Level 2 Black Thermo Ink Tamper Evident Bag Sealing Tape

This Bag Sealing Tape​perfect for companies requiring discreet yet robust security, this tape combines two key defenses to protect your shipments from unauthorized interference and tampering attempts.​

Black thermochromic ink offers high contrast color shift (e.g., black to red) for easy visual verification, with changes remaining irreversible.​
Optional sequential numbering available for enhanced traceability of your sealed bags.​
Rapid design support provided for custom VOIDOPEN text and ink color combinations, at no extra cost.​
Available in standard roll sizes or can be tailored to your exact production line requirements.​
