First in, first out (FIFO) stock rotation is standard practice for almost every business that uses FIBCs (Flexible Intermediate Bulk Containers), or at least, it is on paper. In practice, although FIFO is a textbook process that ideally happens, it rarely dictates day-to-day handling decisions. This often means that newer bags are pulled first because they are easier to access, while older stock sits untouched in storage. Over time, this seemingly minor operational habit can create significant risk, with an impact on bulk bag safety and product quality. In this article, we explore the hidden costs of poor FIBC stock rotation, and why first in, first out matters.
What Makes Fibc Stock Rotation A Business Issue
To answer this question, it is worth revisiting the core purpose of FIFO. First in first out stock rotation ensures that materials are used within their optimal lifespan. With FIBCs and UN certified bulk bags, this is particularly important because bags are not inert products. Even when unused, they continue to be affected by their storage environment.
Older bags left in storage are exposed to several degradation factors, such as:
- UV exposure: prolonged exposure to sunlight can break down polypropylene fibres, even when UV inhibitors are present in the fabric
- Temperature fluctuations: repeated heating and cooling cycles cause the bag material to expand and contract, accelerating the rate of fatigue
- Environmental exposure: rain, damp, dirt, and airborne contaminants can degrade fabric integrity and stitching over time
When newer stock is habitually used ahead of your older bags, the oldest inventory quietly becomes the weakest link in the supply chain; a bulk bag safety issue waiting to happen.
What Are The Consequences Of A Poor Rotation System?
Failures linked to poorly stored or old FIBCs typically occur suddenly and without warning. A bag may appear visually acceptable in the warehouse but fail under load or during handling. Common issues seen in practice include:
- Torn or weakened stitching, particularly along seams that have experienced prolonged stress.
- Compromised fabric structure, reducing the bag’s safe working load limits.
- Damaged or degraded lift loops, which are especially vulnerable to UV damage and material fatigue.
There are various costs associated with these failures, and not simply the price of a replacement bag. Failures often include the loss of the contained product, cleanup and disposal costs, safety risks to staff and bystanders, and potential non-compliance with internal safety policies or industry standards. In many cases, expensive and dangerous failures can be prevented through disciplined stock rotation and inspections.
However, even with a FIFO system in place, some bags will inevitably spend longer periods in storage, so before deploying older stock, a thorough inspection protocol is essential. Key indicators to assess include any discoloration or fading, which is often a sign of UV exposure, cracking or stiffness around the lift loops, and signs of contamination or moisture ingress, such as staining and mould growth. A change to the fabric texture, such as brittleness or excessive softness, could also indicate a need for replacement; and if there is any doubt about the integrity of the bag, remember that the cost of replacement is almost always lower than the cost of failure.
How To Implement A Fifo System In Your Warehouse
First in, first out is a straightforward idea in principle, but practical barriers often get in the way of implementation. Space constraints, handling convenience, and legacy layouts can undermine the best laid plans and cause newer bags to be used first in place of older stock. FIFO is as much a matter of warehouse layout design as it is inventory management. However, effective FIFO does not usually require a complete warehouse redesign. Designating clear inbound and outbound lanes in the warehouse so that older stock is naturally accessed first can help streamline your warehouse planning so that FIFO is easier to implement. Also, many businesses use date-coded tags or colour systems to make production or delivery dates more immediately obvious to warehouse operatives.
