It is designed to safeguard large quantities of medicine during bulk transportation, handling and storage, preventing physical damage while maintaining the integrity of the drugs inside.

Tertiary packaging is not consumer-facing and is primarily used for logistics and warehouse storage, ensuring that pharmaceuticals reach pharmacies, hospitals and distributors safely. This layer of packaging plays a significant role in supply chain efficiency, sustainability and cost-effectiveness, as it optimises space and enhances transportation security.

Common tertiary packaging materials in pharmaceuticals

Pallets – Standardised platforms used to stack multiple secondary packaging units, making it easier to move large quantities of pharmaceutical products using forklifts and pallet jacks.
Wooden crates – Provide additional protection for delicate or temperature-sensitive pharmaceutical products, such as vaccines or biologics, ensuring they are not damaged during long-distance transport.
Corrugated boxes – These sturdy, lightweight containers are commonly used to secure and stack multiple pharmaceutical products within tertiary packaging. They act as an additional protective layer, absorbing impact and reducing the risk of breakage during shipping.
Shrink-wrapped bundles – Often used to hold multiple cartons together on pallets, shrink wrap provides an extra layer of security to prevent tampering and movement during transport.

The importance of tertiary packaging in pharmaceuticals

Protects bulk shipments from external damage – External environmental factors such as moisture, temperature fluctuations and physical impacts can compromise pharmaceutical products. Tertiary packaging ensures that medicines remain in pristine condition throughout distribution.
Improves storage and logistics – By standardising packaging for bulk shipments, tertiary packaging helps optimise warehouse space and streamline distribution, reducing handling time and minimising operational costs.
