How Can Packaging Manufacturers Reduce Changeover Time and Setup Waste?

Packaging manufacturers can reduce changeover time and setup waste by measuring the time and make-ready material lost on every job change, comparing changeovers across jobs, machines, and operators, and standardising the most efficient practices. Changeover loss is the capacity and material consumed switching between jobs — make-ready time when a machine produces nothing, and the substrate run as set-up waste before good product begins — and because packaging plants run many jobs a day, it is one of the largest hidden costs in the business.

This matters because packaging operates on thin margins with frequent job changes, so cumulative changeover loss has a large effect on both capacity and material cost.

Why changeover is so costly in packaging

Packaging plants run many short, high-volume jobs, so changeovers are constant. Each costs twice: the machine produces no saleable product during make-ready (lost capacity), and substrate is run to achieve registration, colour, and quality before good product comes off (make-ready waste). Across hundreds of jobs a month, these add up to a major loss of both capacity and material — but because each individual changeover looks normal and necessary, the cumulative cost is rarely measured.

What to measure

Changeover time — non-producing time per job change, by job, machine, and operator.

Make-ready waste — substrate consumed before good product begins.

Cumulative totals — the full changeover time and waste across all jobs over a period.

Variation — how changeovers differ between jobs, machines, and operators.

The variation is the most useful data: it shows that faster, lower-waste changeovers are achievable and where to improve.

How to reduce changeover loss

Standardise set-up — apply the methods of the fastest, lowest-waste changeovers across all operators.

Address problem machines — fix equipment whose changeovers consistently waste more.

Sequence jobs — order work to minimise substrate and tooling changes between jobs.

Reduce make-ready waste — target the jobs consuming the most set-up material.

How it is done effectively

To reduce changeover loss, a packaging manufacturer connects machine, production, and material data so changeover time and make-ready waste are measured, totalled, and compared across the plant. This is the kind of capability a CEO intelligence layer provides: turning scattered, accepted-as-normal changeover events into a visible, comparable cost.

Reducing changeover loss this way recovers machine capacity without new equipment, cuts make-ready material waste, and protects margin on a business that runs too thin to leave either on the floor.
