What is a Container Liner?

Container Liners could be considered the largest Big Bags in existence, with a potential capacity of almost 25,000 liters for 20-foot containers, and almost 50,000 liters for 40-foot containers.

In fact, as its name suggests, it is a cover or inner liner for containers, truck boxes or even train wagons, in order to load dry bulk products directly and completely into them. In this way, maximum use is made of space (maximum profitability) and at the same time ensuring that the product does not come into contact with the walls of the container, thus avoiding possible contamination and transfers (maximum safety).

Container Liners are the most economical option for transporting large quantities of non-liquid products that can be loaded and unloaded in bulk, including food products such as wheat, malt, starch, rice, coffee, pulses, sugar, seeds and other non-food products such as coal, chemicals, fertilizers or cement.

There are different types of Container Liners according to their material, configuration or arrangement of their elements.

Benefits of Container Liners

  • More ecological: To load a container with traditional Big Bags, between 20 and 40 Big bags are needed depending on the container and the load. In contrast, a single Container Liner can complete the load of a container. Thus, much less plastic material is used to cover and contain the cargo, considerably reducing the CO2 footprint in its manufacture and use compared to other alternatives.
  • Cost-effectiveness in transportation: The cost of a single Container Liner is much lower than the 20 or 40 Big Bags needed to complete a container. The load in a Container Liner is maximized, since there are no empty spaces created by Big Bags organized inside containers. Both things favor maximum profitability and optimization of the transportation of these products.
  • Quick installation: The installation of a Container Liner should not take more than 10 to 15 minutes. All containers incorporate standard fastening elements that facilitate the fastening of these container liners.
  • Best for bulk loading and unloading: It is much faster and more efficient to install a Container Liner and then load it by side telescoping tie or by vertical gravity all its contents, than to load 20 or 40 Big Bags one by one and then place them neatly inside the container.
  • Eliminates the risk of product loss and damage: Handling 20 or 40 individual Big Bags increases the risk of chafing between them or falls that could cause breakage and spillage of the material to be transported.
  • Recycled and recyclable: Currently and depending on the material to be contained, Container Liners can be built with partially recycled raw materials and are also 100% recyclable after use, thus promoting the circular economy.

Container Liners implementation projects

The acquisition of Container Liner usually arises from the need to improve and optimize costs in the transport of large quantities of product in periodic shipments of containers, as well as loading and unloading operations. Due to their special characteristics, Container Liners are always customized and made on demand. In many cases, several tests and prototypes are necessary to find the most suitable solution. In addition to supplying the different types of Container Liner, Multisac can also help in the training for its installation.
