Dry cargo box, sometimes also called dry freight container, has become a vital part of the supply-chain infrastructure. After intermodal container transportation, cargo boxes take the tasks of last-mile delivery. Traditional cargos are usually in metal materials, however recently, a new material–composite panel–is making a figure in the production of dry cargo boxes.

TOPOLO composite sandwich panel is an ideal choice for dry cargo boxes.

The major advantages are as follow:


Continuous fiber-reinforced thermoplastic panels are much lighter than metal ones. In making cargo containers, this is the biggest advantage for freight loading.


Thermoplastic materials are 100% recyclable. They contribute more to the environment than metal materials.

High strength

Being lightweight, the composite cargo box panels are no less strong in impact resistance, even stronger than metal containers. This is because the continuous fiber in the material significantly reinforces the strength of cargo panels.

In addition to last-mile delivery, dry cargo box panels are also customizable for various applications, such as:

Small package containers (using TOPOLO 8mm to 10mm honeycomb panels or 3mm composite sheets)

Fragile product containers (for antiques and luxury car storage)

Reefer trailers and cold vans (The special thermo-property can help to keep the temperature in the containers.)

General-purpose containers

Shells of electric appliance
