The food safety certifications most relevant to thermoformed packaging include FDA compliance (for the US market), EU Regulation 10/2011 (for the European market), ISO 22000, and FSSC 22000, alongside GFSI-recognised schemes such as BRC Packaging and IFS PACsecure. The specific certifications a manufacturer needs depend on the markets they serve, the materials they process, and the food categories their packaging contacts. The sections below walk through each framework in detail so you can identify exactly which standards apply to your operation.
Which regulatory frameworks govern food-contact thermoformed packaging?
Food-contact thermoformed packaging is governed by a combination of national regulations, regional directives, and voluntary certification schemes. The two most influential regulatory frameworks are the US Food and Drug Administration (FDA) rules under 21 CFR and the European Union’s framework built around Regulation (EC) No 1935/2004, which sets the overarching principle that all food-contact materials must not transfer substances to food in quantities that endanger human health.
Beyond those two pillars, individual material-specific regulations layer on top. In the EU, plastics are specifically addressed by Regulation (EU) No 10/2011. In the US, the FDA’s food additive regulations and its “Generally Recognised As Safe” (GRAS) provisions determine which polymers and additives can legally contact food. Countries outside the EU and US often adopt frameworks closely modelled on one of these two systems, which means achieving compliance with both gives packaging manufacturers a strong foundation for global market access.
Voluntary food safety management standards such as ISO 22000 and GFSI-recognised schemes sit alongside these regulations. They are not laws, but major food brands and retailers increasingly require them as a condition of supply, making them effectively mandatory in practice for many thermoforming operations.
What certifications are most commonly required for thermoformed food packaging?
The most commonly required certifications for thermoformed food packaging are FDA compliance documentation (for US markets), conformity with EU Regulation 10/2011 (for European markets), and at least one GFSI-recognised food safety management certification such as FSSC 22000, BRC Packaging Issue 6, or IFS PACsecure. ISO 22000 is also widely referenced as a baseline food safety management standard.
In practical terms, a packaging manufacturer supplying yogurt cups or margarine tubs to a major European retailer will typically need to demonstrate:
- A Declaration of Compliance confirming that materials and articles meet EU Regulation 10/2011 limits
- Supporting documentation showing migration testing results for the relevant food simulants
- A certified food safety management system, most commonly FSSC 22000 or BRC Packaging
- Traceability records covering raw materials, production conditions, and finished goods
For manufacturers exporting to the US, FDA compliance letters or food contact notifications replace the EU declaration, but the underlying principle of documented safety evidence remains the same. Customers in the food and beverage sector, dairy processing, and coffee capsule production routinely specify which certification they require in their supplier qualification questionnaires, so understanding the landscape before entering a new market saves significant time and cost.
What does FDA compliance mean for thermoformed plastic packaging?
FDA compliance for thermoformed plastic packaging means that all materials, additives, and processing aids used in the packaging meet the requirements set out in Title 21 of the Code of Federal Regulations (21 CFR). The FDA does not issue a single “certificate” to packaging manufacturers; instead, compliance is demonstrated through documented evidence that every substance in the package is either listed in the relevant 21 CFR section or has received a Food Contact Notification (FCN) or a no-objection letter from the FDA.
For thermoformed plastics specifically, the most relevant 21 CFR sections cover polymers such as polypropylene (PP), polyethylene terephthalate (PET), polystyrene (PS), and polylactic acid (PLA). Each section specifies permitted additives, extraction limits, and conditions of use, including temperature ranges and food types. A thermoforming operation must ensure that not only the base resin but also any colorants, slip agents, antistatic additives, or recycled content comply with the applicable provisions.
Practically, this means working closely with resin and additive suppliers to obtain written declarations of FDA compliance, retaining those declarations as part of your quality documentation, and ensuring that any changes to materials or formulations trigger a fresh compliance review before production continues.
How does EU Regulation 10/2011 affect thermoforming machine settings and material choices?
