Key takeaways
- Commission on new or 1A, then measure actual loads, stack heights and trips before substituting anything.
- Substitute one flow at a time, starting with the least visible — internal movement or scrap collection.
- The valid objection is consistency; the answer is single-source lots from one manufacturer and one previous user.
- Two capital items repay themselves quickly: dry roofed storage for empties and a pallet pool that measures true.
A commissioning team has a hundred things that could go wrong and no history to lean on. Packaging is not where they want a variable, so they buy new — and then, eighteen months later, somebody in procurement discovers that the boxes cost twice what they needed to.
There is a middle path, and it is mostly about sequencing.
Phase one: commission on new or 1A
During commissioning, buy new or grade 1A. Not because used stock would fail, but because during start-up you want every variable that can be eliminated to be eliminated. If a line jams, nobody should be able to point at the box.
This phase is usually six to twelve weeks and a small fraction of lifetime packaging spend.
Phase two: establish the real duty
Once the line is stable, measure three things that nobody can tell you in advance:
- Actual loaded weight per container, not the design figure.
- Actual stack height and storage duration in your building.
- Effective trips — mark fifty boxes and count them weekly for twelve weeks.
Those three numbers convert a guess into a specification, and they almost always show that the commissioning spec was conservative.
Phase three: substitute one flow at a time
Not the whole plant. Pick the least visible flow — internal movement between departments, or scrap and regrind collection — and run graded 3A there for a quarter.
| Phase | Flow | Grade | Risk | Typical saving |
|---|---|---|---|---|
| 1 | Everything, during commissioning | New / 1A | None | — |
| 2 | Internal movement, WIP | 3A | Very low | 55 – 60% vs new |
| 3 | Scrap and regrind collection | 3A – 4A | Very low | 60 – 70% vs new |
| 4 | Inbound component handling | 2A – 3A | Low | 50 – 60% vs new |
| 5 | Outbound to trade customers | 2A | Moderate — cosmetics visible | 45 – 52% vs new |
| Never | Customer-facing, printed, food contact | New | — | — |
The objection that is actually valid
Consistency. New boxes arrive identical every time. Used stock varies within a grade, and for an automated line with tight tolerances that variation can matter — particularly on box height, where a half-inch difference can affect a fill head or a conveyor transfer.
Where this is a genuine constraint, we hold single-source lots for a customer: boxes from one original manufacturer, one production run, one previous user. It costs more than general graded stock and less than new, and it is the specific answer to the consistency objection rather than a way around it.
What to put in the capital plan
Two things that cost almost nothing and repay themselves quickly: dry, roofed storage for empty containers, and a correctly sized pallet pool that actually measures 48 × 40. Plants that skip both spend the next decade destroying containers faster than necessary, whatever they buy.
