There is a well-known saying in air logistics:
“Reducing one gram of weight is worth one dollar.”
Weight means cost. SuperCooler Lightweight Vacuum Insulation Panel
This is not an exaggeration —
It is the most direct expression of weight cost in the air transportation industry.
Let us do the math.
Air freight charging logic:
Air freight is usually charged based on
actual weight or volumetric weight, which is calculated as length × width × height in centimeters ÷ 6000,
whichever is greater.
Average international air freight rates:
Air freight type | Rate |
Standard / Economy air freight | 3–8 USD/kg |
Express / dedicated cold-chain routes | 8–15 USD/kg |
Peak rates on some high-demand routes | Above 20 USD/kg |
Take a standard air cargo insulated shipper as an example:
Reference shipper specifications:
Box specification | Value |
External dimensions | 600 mm × 400 mm × 400 mm |
Insulation layer thickness | 50 mm |
Estimated insulation layer volume | 0.038 m³ |
Item | Conventional VIP core material | SuperCooler Lightweight VIP | Weight reduction |
Core material density | 180–220 kg/m³ | 42 ± 5 kg/m³ | —— |
Density used for calculation | 200 kg/m³ | 42 kg/m³ | —— |
Insulation layer weight | 200 × 0.038 = 7.6 kg | 42 × 0.038 = 1.6 kg | 6 kg |
Weight reduction per shipper: approximately 6 kg.
Route type | Rate | Saving per shipper per shipment | Saving over 100 shipments per year |
Domestic air freight | 5 USD/kg | 30 USD | 3,000 USD |
International economy air freight | 8 USD/kg | 48 USD | 4,800 USD |
Dedicated cold-chain express route | 12 USD/kg | 72 USD | 7,200 USD |
Peak high-demand route | 20 USD/kg | 120 USD | 12,000 USD |
If you use 10 shippers per shipment:
→ Under the dedicated cold-chain express scenario, annual freight savings can reach 72,000 USD.
→ Equivalent to more than RMB 500,000.
There is also a hidden cost-saving factor that many people overlook.
SuperCooler Lightweight VIP has a thermal conductivity of 0.0055–0.0065 W/(m·K).
With the same insulation performance, the shipper walls can be made thinner:
Item | Traditional design | With Lightweight VIP |
Insulation layer thickness | 50–80 mm | 35 mm |
External box dimensions | Larger | Can be reduced |
Volumetric weight/ weight | Higher | Reduced accordingly |
Freight cost | Higher | Further reduced |
Thinner walls increase internal space by 15%–25%.
→ More cargo can be loaded in the same air cargo space.
→ Freight cost per unit of cargo is further reduced.
The weight of each shipper can be reduced by more than 6 kg.
→ Loading and unloading efficiency is improved.
→ Manual handling becomes easier.
→ The risk of cargo damage caused by heavy handling is reduced.
Parameter | Value |
Core material density | 42 ± 5 kg/m³ |
Thermal conductivity | 0.0055–0.0065 W/(m·K) |
thermal conductivity of standard PU | 0.023 W/(m·K) |
thermal conductivity of EPS foam | 0.040 W/(m·K) |
Operating temperature range | -196°C to 150°C |
Internal vacuum level | < 10 Pa |
Minimum processable thickness | 10 mm |
Weight saving per shipper compared with conventional VIP | 6 kg |
Service life | More than 5 years |
In sum,
“Reducing one gram of weight is worth one dollar.”
SuperCooler Lightweight VIP can reduce the weight of each shipper by approximately 6,000 grams.
Based on dedicated cold-chain route freight rates,
each shipment can save approximately 72 USD in freight cost.
Over 100 shipments per year, the saving can reach approximately 7,200 USD.
This does not include the additional volumetric-weight savings from thinner shipper walls.
Super Tech Cold Chain · SuperCooler Lightweight VIP —
is not merely an insulation panel.
It is a freight cost-saving solution.
Ordinary lightweight insulated boxes, such as foam boxes, are inexpensive and easy to carry, but they have clear limitations in insulation performance.
For international shipments that often last dozens of hours, foam boxes cannot reliably maintain stable and controllable temperatures throughout the entire route.
A true air-grade insulated shipper must solve three key challenges at the same time: lightweight design, high thermal insulation performance, and low total cost.
SuperCooler Lightweight Vacuum Insulation Panel is designed to meet this challenge.
