Component Specifications

Definition
A specialized security component designed for pharmaceutical vials that provides irreversible visual indication when the container has been opened or tampered with, ensuring product integrity and patient safety by preventing contamination, substitution, or adulteration of sterile pharmaceutical products.
Working Principle
The seal employs a frangible mechanism that breaks or shows permanent deformation when the vial closure is removed or manipulated. This creates visible evidence that cannot be restored to its original state, typically through breakaway bands, tear strips, or color-changing indicators that activate upon opening.
Materials
Typically made from aluminum-polymer laminates, induction-seal foils (aluminum foil with heat-seal coating), or specialized plastics with tamper-indicating features. Materials must be compatible with pharmaceutical products and sterilization processes.
Technical Parameters
  • Diameter 13-32 mm (standard vial sizes)
  • Thickness 0.05-0.15 mm
  • Break Force 8-12 N (for frangible seals)
  • Seal Strength ≥ 15 N
  • Temperature Resistance -40°C to 121°C
  • Sterilization Compatibility Autoclave, Gamma, ETO
Standards
ISO 8362-4, ISO 8871, USP <381>, EP 3.2.9, DIN 58361-4