EU Regulation 10/2011 on plastic food-contact materials directly influences both the materials a thermoforming operation can use and the process conditions under which packaging is produced. The regulation establishes an authorised Union List of monomers, additives, and other starting substances, sets overall migration limits (OML) of 10 mg per dm² of food contact surface, and defines specific migration limits (SML) for individual substances. Any plastic packaging that exceeds these limits cannot legally be placed on the EU market.
From a machine settings perspective, this has real implications. Migration rates are influenced by processing temperature, contact time, and the physical characteristics of the finished article. Excessive processing temperatures can cause degradation of polymers or additives, potentially creating migrating substances not present in the original material specification. This means that thermoforming machine parameters, including forming temperature, cycle time, and cooling efficiency, must be validated not only for dimensional and quality outcomes but also for their effect on material integrity and regulatory compliance.
Material choices are equally affected. Not every additive or colorant permitted in non-food plastics appears on the EU authorised list. Manufacturers must verify that every substance in the plastic formulation is either listed in Annex I of Regulation 10/2011 or falls within one of the permitted derogations. For operations processing recycled PET or biodegradable PLA, additional requirements apply, including the use of recycled content that has passed an EFSA-evaluated decontamination process for rPET.
What is the difference between ISO 22000 and FSSC 22000 for packaging manufacturers?
ISO 22000 is an internationally recognised food safety management system standard published by the International Organization for Standardization, while FSSC 22000 is a certification scheme built on top of ISO 22000 that adds sector-specific prerequisite programme requirements and is recognised by the Global Food Safety Initiative (GFSI). For packaging manufacturers, the key practical difference is that FSSC 22000 carries GFSI recognition, which ISO 22000 alone does not.
ISO 22000: the foundation
ISO 22000 defines the requirements for a food safety management system applicable to any organisation in the food chain, including packaging manufacturers. It combines HACCP principles with a process approach and covers hazard analysis, prerequisite programmes, and continual improvement. Achieving ISO 22000 certification demonstrates a structured, audited approach to food safety management and is respected across many markets.
FSSC 22000: the GFSI-recognised upgrade
FSSC 22000 incorporates ISO 22000 in full but adds ISO/TS 22002-4, which contains prerequisite programme requirements specifically written for food packaging manufacturers. These cover areas such as pest control, allergen management, labelling, and supplier approval in greater operational detail than ISO 22000 alone. Because FSSC 22000 holds GFSI recognition, major food retailers and brands that mandate a GFSI-benchmarked certification will accept it, whereas ISO 22000 alone may not satisfy their supplier requirements.
For a thermoforming operation deciding between the two, the choice often comes down to the customer base. If key customers or target markets require GFSI recognition, FSSC 22000 is the more commercially valuable investment. If the primary goal is establishing an internal food safety management framework with recognised third-party validation, ISO 22000 provides a solid and widely accepted foundation.
When should a thermoforming operation pursue GFSI-recognised certification?
A thermoforming operation should pursue GFSI-recognised certification when it supplies packaging directly to major food brands, retailers, or food service companies that mandate it as a condition of approval. GFSI-recognised schemes, which include FSSC 22000, BRC Packaging, and IFS PACsecure, signal to customers that an independent third party has audited the operation against a rigorous, globally benchmarked standard.
Beyond customer requirements, there are several situations where pursuing GFSI recognition makes strong commercial sense:
- Entering new markets: Many European and North American retailers will not list a packaging supplier without a valid GFSI-benchmarked certificate, making it a market access requirement rather than a differentiator.
- Scaling production: As output volumes grow, the structured food safety management system that underpins GFSI certification helps maintain consistent quality and traceability across higher-volume runs.
- Reducing customer audit burden: GFSI’s “once certified, accepted everywhere” principle means that a single third-party audit can replace multiple individual customer audits, saving time and resources on both sides.
- Processing sensitive food-contact applications: Packaging for dairy products, ready meals, or coffee capsules carries higher food safety scrutiny, and GFSI certification provides documented assurance to customers in those categories.
The investment in GFSI certification typically pays back through reduced audit costs, faster supplier approval processes, and access to customer segments that would otherwise remain closed.
