Warehouse Layout Design for End-of-Line Packaging | Emmoco
End-of-line layout sets the ceiling on how efficient your operation can be. Get it right and 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 was never designed for the volume it now carries.
The trap is that most layouts evolved rather than being designed. Something gets added when volume grows, something else gets squeezed in when a product line launches, and a clean flow becomes a tangle of operator paths and forklift movements. The result typically runs at around 70% of theoretical throughput, with the missing 30% lost to transport time and queues.
Zone the warehouse before you place equipment
Before detailed equipment placement, get the warehouse-level zoning right. Four zones and the adjacencies between them do most of the work:
- Receiving sits next to storage and picking, so inbound stock does not travel across the site before it is put away.
- Picking and packing flow directly into the end-of-line zone without crossing inbound traffic.
- Wrap and strap sits hard against the loading dock. This is the one adjacency people most often get wrong, and it costs a forklift movement on every pallet.
- Dispatch staging is sequenced in truck-load order, so the last pallet wrapped is not the first one needed.
Aisle width is a genuine trade-off, not a default. Too narrow and you get congestion and near-misses between forklifts and pedestrians. Too wide and you are paying warehouse rent for empty concrete. Size aisles for the traffic you expect in three years, not the traffic you have today.
If floor space is the binding constraint, look up before you look sideways. Vertical racking frees floor area for pack stations, and mezzanine-level staging can absorb dispatch overflow without extending the building.
Start with volume and flow direction
Layout design starts with two questions: what is the daily volume, and what is the dominant flow direction? Volume determines equipment grade and station count. Flow direction determines the layout pattern.
For most Australian warehouses the dominant flow runs picking to packing to dispatch. The layout should support that 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 placing equipment. Sketch where cartons enter the zone and where they exit. Equipment placement falls out of that flow naturally if the drawing is right.
The three layout patterns that work
U-shape suits moderate-volume operations with a single entry and exit. Erecting at the entry, packing along the bottom, sealing and wrapping at the exit. Operators can see the whole flow and supervision stays consolidated.
Straight-through linear suits high-volume conveyorised flow. Erector at one end, packing stations along the conveyor, carton sealers and pallet wrapping machines at the other. Highest throughput, but floor space requirements are significant.
Hub-and-spoke suits multiple input flows feeding a central pack zone. Different SKU groups arrive at different perimeter points, flow into a central pack and seal area, then out to multiple staging zones. Handles complex SKU mixes well but needs active management to prevent congestion at the centre.
Pick the pattern that suits your dominant flow. Fighting a pattern that does not fit costs far more over the years than designing it correctly once.
Workstation design and operator ergonomics
Each pack station should have everything the operator needs within arm's reach: cartons from the erector, packing materials, labels and tape. Anything that makes the operator walk away from the station drops throughput by 10 to 20%.
Height matters. Most pack stations should sit 900 to 950mm from the floor, comfortable for the average operator without excessive bending or reaching. Too low causes back strain across a shift, too high causes shoulder strain. WorkCover claims from packing roles correlate strongly with workstation ergonomics.
Make workstations relocatable where you can. Bolted-down benches lock in a layout that will need to change as SKU mix and volume shift. Modular stations on castors or bolt-down feet let you re-sequence a line in a weekend instead of a shutdown.
Lighting and sight lines affect throughput too. Pack stations need clear overhead lighting without glare, and clear sight lines to the supervisor and other operators. Visually isolated stations slow down because the operator cannot see what is coming or signal for help.
Equipment placement and buffer sizing
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. Erector output should land within 2 metres of the pack stations, ideally on a powered conveyor or short gravity roll holding 4 to 6 cartons of buffer. That buffer absorbs cycle time variation between erector and packers.
Carton sealers sit at the end of the pack flow. The input should accumulate 8 to 12 cartons of buffer so short pauses in packing do not starve the sealer or leave operators waiting. Sealer output feeds wrapping or palletising.
Pallet wrapping sits where dispatch flow consolidates, for most operations near the loading dock with conveyor or forklift connection from the seal output. Do not put the wrapper near the pack stations and route forklifts through the pack zone. That single decision creates congestion that slows everything downstream. Keep stretch film and strapping equipment stocked at the point of use rather than in a store room.
Zones people forget
Returns and repack. Returns handled inside the picking or storage zone contaminate stock accuracy and interrupt outbound flow. Give returns their own area with its own bench and its own consumables.
Reusable packaging. If you run crates, plastic pallets or reusable dunnage, they need a collection, cleaning and redeployment loop with dedicated space. Without it, reusables end up stacked wherever there is a gap and the reuse rate quietly collapses.
Waste segregation. Put recycling and waste bins inside the pack zone, within reach of the station. Contamination rates drop noticeably when bins sit in the workflow rather than beside it, and operators stop walking film offcuts across the floor.
Common layout mistakes to avoid
Not allowing for forklift traffic. Forklifts need clear paths between input and output zones, and those paths should not cross operator walking routes or pack station fronts. Mark forklift lanes, pedestrian walkways and hazard zones on the floor, and keep them clear. Floor marking is the cheapest safety and efficiency intervention available.
Undersizing dispatch staging. Packed and wrapped pallets need somewhere to wait for the truck. Most operations underestimate this and end up with pallets blocking pack stations or aisles when dispatch backs up.
No provision for peaks. A layout designed for average flow cannot handle peaks, and the operator workarounds invented during a peak become permanent dysfunctions. Design for 130% of average volume so the layout flexes without breaking the flow rules.
Scaling the layout as volume grows
Design in capacity for growth from the start. If you ship 80 pallets a day now and project 150 within three years, the layout should absorb the 150 with minor additions rather than a redesign. In practice that means more buffer space, more pack station positions and more conveyor capacity than you currently need.
Modularity helps: conveyor sections that extend without re-engineering the flow, packaging machines with capacity headroom, workstations that reconfigure as SKU mix changes. For the equipment side of this decision, see our guide to end-of-line packaging efficiency.
Review the layout, do not set and forget
A layout is a hypothesis about how work should flow. Test it. Track throughput per station, average pack time and material usage per pallet, and watch where the numbers drift.
Ask the operators. They know which reach is awkward and which trolley always ends up in the wrong place, and they will usually tell you if asked directly. If you are running scan data through QR or barcode at pack and dispatch, that movement data will show you the real paths people take rather than the ones on the drawing.
Run a formal layout audit periodically, and document the layout and its rationale. The team operating the line in three years is not necessarily the team that designed it. A clear drawing with notes on why each piece sits where it does protects against well-intentioned but disruptive changes.
Talking to Emmoco
Emmoco supplies the full range of end-of-line equipment and offers layout design as part of any significant equipment project. Our service techs visit the site, measure the existing space and produce CAD drawings showing equipment placement, conveyor flow and operator paths.
We also phase installation: design the full layout, deliver the immediate-need equipment first, and stage in additional capacity as volume justifies it. Our packaging machine hire program is useful for testing equipment within a proposed layout before committing to a permanent install.
