Security Tamper Evident Bags (STEBs) are specialized packaging solutions designed specifically for the aviation industry to secure Liquid, Aerosol, and Gel (LAG) products purchased at airport duty-free shops or on board aircraft. Developed in accordance with the strict guidelines set by the International Civil Aviation Organization (ICAO), STEBs ensure that duty-free purchases remain secure and untampered with during transit, particularly when passengers are transferring through multiple airports.
These bags feature advanced tamper-evident closures, unique serial numbers, and specific material requirements that make any unauthorized access immediately visible. By using STEBs, airports and airlines can comply with international aviation security regulations while providing a seamless shopping experience for international travelers.

ICAO Requirements for STEBs
To be recognized as a compliant STEB, the bag must meet rigorous standards established by ICAO. As a listed manufacturer of ICAO STEBs, Adsure Packaging ensures that every bag we produce adheres strictly to these international requirements:
- Material Specifications: The bags must be made from high-quality, transparent, and tear-resistant polyethylene (PE) film, typically with a minimum thickness of 50 microns, to withstand the rigors of air travel.
- Tamper-Evident Closure: The sealing tape must be highly sensitive. Any attempt to open the bag using heat, cold, solvents, or physical force must result in visible, irreversible damage to the seal, often revealing a hidden “VOID” message.
- Unique Identification: Each bag must feature a unique serial number and a corresponding barcode to facilitate tracking and tracing throughout the supply chain and passenger journey.
- Standardized Printing: The bags must display the official ICAO logo, the three-letter state code, and the manufacturer’s name, clearly identifying the origin and compliance of the packaging.
- Internal Pouch: A mandatory internal pocket must be included to securely hold the purchase receipt, ensuring it remains visible and protected alongside the LAG items.
