Swiss Post and va-Q-tec
Protecting medicines in the last mile with reusable passive thermal boxes
Climate-related network risk: Heat exposure, last-mile temperature excursions, handover delays and dependence on active cooling in pharmaceutical distribution
Solution pathway: Reusable passive thermal packaging, vacuum insulation, phase change materials and parcel-level temperature protection
Business type: National logistics provider and specialist thermal packaging company
Sector: Pharmaceutical logistics, healthcare delivery and temperature-controlled transport
Geography: Switzerland and Liechtenstein
In practice
Pharmaceutical logistics has a low tolerance for temperature failure. Many medicines must remain within strict temperature ranges throughout storage, handling and delivery. If they are exposed to excessive heat, cold or delays, product stability and patient safety can be affected. This creates a particular challenge in last-mile delivery, where parcels may move through depots, vehicles, handovers and household delivery routes that are harder to control than warehouses or specialist freight lanes.
Swiss Post addressed this challenge through its ThermoCare service, developed with va-Q-tec. The service uses reusable, vacuum-insulated transport boxes designed for temperature-sensitive human and veterinary medicines. The boxes can support cold-chain shipments at 2°C to 8°C and ambient pharmaceutical shipments at 15°C to 25°C.
The technology combines high-performance vacuum insulation panels with phase change materials. This allows the box itself to maintain the required temperature range for a defined period without external power during transport. In practice, this means thermal protection is built around the parcel or unit load, rather than relying only on refrigerated vehicles, warehouse cooling or active systems throughout the route.
For climate resilience, this matters because last-mile routes are increasingly exposed to hot weather, traffic disruption and operational delays. A medicine parcel may pass through several touchpoints before reaching a patient, pharmacy or healthcare provider. Passive thermal packaging adds a protective buffer at the point where temperature control can be weakest: the final movement from logistics network to recipient.
The case is useful for this section because it shows that cold chain resilience does not always need to be built only into large infrastructure. For sensitive products, resilience can also be designed into the packaging system itself. This can reduce dependence on active cooling, make temperature-controlled delivery more flexible, and help maintain product integrity across mixed parcel networks.
Why this example was selected
This case study was selected because Swiss Post and va-Q-tec provide a well-documented, operational example of reusable passive thermal packaging at scale. Swiss Post publicly offers ThermoCare as a passive temperature-controlled shipping service for medicines, including GDP-compliant options for both cold and ambient pharmaceutical temperature ranges.
The case has also been published by va-Q-tec as a Swiss Post case study. va-Q-tec reports that Swiss Post has used around 8,000 reusable ThermoCare boxes since 2017 and completed more than one million shipments of temperature-sensitive pharmaceuticals. The company also reports that the system can reduce environmental impact compared with actively cooled vehicles, while reducing packaging waste through reuse, repair and closed-loop handling.
This external documentation makes the case relevant for the platform because it is not only a theoretical packaging solution. It is a live logistics service used in regulated pharmaceutical distribution, with defined temperature ranges, service procedures, reuse systems and published performance claims.
The example is especially relevant for businesses moving medicines, diagnostics, vaccines, biologics, specialist foods or other temperature-sensitive goods. It shows how companies can add thermal resilience at the weakest point in the route: the parcel, box or unit load that moves through the final mile.
Key lesson
Businesses moving temperature-sensitive goods should identify the weakest points in the chain and add protection there. Passive thermal packaging can provide an additional safeguard during transfers, delays and last-mile delivery, reducing reliance on active cooling alone.
