose tags.
Brands that matter
- MMF Industries: Locking bags for banking and office use.
- ControlTek: Reusable and tamper-evident security bags.
What to avoid
- Vinyl bags for daily outdoor courier runs
- Bags with a lock but stitched seams that can be pried open
