Tamper Evident Bag Sealing Tape is designed for evidence bags, bank deposit bags, courier bags, cash bags, document bags, and high-value security packaging. Once the bag is opened, peeled, heated, frozen, cut, or attacked with liquid, the tape can show visible and irreversible tamper evidence.
Hanksec supplies tamper evident bag sealing tape in different security levels, including basic VOID transfer tape, heat-sensitive tape, cold-indication tape, water-sensitive tape, solvent-sensitive tape, serial-number tape, barcode tape, and multi-layer security bag closure solutions for OEM and ODM packaging projects.
Security bag tape, also known as tamper evident bag sealing tape, is designed to provide visible and irreversible evidence when a security bag is opened, peeled, heated, frozen, exposed to liquid, or mechanically attacked.
For B2B customers, choosing the right security bag tape is not only about price. The correct choice depends on the bag material, security risk, application industry, sealing method, required tamper evidence, and production process.
HANKSEC provides different security levels for security bag manufacturers, plastic bag factories, packaging factories, distributors, and duty-free bag suppliers.
| Security Level | Security Grade | Main Tamper Evidence Features | Recommended Applications | How Customers Should Choose |
|---|---|---|---|---|
| Level 1 Security Bag Tape | Basic Security | Provides basic sealing and visible tamper indication. When the bag is opened or peeled, a VOID / OPEN VOID message or broken-seal evidence appears. | Retail security bags, standard courier bags, low-risk document bags, general packaging bags | Suitable when the customer needs basic tamper evidence at a cost-effective level. It is recommended for low-to-medium risk packaging where visible opening evidence is required but advanced anti-tamper layers are not necessary. |
| Level 2 Security Bag Tape | Standard Security | Provides VOID tamper evidence and improved cold-condition performance. The tape can show clear tamper evidence when removal is attempted, including under lower temperature conditions. | Courier bags, e-commerce security bags, document bags, warehouse transfer bags, general logistics bags | Suitable when the customer needs better security than basic sealing, especially for bags used in logistics or colder environments. It is a practical option for standard security bag production. |
| Level 3 Security Bag Tape | Enhanced Security | Combines VOID tamper evidence with heat-sensitive or temperature-indicating features. It helps expose attempts to open the bag using heat, such as hot air gun or heating tools. | Cash bags, logistics security bags, valuables transport bags, pharmaceutical sample bags, higher-risk courier bags | Suitable when the customer is concerned about heat-based tampering. It is recommended for applications where attackers may try to open the bag by heating. |
| Level 4 Security Bag Tape | High Security | Combines multiple tamper evidence layers such as VOID message, cold indication, heat indication, and water or solvent-sensitive features. It provides stronger evidence against peeling, freezing, heating, and liquid attacks. | Bank deposit bags, evidence bags, examination bags, hospital patient belonging bags, cash bags, coin bags, duty-free security bags | Suitable for customers requiring high-security protection. It is recommended for valuable items, confidential documents, law enforcement evidence, banking, medical, and regulated security packaging. |
| Level 5 Security Bag Tape | Advanced Security | Adds additional authentication or anti-counterfeit features such as hidden UV printing, customized security patterns, serial numbers, or advanced security cuts. It provides both visible tamper evidence and covert verification. | High-value cash transport, confidential documents, government packaging, brand-protection bags, premium security bags, critical logistics | Suitable when the customer requires both tamper evidence and product authentication. It is recommended for customers who need a stronger anti-counterfeit layer and traceability features. |
| Level 6 Security Bag Tape | Maximum Security | Provides multi-layer protection by combining VOID evidence, cold/heat response, water or solvent indication, security cuts, hidden UV features, serial tracking, and customized anti-tamper structures. | Evidence chain-of-custody bags, high-value asset transport, pharmaceutical security bags, customs control bags, aviation security bags, top-level confidential packaging | Suitable for customers with the highest security requirements. It is recommended when the bag must resist multiple tampering methods and provide clear, irreversible, and layered evidence of unauthorized access. |
