What is Duty Free Bag?
Duty free bag—formally known as a Security Tamper-Evident Bag (STEB)—is a sealed, transparent plastic pouch designed to securely hold duty-free items like perfumes, liquor, cosmetics, or electronics.
These steb bags are widely used in international airports to comply with aviation security regulations concerning the transport of liquids and gels, especially when passengers are transiting through multiple countries.
Duty free bag is more than just a plastic pouch—it’s an internationally accepted, tamper-evident packaging solution designed specifically to help travelers transport duty-free goods across borders safely and legally.
At EcoSecurityTape, we specialize in delivering OEM duty free bags tailored to your brand’s specifications—whether you’re an airport retailer, cosmetic brand, or airline partner.
We help you consolidate supply from trusted Chinese manufacturers, offer low MOQ for testing, and provide global delivery support.

Duty Free Bag Design & Application
Our duty free bags are engineered with proprietary tamper-evident features—including irreversible seal damage, barcode tracking, and heat/cold sensitivity—providing consistent protection and full traceability across secure packaging workflows.
Each bag is manufactured under strict quality control using high-clarity co-extruded film, ensuring that any unauthorized attempt to access the contents will leave visible evidence. The embedded barcode system allows for real-time tracking, audit trails, and quick verification at every checkpoint.
Additionally, our heat/cold-reactive adhesives respond to temperature tampering attempts, adding another layer of protection. Whether you’re transporting liquids, luxury goods, or sensitive documents, our duty free bags meet the highest standards set by ICAO and IATA regulations—making them ideal for airports, bonded warehouses, and government export operations.
We also offer customizable options including printed branding, QR codes, multilingual warnings, and pouch dividers—allowing you to align security, compliance, and brand identity in one integrated solution.
Barcode Trackable Number
Our duty free bags include tear-off sections with serial numbers and barcodes for easy tracking, verification, and identification during global transit.

Cold and Heat Tamper-Evident
Our duty free bags resist tampering via heat or cold. Temperature attacks cause visible, irreversible damage to reveal any breach during transit.

Waterproof/ Liquid Proof
Made from high-grade PE/PO film, our duty free bags provide reliable protection against water and liquid penetration, keeping contents dry and secure in transit.
