Scotch 3771 "If Seal Is Broken" Printed Packaging Tape

Tamper-evident packaging tape

This white polypropylene tape carries a bold red warning that reads "If seal is broken, check contents before accepting." The printed message alerts handlers to inspect high-value shipments before acceptance and discourages theft during transit. It is suited to warehouses, fulfilment centres and any operation that needs visible evidence of package integrity. Each unit supplies one roll for immediate use.

Moisture and abrasion resistance

The polypropylene backing resists moisture, chemicals and scuffing so the printed warning stays legible through handling and storage. Adhesion holds firmly on corrugated cartons and similar surfaces under normal shipping stresses. The tape maintains its seal across temperature and humidity changes typical of warehouse and carrier networks. No special dispenser is required beyond a standard hand-held unit.

Replaces plain clear or brown box tape

Operations that currently seal cartons with unprinted tape gain an instant visual deterrent and a clear instruction for recipients. The upgrade is worthwhile when shipments contain valuable or sensitive items and the cost of a disputed delivery outweighs the small price difference. It is not intended for applications that require tamper-proof security seals, serialised tracking or high-temperature splicing.
