What food contact regulations apply to thermoformed plastic cups in the EU?

For any manufacturer producing plastic cups for food applications, navigating EU food contact regulations is not optional. It is a legal prerequisite that shapes every stage of production, from material selection to machine calibration. Whether producing yogurt tubs, beverage lids, or ready-meal containers, understanding which rules apply and how to demonstrate compliance is essential for accessing European markets and maintaining customer trust.

The regulatory landscape for food contact materials in the EU is detailed and evolving. Getting it right requires more than simply choosing approved materials. It demands documented processes, traceable supply chains, and production equipment precise enough to deliver consistent results batch after batch. This guide breaks down the core requirements that apply to thermoformed plastic cups in the EU context.

Key EU legislation governing food contact plastics

The foundation of EU food packaging compliance rests on Regulation (EC) No 1935/2004, the overarching framework that governs all materials and articles intended to come into contact with food. It establishes the general principle that food contact materials must not transfer substances to food in quantities that could endanger human health, change food composition in an unacceptable way, or deteriorate the taste and odour of food.

Sitting beneath this framework is Regulation (EU) No 10/2011, which is the specific measure covering plastic food contact materials and articles. This is the regulation most directly relevant to thermoformed plastic cups. It defines the Union list of authorised monomers, additives, and other starting substances, sets overall migration limits (OML) and specific migration limits (SML) for individual substances, and establishes testing and documentation requirements. Manufacturers and converters working with PS, PP, PET, or other thermoplastics in food packaging must demonstrate that their finished articles comply with the migration limits set out in this regulation.

Specific requirements for thermoformed cup materials

Not every plastic is treated equally under EU rules. The specific requirements for thermoformed cup production depend heavily on the polymer used and the food type it will contact.

Regulation (EU) No 10/2011 assigns food simulants that must be used during migration testing, matched to the type of food the packaging will contain. Aqueous foods, fatty foods, dry foods, and alcoholic beverages each require different test conditions. A cup intended for dairy products such as yogurt, for instance, must be tested using the appropriate simulant for fatty and aqueous food contact, reflecting the actual conditions of use.

Beyond migration testing, the regulation also requires that plastic food contact materials comply with compositional restrictions. Only substances included on the positive list may be intentionally used. This places responsibility on both material suppliers and converters to verify that every input substance is authorised and used within the permitted conditions. For thermoforming specifically, the processing temperatures and forming conditions must not degrade materials in ways that generate non-authorised breakdown products.

Declaration of compliance and traceability obligations

Compliance with EU food contact regulations must be documented and communicated throughout the supply chain. Regulation (EU) No 10/2011 requires that a Declaration of Compliance (DoC) accompanies plastic food contact materials at all business-to-business stages of the supply chain. This written declaration must confirm that the material or article complies with the applicable regulations and must be supported by appropriate technical documentation.

That supporting documentation typically includes migration test reports, certificates of conformity from raw material suppliers, and internal quality records demonstrating that production conditions remained consistent with those used during testing. Traceability is equally important. Businesses must be able to identify from whom materials were purchased and to whom finished articles were supplied, enabling a rapid response in the event of a compliance issue or recall.

For cup producers operating at scale, maintaining this documentation across multiple material grades, production runs, and customer specifications is a significant operational task. Building traceability into production workflows from the outset is far more efficient than reconstructing records after the fact.

How machine precision affects regulatory compliance

Regulatory compliance for thermoformed plastic cups is not purely a materials question. The performance of the forming machine itself plays a direct role in whether finished articles consistently meet the standards set during migration testing and qualification.

Migration test results are generated under defined conditions using specific material samples. If the forming process introduces variability in wall thickness, material distribution, or surface temperature, the finished article may differ meaningfully from the tested sample. Inconsistent forming can lead to localised thinning, stress points, or incomplete crystallisation in semi-crystalline polymers, all of which can affect migration behaviour and mechanical integrity.

Parallelism between the forming tool and the sheet is a particularly important factor. Uneven clamping forces or tool misalignment produce cups with non-uniform wall thickness, which not only affects product quality but can also compromise the validity of compliance testing performed on representative samples. High-precision machines with stable forming stations and controlled motion sequences reduce this variability, making it easier to produce articles that reliably reflect the conditions under which they were tested and approved.

Emerging regulatory changes to prepare for

The regulatory environment for plastic food contact materials in the EU is not static. Several developments in 2026 and the coming years are relevant for producers of thermoformed cups.

The revision of Regulation (EU) No 10/2011 has been under discussion as part of a broader update to EU food contact material legislation. The European Commission has signalled its intention to introduce a more comprehensive and modernised framework that addresses recycled plastics more explicitly, tightens restrictions on certain substances of concern, and potentially introduces new requirements around the use of functional barriers.

Sustainability-driven regulation is also gaining momentum. The EU’s packaging and packaging waste legislation is pushing towards increased use of recycled content and improved recyclability. For thermoformed cup producers, this means growing interest in materials such as recycled PET and bio-based alternatives like PLA. Regulatory acceptance of these materials for food contact applications is developing, and producers should monitor guidance from the European Food Safety Authority (EFSA) and national competent authorities closely.

Track EFSA opinions on recycled plastic processes authorised under Regulation (EC) No 282/2008
Monitor Commission updates on the revision of the plastic food contact materials regulation
Review how new packaging waste targets under the revised PPWR may affect material choices and design requirements
Assess whether current migration testing covers the full range of materials being considered for future production

Staying ahead of these changes requires active monitoring and a willingness to adapt qualification processes and supplier relationships before new requirements become mandatory.
