Liquid and Grease on the Move...
Safeguarding cleanliness
Since the beginning of mankind there has been a need to store and transport liquids in one way or another – one of the earliest examples of logistics. Today safe storage, transportation of lubricants and logistics are synonymous.
Traditionally 200 litre drums and 1000 litre Intermediate Bulk Containers (IBC) have been used for storage and transportation of a whole range of lubricants. For greases, drums have dominated in workshops around the world.
Since the mid 1950’s there has been widespread container innovation aimed not only at safe transportation and storage, but more recently at endeavouring to take into account a gamut of environmental issues.

Contaminated lubricants, whether they be moisture or any other form, do not sit well with machinery.
Fluid-Bag’s engineers in Finland during the mid 1980s worked on designing a 1000 litre container to meet a number of perceived market needs and raised the bar for container design and performance.
• Recyclable, environmentally friendly • Single trip, one-way system • Long term storage • Preserves lubricant integrity • Complete protection from contamination
• Minimises residue
This resulted in the Fluid-Bag “Flexi” followed a few years later with the
“Multi” – a multi trip version based on either galvanised or stainless steel pallets. From a logistics perspective Fluid-Bags are shipped in containers (18000 litre), transported by road and rail.
These unique 1000 litre containers are based on plastic multi-layer foil technology. The inner container holding the liquid is therefore flexible.
How does a flexible container contribute to cleanliness and efficiency?
The flexibility allows the stretching of the inner container ensuring:
• Maximum filling level is guaranteed, leaving no air-filled space in the container avoiding moisture contamination even under the harshest climatic conditions.
• No risk of moisture ingress due to temperature variations when stored externally, as is the case with any rigid container. Inevitably pressure variations occur in rigid containers when trapped air and the content inside expands or contracts with changing ambient temperatures creating an under pressure in the container, drawing in air with resultant moisture. In addition, this phenomenon can cause rust particles to accumulate in the lubricant because of the moisture. The Fluid-Bag being flexible, stretches with the temperature variations. No under pressure is created, and no contaminant ingress. The container is made of plastic, so no metal is present.
