CONSTANTIA Tamper-Evident Opening System

Solutions for brand protection.

Peelable lidding foil with integrated tamper evident feature.



  • Tamper evident feature is activated by peeling off the lid from the thermoformed tray
  • In combination with other anti-counterfeiting features reliable protection against illegal recycling and counterfeiting
  • Smooth opening like conventional peel to open packs



The opening is ensured through a peelable coating in the opening area (pink area in the picture).

As soon as the tray is opened further down the lid foil is tearing. This effect is caused by specific heat-seal strength in different areas on the tray.

The peelable coating is transferred to the thermoformed tray.
