Level 2 Purple Security Bag Seal - China Factory Suppliers with Advanced Anti-Counterfeiting Features

,

Product Description of Level 2 Security Bag Seal:
The Level 2 security bag seal is engineered with advanced anti-counterfeiting features, making it an essential choice for those seeking reliable security solutions. Manufactured in China by top suppliers, this product utilizes a substrate crafted from PET or PO anti-counterfeiting materials. Once the release paper is removed, a durable membrane is bonded to create a seal that ensures maximum protection against tampering. Ideal for security bags, logistics bags, and anti-disassembly applications, this seal is designed for high security requirements.
A standout feature of this security bag seal is its temperature-sensitive functionality. The seal's surface includes a temperature indicator layer, with the word VOID visibly printed in the blank area. When exposed to temperatures exceeding 60 degrees Celsius or subjected to high-temperature opening attempts, the temperature-sensitive layer promptly reacts. This reaction results in a visible color change from white to red, providing quick, clear, and intuitive evidence of any unauthorized high-temperature tampering. Trust in our product, manufactured by a leading factory in China, for your security needs.

    Frequently Asked Questions

    What is a Level 2 Security Bag Seal?
    It is a high-security tamper-evident label designed for bags and packaging. It features a temperature-sensitive layer and hidden "VOID" messages that appear if someone attempts to open or tamper with the seal using heat or physical force.
    How does the temperature indicator work?
    The seal contains a specialized layer that reacts to heat. If the temperature reaches 60°C or higher (a common method used by thieves to peel off labels), the layer instantly turns from white to red, providing clear evidence of tampering.
    Can the hidden message be customized?
    Yes, while standard messages include "VOID", "OPEN VOID", or "OPENED", we offer customization options to include your specific brand name or custom text as the hidden message.
    What industries typically use these seals?
    These seals are widely used in banking (cash bags), logistics (express parcels), IT electronics, medical supplies, and aviation for securing sensitive documents and high-value goods.
    Do you offer different colors and sizes?
    Absolutely. We provide standard colors like red, blue, and yellow, as well as matt silver. Both the dimensions and the colors can be fully customized to meet your specific packaging requirements.
    What is the difference between partial and full transfer?
    This specific Level 2 seal uses Partial Transfer, meaning when removed, part of the adhesive and the hidden message stay on the surface of the bag, while the rest remains on the film, making it impossible to reseal without leaving a trace.
