Premium Seal Label (Tax Stamp / Closure Label) for Soft Pack
The Seal Label (often used as a Tax Stamp or "U-Seal") is the critical functional and regulatory component for soft-pack cigarette packaging. Applied across the top of the pack, it serves as the primary closure mechanism, a tamper-evident seal, and a platform for government-mandated tax compliance. Our seal labels are engineered with high-strength adhesives and specialized paper stocks that ensure a secure bond to the overwrap or paper label, while maintaining clean tear-lines for the consumer upon first opening.
