Airport and duty-free packaging has different security requirements from ordinary retail packaging. STEB bags, or Security Tamper-Evident Bags, are designed for eligible duty-free liquids, aerosols and gels (LAGs) and help indicate whether a package has been opened or interfered with during travel. However, a STEB does not guarantee acceptance at every airport, airline or transit route, so passengers and retailers must follow the applicable security rules.
What Are STEB Bags?
STEB (Security Tamper-Evident Bag) bags are transparent, security-focused bags used to package eligible duty-free LAGs. They feature a tamper-evident closure and may include serial numbers, barcodes and receipt sections. Unlike ordinary shopping bags, they provide visible tamper evidence and traceability for relevant transfer LAGs, subject to applicable airport security procedures and technical specifications.
Why Are STEB Bags Used in Duty-Free and Airport Retail?
Security during passenger travel
A sealed bag helps keep eligible duty-free LAG purchases together after purchase and during onward travel.
Visible evidence of interference
The closure is designed to show signs if someone attempts to access the contents. A STEB is tamper-evident, not tamper-proof.
Secure handling of duty-free LAGs
LAGs include liquids, aerosols and gels such as perfume, spirits, skincare products and other eligible duty-free items. The bag helps support their handling during security checks.
Identification and traceability
Serial numbers, barcodes and purchase receipts can connect the package with the transaction and support operational checks.
Support for airport procedures
STEBs can help retailers and security personnel follow established procedures, but requirements differ by country, airport, airline and journey route
How Do STEB Bags Work?
- The duty-free product and required purchase documentation are placed inside the bag.
- The bag is closed using its security seal.
- The closure and identification features help indicate attempted opening.
- The passenger keeps the bag sealed and presents it for inspection when required.
- Airport and airline instructions continue to apply throughout the journey.
Key Security Features of STEB Bags
Tamper-evident closure
The security seal provides visible evidence of attempted access.
Sequential numbering
Unique numbering supports identification, record-keeping and traceability.
Barcode capability
Barcodes can support scanning, transaction matching and operational tracking.
Thermochromic security tape
A heat-sensitive tape may provide an additional indication of certain tampering attempts. The exact level and configuration must be confirmed before ordering.
Twin seal
A twin-seal structure can add another layer of closure security.
Receipt section
A receipt section helps keep proof of purchase with the duty-free contents.
Writable surface
A writable area supports operational notes, identification or handling instructions.
