Self-adhesive Anti-tamper Label Avery L6113 — Polyester 45.7×21.2 mm, 960 pcs (20 sheets)

Avery Anti-tamper Label L6113 are durable self-adhesive polyester labels designed for laser printers. The labels are white, tear-resistant and constructed so that an attempted removal reveals a visible "STOP" message while a lower layer remains bonded to the surface, indicating tampering. Each label measures 45.7 x 21.2 mm and the pack contains 960 labels supplied on 20 sheets (48 labels per sheet).

Advantages

The polyester material resists tearing and offers reliable adhesion for secure labelling. The special multi-layer construction exposes a clear tamper indicator when removal is attempted, helping protect products, packaging and documents against unauthorized access. Labels are compatible with laser printers and come in a standard white finish for clear printing of text and codes.

Suitable for

• Security sealing of packaging and envelopes
• Asset tagging where tamper evidence is required
• Product warranty and guarantee seals
• Document protection and evidence marking

When it may not be suitable

These labels are designed for surfaces that accept strong adhesive bonds; they may not adhere well to very rough, highly textured or contaminated surfaces. They are intended for laser printing and polyester material, so they are not optimized for use on thermal or inkjet printers.

What to consider before purchase

• Confirm laser printer compatibility and correct printer settings for polyester media
• Check that target surfaces are clean, dry and not highly textured
• Verify label size is suitable for your layout and required printed content

Recommendations

For best results, store labels flat in a cool, dry place and test print one sheet to confirm alignment and print quality before processing the full batch. Apply to smooth, degreased surfaces for optimal adhesion and tamper evidence.
