Blue Security tape/Tamper-Evident Security Tape

Product discription of Security tape/Tamper-proof Security Tape : 
What is tamper-evident security packing tape? Unlike common packing tape, tamper-evident security packing tape cannot be removed or reapplied without leaving evidence, such as a 'void' or 'opened' message. Our tamper evident tape provides an anti-tamper seal for catons, bags, letters and soon. As an additional security measure, apply the tamper proof tape. Removing tamper evident tape will cause the tape to destroy itself leaving a message, reading: ‘opened' or ‘VOID’. This security text will appear on both the affixed surface and on the security tape itself. What's more, tamper proof tape indicates tampering by showing mis-alignment or even a broken seal. A broken safety seal indicates that an unauthorized person tried to open the box.
