What Is a VIP Container and Why Does It Matter?
A Brief Definition
A vacuum insulation panel (VIP) container is a rigid shipping box whose walls are lined with thin vacuum sealed panels. Each panel contains a porous core (often microporous silica or glass fibres) that is evacuated of air and sealed within a multi layer barrier film. Removing air dramatically reduces conduction, so heat transfer occurs primarily through the solid matrix. Manufacturers assemble multiple panels into a box and pair them with phase change materials (PCMs)—gel packs, ice packs or dry ice—to absorb and release heat. This combination yields a lightweight container that can maintain internal temperatures for days.
Core Components of VIP Containers
| Component | Description | Why It Matters |
| VIP Core | Microporous silica or glass fibres evacuated to near vacuum | Provides extremely low thermal conductivity (~5 mW/m·K) to delay heat transfer. |
| Barrier Film | Multi layer laminate (aluminium foil + polymers) that blocks gas ingress and reflects radiant heat | Maintains the vacuum seal and reduces radiant transfer, ensuring long term performance. |
| Support Structure | Spacers or aerogel enhanced cores prevent panel collapse under vacuum | Maintains panel shape and insulation integrity during handling. |
| Outer Shell | Corrugated plastic, fiberboard or expanded polypropylene (EPP) casing protects VIP panels from punctures and moisture | Adds durability and reusability to the container. |
| Phase Change Materials | Gel packs, dry ice or specialized PCM packs placed around the payload | Absorb/release latent heat to stabilize internal temperature for long durations. |
Why VIPs Are a Game Changer
Experts call VIP technology a breakthrough because the vacuum core allows thinner insulation layers while delivering superior thermal performance. According to the ColdChainPacking report, VIPs enable wall thickness of 10–15 mm, 50–70 % thinner than polyurethane foam or EPS. This reduction means more internal space for products or less coolant weight—critical factors for air cargo where space and weight drive cost. Sofrigam’s analysis highlights that VIP boxes maintain required temperature ranges for 7–10 days, two to three times longer than the best conventional insulation. With thinner walls, shippers can either increase payload volume or reduce refrigerant mass, directly improving pack out efficiency.
Advantages of VIP Containers over Traditional Insulation
Comparative Performance
| Insulation Material | Thermal Conductivity (approx.) | Wall Thickness for 72 h Hold | Practical Implication |
| Expanded Polystyrene (EPS) | ~36 mW/m·K (8× higher than VIP) | 30–40 mm | Low cost; easy to cut; but heavy, bulky and limited to 2–3 days hold time. |
| Polyurethane Foam (PUR) | ~22 mW/m·K | 25–35 mm | Moderate cost and rigidity; hold time about 3–5 days. |
| Vacuum Insulation Panel (VIP) | ≈5 mW/m·K | 10–15 mm (50–70 % thinner) | Higher cost and fragility; extended hold time 7–10 days; weight and volume savings. |
Key Benefits for Pack Out Optimization
Extended Duration – VIP containers maintain temperature far longer than foam coolers, allowing shipments across longer routes or extended dwell times during customs clearance.
Space Efficiency – Thinner walls free up internal volume; you can pack more products per container or ship smaller boxes for the same payload. A sample calculation shows that replacing a 20 mm EPS cooler with a 10 mm VIP reduces PCM mass by more than half and adds extra payload volume.
Weight Reduction – Lower insulation thickness and reduced PCM mass cut total shipment weight. This directly lowers air freight costs and decreases fuel consumption.
Consistency – VIPs provide stable temperature profiles with minimal fluctuations when paired with suitable PCMs. This reliability protects high value pharmaceuticals and biologics from temperature excursions.
High Value Protection – For life saving vaccines, biologics and specialty foods, the cost of product loss far exceeds container price. VIP reliability justifies investment.
Potential Drawbacks
Despite these benefits, VIP containers have limitations:
Fragility – Panels are brittle and require protective casings or foam layers to prevent punctures.
Higher Cost – VIPs are more expensive upfront than EPS or PUR; however, cost amortizes over multiple reuses and reduced product loss.
Shape Constraints – Panels cannot be easily cut or bent, complicating custom box assembly.
Weight – Core materials have higher density (150–250 kg/m³) compared with foams; design optimization is essential.
Environmental Footprint – Producing pyrogenic silica is energy intensive, though recycling the core can reduce ecological impact by up to 95 %.
Pack Out Optimization Strategies Using VIP Containers
1. Evaluate Your Product’s Thermal Profile
For each shipment, identify the required temperature range and duration. Pharmaceuticals often need 2–8 °C; frozen foods may require –18 °C, and ultra cold biologics may need –70 °C. VIP boxes can hold these ranges for 7–10 days or, in hybrid designs, 72 + hours with thinner PCMs. Determining hold time ensures you choose an appropriately sized box and the right PCM combination.
