Designing an Efficient End-of-Line Packaging Layout

End-of-line layout is one of those decisions that sets the ceiling on how efficient your operation can be. Get the layout right and the equipment runs at rated speed, operators handle minimum cartons, and dispatch closes on time. Get it wrong and you spend years working around a flow that wasn't designed for the volume it's now carrying.

The trap is that most end-of-line layouts evolved rather than being designed. Something gets added when volume grows, something else gets squeezed in when a new product line launches, and what started as a clean flow becomes a tangle of operator paths and forklift movements. The result is a layout that handles 70% of its theoretical throughput, with the missing 30% lost to operator transport time and bottleneck queues.

This article walks through the principles of designing an end-of-line layout from first principles, the layout patterns that work for different volume profiles, and the common mistakes that erode efficiency. The aim is a layout you can defend on a flow diagram, not one that just happened to evolve.

Start With Volume and Flow Direction

Layout design starts with two questions: what's the daily volume, and what's the dominant flow direction? Volume determines the equipment grade and the number of stations. Flow direction determines the layout pattern.

For most Australian warehouses, the dominant flow is from picking through packing through dispatch. The end-of-line layout should support that flow without forcing cartons or pallets to backtrack. Backtracking is the silent killer of throughput; every metre a carton moves backwards is a metre it has to move forward again, with operator or forklift time attached.

Map the flow before you place equipment. Sketch where cartons enter the end-of-line zone (from pick, from manufacturing, from receiving) and where they exit (to dispatch, to staging, to specific carrier doors). The equipment placement falls out of that flow naturally if you've drawn it correctly.

The Three Layout Patterns That Work

Most efficient end-of-line layouts follow one of three patterns. The U-shape works for moderate-volume operations with a single entry and exit point. Erecting at the entry of the U, packing along the bottom, sealing and wrapping at the exit. Operators can see the whole flow and supervisory attention is consolidated.

The straight-through linear layout works for high-volume operations with conveyorised flow. Erector at one end, packing stations along the conveyor, carton sealers and pallet wrapping machines at the other end. Operators stay at their stations and the flow runs through them. Throughput is highest with this pattern but floor space requirements are significant.

The hub-and-spoke layout works for operations with multiple input flows feeding a central pack zone. Different SKU groups arrive at different points on the perimeter, all flow into the central pack and seal area, then dispatch out to multiple staging zones. This pattern handles complex SKU mixes well but needs careful management to prevent congestion at the central zone.

Pick the pattern that suits your dominant flow. Don't force a layout pattern that doesn't fit; the operational pain of fighting against it for years far outweighs the cost of designing it right at the start.

Workstation Design and Operator Ergonomics

Within the layout pattern, workstation design matters. Each pack station should have everything the operator needs within arm's reach: cartons (incoming from the erector), packing materials, labels, and tape. Anything that requires the operator to walk away from the station drops throughput by 10 to 20%.

Workstation height matters too. Most pack stations should sit at 900 to 950mm from the floor, which is comfortable for the average operator without excessive bending or reaching. Stations that are too low cause back strain over a shift; stations that are too high cause shoulder strain. WorkCover claims from packing roles correlate strongly with workstation ergonomics.

Lighting and visibility also affect throughput. Pack stations need clear overhead lighting (not glare-producing) and clear sight lines to the supervisor and to other operators. Dark or visually isolated stations slow down because the operator can't see what's coming or signal for help.

Equipment Placement and Buffer Sizing

Where the equipment sits within the layout determines whether the line runs smoothly or in starts and stops. The principle is simple: equipment goes where the work flows, not where there happened to be space.

Carton erectors sit at the start of the pack flow because they feed the pack stations. The output of the erector should land within 2 metres of the pack stations, ideally on a powered conveyor or short gravity roll that holds 4 to 6 cartons of buffer. This buffer absorbs cycle time variation between erector and packers.

Carton sealers sit at the end of the pack flow because they receive packed cartons. The input to the sealer should accumulate enough buffer (8 to 12 cartons) to handle short pauses in packing without starving the sealer or forcing operators to wait. The output of the sealer feeds the wrapping or palletising step.

Pallet wrapping equipment sits where the dispatch flow naturally consolidates. For most operations, that's near the loading dock with conveyor or forklift connection from the seal output. Don't put the wrapper near the pack stations and force forklifts through the pack zone; you'll create congestion that slows everything down.

Common Layout Mistakes to Avoid

The most common layout mistake is not allowing for forklift traffic. Forklifts need clear paths between input and output zones, and those paths shouldn't cross operator walking routes or pack station fronts. Designate forklift lanes with floor marking and keep them clear.

The second common mistake is undersizing the dispatch staging area. Packed and wrapped pallets need somewhere to wait until the truck arrives. Most operations underestimate the staging space needed and end up with pallets blocking pack stations or aisles when dispatch backs up.

The third common mistake is no provision for changeover or peak operations. Layout designed for the average flow can't handle peaks, and the operator workarounds during peaks become permanent dysfunctions over time. Design for 130% of average volume so the layout flexes without the operators having to break the flow rules.

Scaling the Layout as Volume Grows

The right layout designs in capacity for growth from the start. If you're shipping 80 pallets a day now and projecting 150 in three years, the layout should accommodate the 150 with minor additions rather than a major redesign. This usually means more buffer space, more pack station positions, and more conveyor capacity than you currently need.

Modular equipment helps here. Conveyor sections that can be added without re-engineering the whole flow. Packaging machines with capacity headroom for higher throughput. Workstations that can be reconfigured as the SKU mix changes. The capital cost of modularity is often small compared with the cost of replacing the whole layout when volume grows.

Document the layout and the rationale. The team that operates the line in three years isn't necessarily the team that designed it. A clear layout drawing with notes on why each piece sits where it does protects against well-intentioned but disruptive changes by future operators.

Why Choose Emmoco for End-of-Line Layout Design

Emmoco supplies the full range of end-of-line equipment and we offer layout design services as part of any significant equipment project.
