Tamper-evident packaging incorporates structural features that provide undeniable, irreversible visual proof if a package has been opened or altered:
### Tamper-Evident Mechanisms:
1. Integrated Perforated Tear Strips: The box flap cannot be opened without permanently destroying a perforated zipper strip.
2. Destructible Security Label Seals: Ultra-fragile paper or foil stickers applied across box openings that tear into tiny fragments if peeled.
3. Void Security Labels: When peeled, chemical adhesive transfers the word "VOID" or "OPENED" onto the box surface.
4. Glued Tuck Flaps with Security Slits: Glue tabs with angled micro-slits that rip the board fibers visibly upon unauthorized opening.
### Critical for:
- Pharmaceuticals & over-the-counter health remedies
- Food, confectionery & meal kits
- High-value electronics & jewelry
- Cosmetics & personal hygiene products.