2. Estimate Transit Duration and Environmental Conditions
Consider the distance, potential delays and external temperatures. Passive VIP containers are ideal for moderate durations up to one week. For longer routes or extreme conditions, consider hybrid or active systems that integrate refrigeration with VIP insulation.
3. Match PCM Type to Your Temperature Band
Phase change materials play a critical role in pack out optimization. Choose PCMs with melting points aligned to your product’s temperature band. For example:
+2 °C to +8 °C: Water based gel packs or PCM gels for vaccines.
–18 °C: Ice bricks or PCMs with a melting point around –20 °C for frozen foods.
–70 °C: Dry ice or specialized PCMs for ultra cold biologics.
Proper PCM selection ensures stable internal temperatures and reduces the quantity of refrigerant needed.
4. Calculate Box Size and Payload Ratio
Thinner VIP walls increase usable space. Calculate the internal volume required for both the product and coolant. Avoid oversizing; extra air space increases thermal load and shortens hold time. A comparison from the Tempk guide shows that a VIP box of the same external size as a 20 mm EPS cooler needs only 1.5 kg of PCMs instead of 4 kg and still extends hold time. This optimization directly improves payload efficiency.
5. Protect Against Punctures
Due to fragility, always enclose VIP panels within a durable casing like EPP, corrugated plastic or fiberboard. Protective inserts and foam padding prevent impact damage during handling or transportation.
6. Plan Return and Reuse Logistics
Reusable VIP containers can deliver cost savings and sustainability benefits. Analysts predict that the reusable cold chain packaging market will grow from USD 4.97 billion in 2025 to USD 9.13 billion by 2034, with VIP containers forming a key segment. Establish reverse logistics to recover, clean and requalify containers after each use. A closed loop system reduces waste and decreases total cost of ownership.
7. Implement Real Time Monitoring
Integrate temperature sensors and data loggers into your VIP containers. Smart packaging can transmit live temperature and location data, and automatically issue alerts if temperatures deviate from set thresholds. This allows corrective action mid transit, reducing risk of spoilage.

Selecting the Right VIP Container
Choosing the ideal VIP container involves balancing performance requirements, cost and sustainability.
Assess Temperature and Duration Needs
Pharmaceuticals (2–8 °C): Choose containers validated for the vaccine or biologic hold time (72–144 h). Products like the SU96 VIP system combine VIP panels with PCM gels to maintain 2–8 °C for up to 144 hours, and are reusable for 50 cycles, reducing packaging and refrigerant weight by up to 50 %.
Ultra cold shipments (<–60 °C): VIP containers integrated with dry ice maintain temperatures below –60 °C for extended periods. For example, the Crēdo Cube Dry Ice container uses VIP insulation to keep payloads below –60 °C while reducing dry ice usage by 75 %. The container has a 5 year lifespan and payload sizes between 3 L and 96 L.
Multi temperature loads: New multi zone containers use VIP walls to separate compartments with different temperatures, enabling mixed shipments like frozen seafood and fresh produce.
Evaluate Box Size and Payload Ratio
Select a container size that fits your payload with minimal empty space. Many commercial VIP systems come in standard payload sizes—5 L, 8 L, 14 L, 16 L, 35 L and 56 L—capable of maintaining various temperature ranges for 96 h, 120 h or 240 h. Choosing the right size avoids thermal load due to excess air, which can shorten hold time.
Consider Reusability and Cleaning Protocols
Reusable VIP containers can be requalified for 50–100 cycles depending on design and cleaning protocols. Evaluate the durability of outer shells and whether your logistics network can support return and refurbishment. Some suppliers offer cleaning and requalification services to ensure performance after each cycle.
Weigh Cost Against Performance
VIP containers cost more upfront, but savings come from reduced product loss, lower shipping weight, and longer hold times. Conduct a total cost of ownership analysis that includes container purchase, reuse cycles, reverse logistics and potential savings from avoiding temperature excursions.
Factor Sustainability and Regulatory Compliance
Sustainability: Seek containers with recyclable panels or plant based PCMs. Circular economy initiatives, such as recycling VIP cores, reduce ecological impact by up to 95 %. Additionally, the global reusable cold chain packaging market is projected to grow, reflecting a shift toward sustainable, circular solutions.
Regulatory Compliance: Adhere to guidelines such as WHO’s Good Distribution Practices for pharmaceuticals, the FDA’s Food Safety Modernization Act for food, and ISTA 7E test protocols for package validation.
