Frequently Asked Questions (FAQ)
What is an anti-counterfeiting security bag and how does it work?
An anti-counterfeiting security bag is a tamper-evident packaging solution made from LDPE or PP material. It features hidden messages (such as VOID or OPENED) that appear on the bag's surface once it has been illegally opened, providing immediate visual proof of tampering. Each bag is also assigned a unique serial number and barcode for full traceability.
Can the size and printing of the security bag be customized?
Yes. The bag size can be fully customized to meet your specific requirements. Surface printing is also available, and both OEM and ODM services are supported. You can choose custom hidden message text, colors, logos, and other branding elements to suit your business needs.
What industries commonly use anti-counterfeiting security bags?
Anti-counterfeiting security bags are widely used across multiple industries, including banking, jewelry, airport duty-free shops, government departments, aviation, express logistics, and safety management. They are ideal for protecting cash, valuable items, important documents, and any goods requiring secure and traceable packaging.
What hidden message options are available for the security bag?
The standard hidden message options include VOID, OPEN VOID, and OPENED. Custom text can also be arranged upon request. These messages are concealed under the adhesive seal and only become visible if the bag is tampered with or forcibly opened, making forgery or re-sealing immediately detectable.
How are the security bags delivered, and what is the lead time?
Security bags can be delivered by air or by sea, depending on your location and urgency. Lead times vary based on order quantity and customization requirements. Please contact us directly via the inquiry form to get an accurate delivery timeline and shipping quote for your specific order.
Can the security bag be resealed or reused after opening?
No. The anti-counterfeiting security bag is designed for single use only. Once the bag is opened, the adhesive seal is permanently damaged and the printed anti-counterfeiting characters or patterns will be deformed or destroyed, making any attempt at resealing clearly visible. This ensures the integrity and security of the contents at all times.
