ISO 9001:2026 · Packaging and converting
ISO 9001 for packaging converters
Colour drift, the wrong artwork, failing seals, out-of-square cartons, complaints nobody closed. None of it is a food safety issue, so none of it is covered by your packaging certificate. Here is which clause answers each one.
The short answer
Almost every complaint a packaging converter receives is a quality complaint, not a food safety one. Colour drift, registration, seal strength, dimension, the wrong artwork version, short delivery. None of those makes anyone ill, so none of them is covered by BRCGS Packaging Materials or FSSC 22000, and all of them lose listings.
ISO 9001:2026 is the standard that answers them. For a converter the work concentrates in four places: written acceptance criteria under clause 8.1, artwork and version control at the line under 8.5.1, measurement capability under 7.1.5, and the new opportunity register under 6.1.3.
The gap your packaging certificate leaves
BRCGS Packaging Materials and FSSC 22000 in category I both do a serious job on product safety and legality: migration, contamination, hygiene, traceability, defence. They are built around whether the material is safe to contact food.
What they are not built around is whether the pack you shipped matched what the brand owner ordered, or arrived when you said it would. FSSC reaches into quality at exactly two points. Additional Requirement 2.5.9 on quality control, which requires a quality policy, quality objectives and quality control parameters, and Additional Requirement 2.5.13 on product design and development for category I. Useful, and genuinely a head start. But neither requires customer satisfaction measurement, an opportunity register, the eight-item analysis at 9.1.3, or the eight-input management review at 9.3.
Your food safety certificate proves the laminate is safe. It says nothing about the fact that 4 800 units went out in last season’s sleeve.
Six converter complaints, mapped to clauses
These are the six we see most often in flexible and folding carton operations, and the clause each one lands on.
| The complaint | Root cause we usually find | Clause |
|---|---|---|
| “The colour has drifted across the run.” | Approval is a visual match at the press against an ageing proof, with no numeric tolerance and no measurement. Every operator judges slightly differently, and night shift differs most | 8.1 acceptance criteria in writing · 7.1.5 monitoring and measuring resources |
| “You shipped the old artwork.” | The current proof exists, in the studio. The version at the press is whatever was there last time. No check at changeover ties the job number to the artwork revision | 8.5.1 availability of documented information defining characteristics · 7.5 control of documented information |
| “Seals are failing on the filling line.” | Seal strength is specified by the customer but tested only at set-up, not through the run, and the test method is not written down so two technicians run it differently | 8.1 acceptance criteria · 8.5.1 monitoring through the run · 7.1.5 method and equipment |
| “Cartons are out of square / dimensions are off.” | Tooling wear is real but there is no link between tooling condition and dimensional tolerance, and no trigger for taking a tool out of service | 7.1.3 infrastructure · 8.5.1 controlled conditions |
| “We logged a complaint three weeks ago.” | Complaints go to the person who took the call. There is no register, no owner, no due date, and nothing feeds back into the system | 10.2 nonconformity and corrective action · 9.1.2 customer satisfaction |
| “OTIF has been under 80% for two quarters.” | Delivery performance is measured by despatch and discussed nowhere. It is not a quality objective and it does not appear in management review | 6.2 quality objectives · 9.1.3 analysis · 9.3 management review |
The toolkit is written for exactly this operation. Part 2 is ten packaging quality control modules: artwork, print and colour; converting; laboratory and test methods; SPC and capability; measurement system analysis; customer specific requirements; identification, labelling and packing; warehousing and dispatch; equipment, tooling and maintenance; and cost of poor quality. A generic ISO 9001 toolkit gives you clauses 4 to 10 and stops.
Acceptance criteria: the 8.1 problem
Clause 8.1 in the 2026 edition is restructured a) to e) and it now separates process criteria from acceptance criteria explicitly. For a converter this is the single most common finding, and it is rarely because the site is doing anything wrong.
The usual situation: the operator knows exactly what is acceptable. They have run the press for nine years. They will reject work a specification would pass. The problem is that the criterion lives in their head, so it cannot be audited, cannot be transferred to a new starter, and varies between shifts.
| What we usually find | What 8.1 needs |
|---|---|
| “Match to approved proof” | A numeric tolerance, a measurement geometry, and the instrument. A tolerance without the measurement conditions is not repeatable |
| “Seal must be adequate” | A value, a unit, a test method reference, a sample size and a frequency through the run |
| “No visible defects” | A defect classification with examples: critical, major, minor, and what each triggers |
| Tolerances in three places that disagree | One master specification that holds each parameter once, with everything else referencing it |
| Criteria recorded but no link to the customer’s spec | Traceability from the customer requirement under 8.2.2 through to the criterion applied at the line |
The single highest-value document for a converter. A master product and process specification that holds every parameter once. Bond strength, seal strength, coat weight, colour tolerance, ink viscosity, cure conditions, each stated in one place, with every work instruction and control form referencing it rather than restating it. This is what stops an auditor finding two different tolerances for the same seal, which is the finding that turns a smooth audit into a difficult one.
Artwork and version control
Artwork errors are the most commercially expensive quality failure in packaging, because the whole run is scrap and the brand owner’s promotion is affected. Clause 8.5.1 requires controlled conditions including the availability of documented information that defines the characteristics of the product. Artwork is that documented information.
- One controlled source, one revision number
The artwork register is the master. Every proof carries a revision. Nothing at the press is uncontrolled, including the laminated copy taped to the frame that nobody can date.
- Bind the revision to the job
The works order carries the artwork revision number. If they do not match at set-up, the job does not start. This is a one-line change to the changeover checklist and it prevents most of the failures.
