Serial Number Security Bag Tape is a tamper evident bag sealing tape designed for security bags, evidence bags, bank deposit bags, courier bags, cash bags, confidential envelopes, customs inspection bags, and high-value logistics packaging. It combines visible opening evidence with serial number printing, helping customers improve package traceability and security inspection.
Unlike ordinary bag sealing tape, serial number security bag tape can help each bag or package receive a unique identification code. When the bag is opened, peeled, resealed, heated, frozen, or attacked, the tape can show visible tamper evidence while the printed serial number supports tracking, inspection, and record management.
Serial Number Security Bag Tape uses a multi-layer tamper evident structure, including face film, hidden security message layer, adhesive system, release liner, printed serial number, barcode, QR code, or other variable data. After the tape is applied to the bag closure area, it creates a security seal that cannot be opened cleanly without leaving visible evidence.
If someone tries to open or remove the tape, the hidden VOID, OPENED, or custom security message appears. At the same time, the serial number or barcode helps inspectors identify the original bag, shipment, batch, department, location, or chain-of-custody record.
Serial number printing is important when customers need both tamper evidence and traceability. For evidence bags, bank bags, cash handling bags, and courier security bags, every package may need a unique record. A printed serial number helps reduce confusion, improve accountability, and support inspection during storage, transport, and delivery.
This material is especially suitable for customers who need visible opening evidence, unique bag identification, barcode scanning, QR code tracking, and OEM/ODM security bag tape customization.
Serial Number Security Bag Tape is commonly used for police evidence bags, forensic sample bags, bank deposit bags, cash transport bags, courier security bags, confidential document bags, customs inspection bags, airport security bags, medical sample bags, and high-value logistics packaging.
For chain-of-custody applications, the serial number helps connect the physical bag with inspection records. For banking and cash handling, it helps improve accountability. For logistics and courier packaging, it helps reduce disputes caused by unauthorized opening, missing goods, or package replacement.
Standard security bag tape mainly provides tamper evidence. Once the bag is opened, the tape can show a VOID message, residue mark, color change, or other visible evidence. However, without a unique code, it may be difficult to identify each individual bag during inspection.
Serial Number Security Bag Tape adds traceability to the tamper evident function. Each tape section, bag seal, or finished bag can carry a unique printed number, barcode, QR code, or variable data, making it more suitable for evidence control, banking, logistics tracking, and secure document transfer.
Hanksec can customize serial number security bag tape according to number format, barcode type, QR code layout, printing color, roll width, adhesive strength, hidden message, tape color, liner material, security level, and final bag sealing structure.
Common customization options include sequential numbers, repeated serial numbers, dual-number design, barcode plus number, QR code plus number, logo printing, warning text, custom hidden message, multi-direction barcode, twin seal, easy tear strip, writable surface, and special bag sealing structures.
Serial Number Security Bag Tape should be tested with the customer’s real bag-making and sealing process. Important production factors include roll width, roll tension, printing registration, barcode readability, number sequence accuracy, adhesive release, liner removal, cutting position, and machine running speed.
For automatic security bag production, stable printing and converting performance are important. Hanksec can provide sample testing support to help customers confirm serial number clarity, barcode scanning, adhesive bonding, hidden message effect, and final bag sealing performance before bulk production.
Before mass production, customers should test the tape on the real bag material. HDPE, LDPE, PE, co-extruded film, laminated film, recycled plastic, coated film, and printed bag surfaces may show different bonding and tamper evidence performance.
Important testing points include peel adhesion, VOID message clarity, serial number readability, barcode scanning, QR code scanning, ink durability, liner release force, adhesive bonding, machine stability, and final bag sealing strength. Testing under actual storage, transport, and handling conditions is recommended before confirming bulk orders.
