Level 2 Purple Security Bag Seal - Anti-Counterfeiting Solutions from China Suppliers and Factory

Level 2 Security Bag Seal Product Description:
The Level 2 security bag seal is designed with advanced anti-counterfeiting features, making it an essential solution for security applications. Manufactured with high-quality PET or PO materials in our China factory, this seal provides reliable protection against tampering. Once the release paper is removed, a strong membrane bonds to the substrate, ensuring an effective seal ideal for security bags, logistics bags, and anti-disassembly scenarios.
A standout feature of our security bag seal is its temperature-sensitive capability. Featuring a unique temperature indicator layer, the seal displays the word VOID in its blank area. If the bag encounters high temperatures exceeding 60 degrees Celsius or if there is an attempt to open it with heat, the temperature-sensitive layer responds quickly, changing color from white to bright red. This rapid color transformation is clear, highly visible, and serves as undeniable evidence of any unauthorized temperature interference. With our Level 2 security bag seal, you can trust in the integrity of your products while sourcing from reliable China suppliers.