- Sign off at first-off, against the proof physically present
Not against memory and not against a proof in the office. First-off approval records the revision that was in front of the operator.
- Withdraw superseded proofs actively
Clause 7.5.3 requires prevention of unintended use of obsolete documented information. On a press that means physically removing the old proof, and recording that you did.
- Make the customer’s approval traceable
Keep the customer’s written artwork approval linked to the revision. When there is a dispute about which version was agreed, this is the record that settles it.
Measurement you can defend
Clause 7.1.5.2 requires measurement traceability where it is a requirement, or where the organisation determines it is necessary for confidence in results. For a converter, three areas repay attention.
Numbers, not opinions
A spectrophotometer, a stated geometry and illuminant, and a numeric tolerance agreed per customer. Once colour is measured, “the colour is wrong” becomes a number either side of a limit, and the argument with the customer ends.
Method before value
A value means nothing without the method. Specimen width, grip separation, test speed and specimen count all change the result. Write the method into the specification. Test speed in particular is the commonest way a failing bond is made to look like a passing one.
Can the process hold it?
Before agreeing a tolerance with a customer, run a capability study. Agreeing a tolerance the press cannot hold converts a commercial win into a permanent nonconformance and a rising reject rate.
If you hold BRCGS Packaging Materials
You already own a large part of an ISO 9001 system and it should not be rebuilt. The decision is per requirement, not per standard.
| Requirement | Decision | What changes |
|---|---|---|
| Document control and records | SHARE | One procedure, one master list, one numbering convention. No change beyond naming ISO 9001 in the document |
| Internal audit programme | SHARE | One programme, combined audits. Add the 9.2.2 a) objective sentence to every plan |
| Calibration register | SHARE | One register. Add a column showing which system each instrument serves |
| Management review | EXTEND | One meeting. Rebuild the agenda to the eight ISO 9001 inputs and fold the scheme inputs in |
| Complaint handling | EXTEND | One register, with a food-safety yes/no field first. That field drives the approval route and the retention period |
| Specifications | EXTEND | Add quality acceptance criteria alongside the safety and legality parameters you already hold |
| Customer satisfaction, opportunity register, 9.1.3 analysis | NEW | No packaging scheme equivalent. This is the genuine build |
| Hygiene, pest control, foreign body, product safety | SEPARATE | Leave them exactly where they are |
A realistic first ninety days
For a converter that already holds a packaging scheme certificate and is adding ISO 9001:2026.
| Weeks | Focus | Output |
|---|---|---|
| 1 to 2 | Gap analysis against the 2026 edition, and the integration decision | A marked-up list of what you already have, what extends, and what is new |
| 3 to 5 | The master specification. Every parameter, once | One controlled document; every tolerance in the plant traced to it |
| 5 to 7 | Acceptance criteria into work instructions, artwork control at changeover | Revised WIs and a changeover checklist that binds artwork revision to works order |
| 6 to 9 | The 6.1.3 opportunity register workshop and second pass | A register with entries through all seven steps, some not pursued |
| 8 to 10 | Complaints register, customer satisfaction method, OTIF as an objective | 9.1.2 and 6.2 evidence beginning to accumulate |
| 10 to 12 | Internal audit to the 2026 checklist, then management review to eight inputs | Findings, actions, and a review with decisions and resources recorded |
| After | Run it for a quarter before the audit | A history the auditor can sample. This is the part sites skip and regret |
Three ways to do this, and most sites use two. The toolkit removes the authoring. The courses build the competence the auditor will interview. Consulting covers the gap analysis, the opportunity workshop and the mock stage 2, the parts that need someone on your floor.
Questions people ask
We hold BRCGS Packaging Materials. Does a customer asking for ISO 9001 mean we need both?
Usually yes, because they answer different questions. BRCGS Packaging Materials covers product safety, legality and quality of the material itself; ISO 9001 covers whether you consistently deliver what the customer agreed, including artwork, delivery and complaint handling. They are separate certificates from separate audits. But you need one management system, not two, most of clauses 4, 5, 7, 9 and 10 can be built once and audited twice.
What is the biggest ISO 9001 finding for a converter?
Acceptance criteria that exist only in the operator’s head. Clause 8.1 in the 2026 edition separates process criteria from acceptance criteria and expects both in writing. Sites lose findings here despite making good product, because the auditor asks the operator what the tolerance is, gets a correct answer, then asks to see it in a controlled document and cannot.
Do we need a spectrophotometer to pass?
No. Nothing in ISO 9001 requires a specific instrument. What clause 8.1 requires is an acceptance criterion, and clause 7.1.5 requires that whatever you use to judge conformity is suitable and, where necessary, traceable. A documented visual standard with a controlled reference, a defined viewing condition and a defect classification can satisfy the clause. Measurement makes colour disputes shorter, which is a commercial argument rather than a certification one.
How long does ISO 9001 certification take for a converter?
If you already hold a packaging scheme certificate, allow four to six months to build and a further quarter running the system before the audit, then the certification body’s own scheduling on top. From nothing, six to twelve months for the system and nine to fifteen months to the certificate in hand. The constraint is rarely the documentation; it is generating enough records for the auditor to sample. See our breakdown of what certification costs in South Africa.
Is the toolkit only for flexible packaging?
It is written around a converting operation with a flexible laminate line and a folding carton line, because that covers the widest range of converting processes: print, lamination, curing, die-cutting, gluing and finishing. Labels, rigid containers and corrugated sites use the same Part 1 and Part 3 without change, and adapt Part 2, the process steps differ but artwork control, colour, dimensional control, tooling and SPC do not.
