Packaging, warehousing and distribution are one system with three invoices. Pack dimensions decide storage density and carriage cost; storage conditions decide what the packaging has to survive; and distribution mode decides the failure modes the pack must resist. Specifying them separately is why businesses optimise one and pay for it in the other two.
Three decisions that are really one
In most businesses packaging is bought by one person, warehousing is contracted by another and distribution is negotiated by a third. Each optimises their own line, and the interactions between them go unmanaged.
They are not independent. The pack determines how much product fits in a pallet position and how much a carrier charges; the storage conditions determine what the board has to withstand; and the transport mode determines whether the dominant failure is movement, compression or moisture.
How packaging drives storage cost
Storage is sold by the pallet position or by the square foot. The number of units that fit into one is a packaging outcome.
- Case dimensions that divide into the pallet footprint fill the deck; ones that do not waste it.
- Case height that divides into the stack limit fills the cube; one that does not leaves air at the top.
- Board strong enough to stack high lets you use the height; board that is not forces shorter stacks and more positions.
- Packaging materials themselves occupy positions - bulky, low value per cubic metre, and frequently stored at product rates.
See warehouse storage and pallet storage.
How storage drives packaging requirements
The relationship runs both ways. Long dwell in a building that is not climate controlled means board loses compression strength over time, which has to be designed in rather than discovered.
| Condition | Packaging consequence |
|---|---|
| Long dwell | Board grade allowing for strength loss over time |
| High humidity | Higher grade or moisture barrier; corrosion protection for metals |
| Tall racking | Stack-load specification and corner protection |
| Frequent handling or re-picking | Cases that survive being opened and re-stacked |
| Temperature variation | Adhesive and film performance checked at both extremes |
Storage conditions and their packaging consequence.
How distribution mode drives the pack
The same product needs different packaging depending on how it leaves.
- Parcel network: rough, frequent handling. Restraint and closure dominate - see postal and parcel packaging.
- Pallet distribution: gentle handling, heavy stack load. Board grade and build quality dominate - see transport and distribution.
- Retail delivery: the case has to work in a backroom and on a shelf - see retail packaging.
- International: long dwell, humidity, multiple handling regimes - see export packing.
The chain WSUK actually runs
Storage, packaging, fulfilment, pick and pack, parcel despatch, delivery and returns. Packaging is the step most businesses buy from somebody with no connection to the rest of it, which is exactly why it so often does not fit.
When the same operation holds the stock, specifies the pack and despatches the order, the specification can be written from the pack bench outward and tested against the carriers actually used. See packaging services and packaging for fulfilment.
What to look at if you want the system view
- Units per pallet position, and whether case dimensions are the constraint.
- Packaging materials occupying storage, and at what rate.
- Carriage band per pack format.
- Damage by failure mode, split between storage, handling and transit.
- Pack time per order.
- Whether the same specification document exists in all three places.
That last point is the one that most often reveals the problem: three functions working from three different understandings of what the pack is supposed to do.
Sequencing a joined-up review
Start from distribution, because it is the least flexible - carrier bands and modes are externally set. Specify the pack to suit them, then configure storage around the resulting case dimensions.
Doing it in that order avoids the common outcome of a storage-optimised case that is expensive to ship. A packaging review covers all three.
The short version
- Three functions, three invoices, one system.
- Pack dimensions decide storage density and carriage cost.
- Storage conditions decide what the packaging has to survive.
- Start from distribution constraints - they are externally set.
- The usual problem is three functions working to three different understandings.
Frequently asked questions
Should packaging be specified before or after choosing a 3PL?
Before, ideally, so the specification travels with the stock. If it is already outsourced, write it down and agree it rather than inheriting the provider's habits.
How does packaging affect storage cost?
Through units per pallet position and stack height - both of which are packaging outcomes. Packaging materials also occupy positions themselves.
Which should we optimise first?
Distribution constraints, because carrier bands and transport modes are externally set. Then specify the pack, then configure storage around it.
Can one provider handle all three?
Yes - WSUK provides warehouse storage, packaging and transport and distribution, which is what allows the specification to be written once and applied consistently.
What is the first sign these are not joined up?
Three functions with three different ideas of what the pack is for - typically visible as a storage-efficient case that attracts carriage surcharges, or a parcel-optimised pack that crushes in a stack.
