Qu'est-ce qu'une boîte isotherme sous vide et comment ça marche?
A vacuum insulated box is a passive cooler that uses a vacuum sealed microporous core, barrier films and phase change materials to maintain stable temperatures for days. The inner core consists of highly porous silica or glass fibres pressed under vacuum, eliminating air molecules that would otherwise transfer heat. This core is wrapped in multiple barrier films—typically aluminium and polyethylene—to prevent gas permeation and moisture ingress. A robust outer shell made of polypropylene or aluminium protects the delicate core, while PCMs such as gel packs or eutectic plates line the inner surfaces and absorb heat during transit. With thermal conductivity as low as 0.004–0.008 W/(m·K), a well configured vacuum box can maintain temperatures between 2 °C et 8 °C or even frozen ranges for 7–10 jours, outperforming traditional foam coolers.
Explication élargie
Think of a vacuum insulated box as a supersized thermos. In a regular thermos, a vacuum layer prevents heat transfer; the same principle applies here but at a logistics scale. Le microporous core provides a network of tiny voids sealed in a vacuum, greatly reducing heat conduction. Surrounding this core is a multi layer barrier film that keeps the vacuum intact and prevents moisture ingress. UN support structure, often honeycomb boards or rigid foam, protects the fragile core from compression during transport. Le coque extérieure of polypropylene or aluminium provides mechanical strength and puncture resistance. Enfin, PCMS-des sachets de gel, salt solutions or dry ice—buffer internal temperatures by absorbing or releasing latent heat. When the outside temperature rises, the PCM melts and absorbs heat; when it drops, the PCM freezes and releases heat, keeping the payload within a narrow band.

Why Use a Vacuum Insulated Box for Last Mile Delivery?
Vacuum insulated boxes are ideal for last mile delivery because they provide long lasting temperature stability with minimal energy, reducing spoilage and operational costs. In the e grocery market, high performance systems such as the UTZ THERMOBOX use vacuum insulation panels with integrated PCMs to maintain stable temperatures for 48 heures ou plus. Thanks to the efficiency of vacuum insulation, a single cooling element is often sufficient even for deep freeze applications. While the initial cost of these boxes is higher than simpler options, they require less energy for pre cooling and fewer ice packs, so the total cost of ownership drops significantly. A white paper analysis showed that a high performance vacuum insulated solution can pay for itself within one to three and a half years.
Explication élargie
Last mile delivery—getting products from distribution centers to customers’ doors—is the most critical and expensive part of the cold chain. Détérioration, temperature excursions and regulatory non compliance can erode margins and damage trust. Vacuum insulated boxes mitigate these risks by extending temperature hold times, reducing the number of cooling elements needed and ensuring consistent quality. With vacuum insulation panels, the box’s walls can be one fifth as thick as foam while offering five to ten times better insulation. This means that more payload can fit in the same external dimensions, increasing delivery efficiency and reducing freight costs. De plus, because the boxes are lighter, carriers may charge less for shipping, and handlers find them easier to manoeuvre. For businesses with high delivery volumes, the reduction in gel packs and the elimination of dry ice translate into significant operational savings.
Vacuum insulated boxes also support sustainability goals. Passive systems eliminate the need for diesel powered refrigeration units during last mile transport. Reusable VIP carriers replace mountains of single use foam packaging; one supplier reported that switching to reusable panels reduced packaging waste by 40 % and lowered shipping costs while maintaining 2 °C–8 °C for monoclonal antibody therapies. Such reductions directly improve your company’s carbon footprint and align with regulations increasingly requiring eco friendly solutions.
