Tamper Evident Vial Labels for Regulated Products and Clinical Packaging

Protect medicines and small-format packaging with visible, irreversible tamper security seals built for regulated industries.

Tamper evident dumbbell vial labels with unique VOID messages, destructible materials, and full compliance. Made in the UK. Easy to apply by hand or machine.

Why You Need Tamper Seals for High Risk Packaging

Small packaging requires big protection. TamperTech’s tamper evident vial labels are engineered to deliver high-performance security for vials, injectables, ampoules, and other small containers used across pharmaceutical, clinical trial, and biotech supply chains.

Our dumbbell-style tamper evident labels secure closures and body simultaneously, making unauthorised access or tampering attempts instantly visible. Whether you’re producing 1,000 units or 1 million, TamperTech provides scalable vial label solutions that protect your product, your patient, and your brand.

Why Tamper Evident Vial Labels Are Critical

In pharmaceutical and clinical applications, the smallest breach can lead to:

  • Risk to patient safety

  • Regulatory compliance violations

  • Costly product recalls

  • Reputational damage

  • Legal liability

TamperTech vial labels are designed to eliminate these risks. We manufacture in the UK under ISO 9001 quality standards, offering reliable, validated security labelling for sensitive and high-value packaging formats.

How They Work

  1. Apply the dumbbell label around the neck and body of the vial

  2. Once applied, the label forms a secure bond across both areas

  3. Any attempt to open or tamper with the vial results in:

    • A visible VOID message

    • Material tearing or irreversible distortion

    • Covert or overt evidence of access

These labels cannot be reapplied or removed cleanly, ensuring a clear signal of breach to quality control teams, regulators, and end users.

Case Study: Biotech Firm Improves Inspection Rates with Custom Dumbbell Seals

A fast-growing UK-based biotech company was preparing a new clinical trial and needed to improve security across its injectable product vials. Manual inspection had missed tampering on two sample returns, creating concern around compliance.

TamperTech supplied custom dumbbell labels with a covert warning message revealed only on tampering, plus serialised batch codes for tracking.

Results after rollout:

  • 100% detection of interference in mock audits

  • Labels integrated into existing semi-automatic labeller

  • Batch serials linked to CRM for full traceability

  • MHRA submission accepted without packaging concerns

The company has since standardised TamperTech labels across all early-phase trial packaging.
