Level 3 Blue Security Bag Seal - China Suppliers and Factory for Advanced Anti-Counterfeiting Solutions

,

Product Description of Level 3 Security Bag Seal:
Our Level 3 security bag seal is manufactured using advanced anti-counterfeiting technology, making it a top choice for security-conscious applications. Sourced from reliable China suppliers, this seal features a base constructed from durable PET or PO anti-counterfeiting materials. After the release paper is removed, a strong membrane creates an effective seal, ideal for securing logistics bags and preventing unauthorized access.
One of the key features of this seal is its temperature-sensitive surface. If exposed to temperatures exceeding 60°C or during attempts to unlawfully open the bag with heat, the visible VOID mark transitions from white to red, immediately indicating tampering. Additionally, when temperatures drop to 0°C or below, or during a low-temperature breach attempt, the anti-counterfeiting markings will fade, ensuring dual temperature protection. This product is expertly crafted in our factory to meet rigorous quality standards, providing peace of mind for businesses that prioritize security.

When the bag is exposed to a low temperature of 0 degrees or less, or when you tries to open through a low temperature, the anti-counterfeiting characters will fade.

    Frequently Asked Questions

    Q What is a Level 3 Security Bag Seal and how does it differ from standard seals?
    A Level 3 Security Bag Seal is an advanced tamper-evident label that incorporates multiple security features including temperature-sensitive indicators, VOID hidden messages, and partial transfer technology. Unlike standard seals, it provides three layers of protection: anti-theft, anti-copy, and anti-counterfeit, making unauthorized opening immediately detectable.
    Q How does the temperature-sensitive feature of the security bag seal work?
    The seal's surface contains a temperature indicator layer. When exposed to temperatures of 60°C or above, the layer rapidly changes color — typically from white to red — providing a clear, conspicuous visual alert. Conversely, at temperatures of 0°C or below, the anti-counterfeiting characters will fade, preventing low-temperature tampering attempts.
    Q Can the Level 3 Security Bag Seal be customized in size, color, and printed text?
    Yes. The seal is fully customizable. Available colors include Red, Blue, Yellow, Matt Silver, and more. Hidden message options include VOID, OPEN VOID, OPENED, or fully custom text. Size can be tailored to your specific packaging requirements, and surface printing is also offered. Both OEM and ODM orders are accepted.
    Q What industries and applications are these security bag seals suitable for?
    Level 3 Security Bag Seals are widely used across numerous industries including IT electronics, electrical appliances, security, medicine, chemicals, retail shopping malls, and banking. They are ideal for logistics, aviation, express delivery, document sealing, letter security, and any application where unauthorized opening must be clearly identified.
    Q What material and adhesive are used in the Level 3 Security Bag Seal?
    The face stock is made from PET/PO material with a face film thickness of 25 microns, ensuring durability and tamper resistance. The adhesive used is hot melt adhesive, which provides strong bonding to packaging surfaces while ensuring the VOID pattern is clearly revealed upon any tampering attempt.
