Manufacturers such as Sicom in Italy produce 20ft, 30ft, and 40ft bulk carrier containers and describe their units as specifically developed for intermodal use. Sicom’s production is based in Italy and the company emphasizes customized intermodal solutions for European transport operators.

The liner system transforms the container into a clean internal cargo space that can be used for powders, granulates, food ingredients, minerals, and chemical products.
Italian liner manufacturer Eceplast produces bulk liners for 20ft, 30ft, and 45ft containers and identifies chemical, food, and mineral applications as key use cases. The company also notes that bulk liners are commonly used by intermodal logistics operators and can replace tank trailer solutions in appropriate applications.

This makes 30ft liner containers particularly suitable for industries that require:
The liner concept also helps separate the cargo from the previous load history of the container, which is especially important for sensitive dry bulk materials.
Intermodaltrasporti describes polyethylene liners as suitable for both food and non-food bulk cargoes and specifically mentions flour, sugar, and cereals among typical food applications.

For polymer and chemical logistics, liners are also widely used to reduce the risk of contamination and to support bulk unloading systems.
Nordic Bulkers’ system can include:
Nordic Bulkers describes its 30ft containers as optimized for payload and stability and suitable for intermodal transport of sensitive and high-volume bulk materials.

The 30ft format is particularly relevant in Europe because it combines a high payload with compatibility across road, rail, and terminal handling systems.
Intermodal systems benefit from the fact that the goods themselves do not need to be physically transferred when switching transport modes. This reduces handling and helps protect product quality.

Relevant controls can include:
Nordic Bulkers highlights sealed, moisture-protected liner systems and dust-controlled unloading as part of its approach to safe intermodal bulk transport.

From a container construction perspective, European manufacturers such as Sicom also emphasize quality control, international classification standards, and specialized engineering for custom intermodal equipment.

The liner itself acts as a protective inner packaging. Intermodaltrasporti notes that polyethylene liners help preserve product integrity and prevent contamination from foreign material during bulk transport.

Another important benefit is fleet flexibility. A standardized bulk container can be integrated into intermodal transport chains and repositioned independently of a tractor unit, unlike a conventional road-only silo trailer.
UNECE states that the majority of bulk containers in Europe are 30ft long. The format is well suited to European road and rail transport because it offers a good balance between payload, volume, and intermodal handling.

The liner creates a protective barrier between the cargo and the container walls. It helps protect the product against contamination, moisture, residues from previous cargoes, dust, and foreign material. Liner bags are commonly produced from polyethylene and are designed specifically for bulk loading and unloading.
A silo truck is normally tied to road transport, while a 30ft bulk container can be transferred between truck, train, and vessel. This provides greater intermodal flexibility and allows long-distance transport to be performed by rail or short-sea shipping while road transport is used mainly for first and last mile. The liner also provides a dedicated protective cargo environment without requiring the entire transport unit to be permanently dedicated to one product.
This article is based on publicly available information from UNECE, European intermodal logistics providers, container manufacturers, liner manufacturers, and Nordic Bulkers. Nordic Bulkers specializes in intermodal dry bulk logistics using 30ft bulk containers, liner systems, road, rail, short-sea transport, and terminal services across Europe.
