A converter printing reel fed laminate books its first FSSC 22000 audit and buys a consultancy package built for a food factory. It arrives with a zoning plan, a cook step validation template and a swabbing schedule. Some of it is useful. None of it is the document the auditor will actually open first, and nothing in it mentions set-off, migration or snap-off knives.
In short
- Food and feed packaging manufacture sits in food chain category I. A category I FSSC 22000 Version 7 audit is conducted against four documents, not one.
- Those four are ISO 22000:2018, ISO 22002-100:2025, ISO 22002-4:2025 and the FSSC 22000 Version 7 additional requirements.
- ISO 22002-4 is the packaging prerequisite specification. It sits on top of ISO 22002-100 rather than replacing it, and it carries requirements that exist nowhere else in the family: set-off, migration, sharps and rework usage.
- Category I is the only food chain category the scheme excludes from 2.5.16, food loss and waste. It is also inside 2.5.7 environmental monitoring and inside 2.5.11 a) on functional packaging, both of which catch converters out.
- The FSSC 22000 Version 7 for Food and Feed Packaging Manufacturing course (R2 950) teaches the two documents specific to category I. The Packaging Pathway Bundle takes all three courses to R4 950.
The four documents, and why the split matters
FSSC 22000 is a scheme rather than a standard. It binds existing standards together and adds requirements of its own, and for category I the set is fixed. ISO 22000:2018 gives you the management system: hazard analysis, the plan-do-check-act structure, and what an auditor looks for. ISO 22002-100:2025 gives you the prerequisite programmes shared by the whole food, feed and packaging supply chain. ISO 22002-4:2025 gives you the packaging layer on top of those shared programmes. The FSSC 22000 additional requirements then apply according to a category table.
The habit worth building is to ask, of any requirement, which of the four it came from. Teams that can answer with the clause reference attached run visibly shorter audits. Teams that treat it as one undifferentiated pile of rules rebuild their evidence at every surveillance visit.
What ISO 22002-4:2025 adds that no other part does
Set-off, at section 12.2. The standard defines set-off as the transfer of substances from one surface of a material to the food contact surface through direct contact caused by stacking or reeling. If you print or coat, this is your clause. The control level required is the one your hazard analysis defines, which means you have to have done the analysis rather than adopted a house rule.
Migration, at section 12.4. Controls are required where there is a potential food safety hazard from migration or another transfer mechanism. The clause then reaches further than converters expect: packaging used around your product, meaning pallets, films and containers, shall be made of suitable material, shall be clean, and shall not contaminate the food packaging you are producing. A note observes that chemical treatment of pallets can be necessary to meet regulatory or customer requirements, which is not the same as a requirement to treat them.
Sharps, at section 12.3. A formal procedure for the use of sharps is required, no sharp objects or loose tools may be left where product contamination can occur, and the use of snap-off blade knives is forbidden. Not discouraged, not risk assessed. Forbidden. It is the single quickest finding to pick up on a walk through a converting hall, and the single easiest to close before the auditor arrives.
Rework usage, at section 17. The acceptable quantity, type and conditions of rework use must be specified and the method of addition defined, measures must prevent contamination with materials not intended for food contact, and documented information must be retained to demonstrate that conformance to regulatory and customer requirements is maintained. Rework coming back from the same customer order creates no exemption.
Purchased materials, at section 10. Where incoming raw materials come from a recycled source, are nano materials or are plant-based, measures must verify that food safety and traceability requirements have been met before acceptance. Where tamper-evident seals are used, a verification process must confirm conformance to customer or regulatory requirements. Access points to bulk raw material receiving lines must be identified and, if appropriate, capped and secured. Recycled sources are controlled rather than prohibited, which is worth saying plainly to a sales team.
Which additional requirements reach category I
Most of the eighteen reach you through an all-category scope, and three deserve naming because converters get them wrong in both directions.
2.5.7 environmental monitoring applies to you. It is scoped to BIII, C, I and K, and category I appears. Packaging manufacturers sometimes assume a swabbing programme is a food factory concern. It is not: you carry the risk based environmental monitoring programme, the documented procedure for evaluating control effectiveness, the review triggers and the trend analysis.
2.5.11 a) on functional packaging applies to you. Where packaging is used to impart or provide a functional effect on food, such as shelf life extension, specific requirements must be in place. If you make a modified atmosphere film, an oxygen scavenging liner or an antimicrobial coating, that clause is written for you.
2.5.16 food loss and waste does not apply to you. It applies to all food chain categories excluding I, and category I is the only one excluded. Write it into your applicability table as not applicable with the scope quoted, and redirect the effort somewhere it will be tested.
Two others worth marking: 2.5.13 product design and development names I, and item g) is written for organizations that design primary packaging, so it lands squarely on your development function. 2.5.18 multi-site certification does not name I, so a converter group with several plants is outside it.
The order to learn this in
The packaging course deliberately teaches only the two documents that are specific to category I. It assumes you already hold the other two. That is the design rather than a gap: re-teaching hazard analysis and the shared prerequisite programmes inside a sector course produces a long, expensive course that repeats what you can learn better on its own.
So the pathway runs in three steps, and the system enforces it. First The ISO 22000 Standard, the management system itself. Then ISO 22002-100:2025, the shared prerequisite programmes. Then the packaging layer. The sector course stays locked until the first two show as complete in your dashboard, at which point it opens on its own.
Taken separately the three come to R5 900. The Packaging Pathway Bundle is R4 950, and you still earn a separate certificate for each of the three courses.
Common questions
Is a packaging converter category I or category C?
Category I, where you manufacture food or feed packaging material. A site that also fills or packs food for a customer is doing something else as well, and that is a second scope the certificate has to state.
Does ISO 22002-4:2025 replace ISO 22002-100:2025?
No. ISO 22002-100 holds the requirements common to the whole supply chain and ISO 22002-4 adds the packaging layer on top. You are audited against both, and an auditor will move between them without announcing it.
Do packaging manufacturers need an environmental monitoring programme?
Yes. Clause 2.5.7 names BIII, C, I and K, so category I is inside it. This is the opposite of the position in catering, transport and storage, feed and retail, where 2.5.7 does not reach the category at all.
Are snap-off blade knives really banned?
Yes. Section 12.3 of ISO 22002-4:2025 states that their use shall be forbidden, alongside a formal sharps procedure and a rule that no sharp objects or loose tools are left where product contamination can occur.
Is the certificate verifiable?
Yes. Every ASC certificate carries a unique certificate number and a QR code that resolves to a verification page on this site showing the learner name, course and completion date, so an auditor or employer can confirm it against our records rather than the document in front of them.
