Product Description of Level 1 Security Bag Seal:
Introducing our Level 1 Security Bag Seal, designed to provide reliable anti-counterfeiting protection. Manufactured from high-quality PET or PO anti-counterfeiting materials, this security seal is ideal for use in security bags, logistics bags, and anti-tamper applications. The seal bonds securely with the membrane after the release paper is removed, creating a tamper-evident seal. Once the seal is disrupted, pre-set anti-counterfeiting messages such as VOID, VOIDOPEN, or customized patterns will be clearly visible on the tape's surface, leaving a lasting impression of the anti-counterfeiting information on the adhesive itself. This product showcases both solid (Yang version) and hollow (Yin version) designs, ensuring enhanced visual communication of security. As a trusted China supplier and factory, we ensure our Level 1 Security Bag Seals meet stringent quality standards to protect your assets effectively.

High-Quality Level 4 Security Bag Seal – China Suppliers
Introducing the advanced Level 4 security bag seal, expertly designed to provide anti-counterfeiting solutions for your security needs. This innovative seal bonds with the membrane after the release paper, creating a secure closure that protects against tampering. Manufactured from premium PET or PO anti-counterfeiting materials, this seal is ideal for security bags, logistics bags, and anti-disassembly applications.

The Level 4 security bag seal features a unique temperature-sensitive layer that activates at critical thresholds. When exposed to temperatures above 60 degrees Celsius, the seal’s blank area displays a vivid VOID message that turns red, indicating potential tampering or exposure to heat. Similarly, when subjected to temperatures below 0 degrees Celsius, the anti-counterfeiting characters will fade, serving as a clear warning against unauthorized access.

Additionally, if the security bag seal comes into contact with water or solvents, the tamper-evident markings will disappear, further protecting your valuable contents. As a reliable China supplier and factory, we are committed to delivering top-quality security solutions that meet your business needs. Choose our Level 4 security bag seal for your logistics and security requirements, and ensure peace of mind knowing your cargo is safe from tampering.
