Security Evidence Bags — Key Features
Each bag will be printed with a unique and consecutive barcode and serial number, which is used for recording and tracking purposes. The sides of the bags are heat-sealed and are printed with anti-pull patterns and text to prevent the sides from being illegally opened. Once sealed, the bag can be opened at room temperature.
When the seal is broken, the adhesive area displays a security word such as "VOID", enabling safer and more effective storage and transportation of sensitive items — including bank documents, checks, police evidence, confidential records, and national examination papers.

Frequently Asked Questions (FAQ)
Q
What materials are Security Evidence Bags made of?
Security Evidence Bags are made from LDPE (Low-Density Polyethylene) or PP (Polypropylene) as the face stock, with a PET release liner. These materials provide excellent durability, tamper-evidence, and chemical resistance suitable for secure packaging applications.
Q
How does the tamper-evident feature work on these security bags?
Once the bag is sealed, the adhesive closure is designed so that any attempt to open it will reveal a hidden security message such as "VOID" or "OPENED" on the adhesive area. This makes any unauthorized access immediately visible and provides clear evidence of tampering.
Q
Can Security Evidence Bags be customized with our company logo or specific size?
Yes, both OEM and ODM services are available. You can customize the bag size, surface printing (including your company logo and branding), and the hidden security message text (e.g., VOID, OPEN VOID, OPENED, or a custom message). Please contact us with your specific requirements for a tailored quote.
