EU regulations
Within the framework Regulation (EC) No 1935/2004 there are some specific measures on certain materials. One of these individual measures is Regulation (EU) No 10/2011 on plastic materials and articles intended to come into contact with food. This regulation, also known as the PIM (Plastics Implementation Measure), replaces the former "Plastics Directive" (2002/72/EC). In the meantime, a number of corrections and amendments to this regulation exist.
When plastics come into contact with food, components of the plastics can migrate to the food. The aim is to exclude, as far as possible, a health hazard due to such migration.
For this purpose, Regulation (EU) No 10/2011 establishes a positive list (Union list) of monomers and additives that may be used in the manufacture of plastic food contact materials and articles. Components of the Union list do not include polymerisation aids (catalysts, accelerators, initiators, etc.) or colourants. For "polymer production aids" (PPA) the Union list is not comprehensive. Substances not covered by the Union list are subject to national legislation and recommendations (e.g. the BfR recommendations).
Before inclusion in the Union list, substances have to be tested for their possible transfers to food and their toxicological properties. Based on these results, upper limits of permitted migration into food are set for some substances, so-called "specific migration limits (SML)". For all substances for which no SML was set, a "general SML" of 60 mg/kg applied for a long time. However, this was abolished at the end of 2016 with the amending Regulation (EU) 2016/1416. For substances for which such a specific migration limit (SML) cannot be verified, there are also quantitative restrictions (maximum concentrations) in the material (QM) instead. This limits or excludes a transfer to food as a precautionary measure. An overall limit is set for the sum of all substances migrated into the food, the "overall migration limit (OML)". This OML is defined as 10 mg per dm2 of the food contact surface of the material, or 60 mg per kg of food.
Substances that have not been evaluated must not be detectable in food. The generally accepted and practicable detection limit of 10 ppb (0.01 mg/kg) is considered "undetectable" today. This limit is also set in the amending Regulation (EU) 2016/1416 in Article 11, paragraph 4.
Polymers and substances with a molecular mass greater than 1,000 Daltons generally have little to no migration potential. Furthermore, these substances are not absorbed from the gastrointestinal tract and therefore pose virtually no toxicological risk in the eyes of the European Food Safety Authority (EFSA). Consequently, polymers and substances > 1,000 Daltons also have no significance in the sense of EU regulations and national laws and recommendations.
National regulations
The German Consumer Goods Ordinance (BedGgstV) can be regarded as the national counterpart to EU Regulation No. 10/2011. The BedGgstV lists the substances that may not be used in the commercial manufacture or treatment of certain consumer goods (§3, Annex 1) or may only be present in food consumer goods up to a certain maximum quantity (§6, Annex 5). The transfer of substances from plastics into food is also regulated in the BedGgstV (§6).
BfR recommendations
The focus of the recommendations was originally in the area of plastics for food contact. However, harmonised legislation now exists for plastics at European level, such as Regulation (EU) No 10/2011 in particular, which largely regulates this area. Many of the substances originally included in the Plastics Recommendations were gradually incorporated into the Consumer Goods Ordinance or the Union List and subsequently deleted from the BfR Recommendations.
For this reason, the BfR recommendations in the area of plastics now only take into account those substances that are not or not exhaustively covered by the Union list of EU Regulation No. 10/2011. These include the "aids to polymerisation", which include the components of the catalytic system (catalysts and initiators), and the "polymer production aids" (PPA), which include, for example, emulsifiers that are required in the manufacturing process.
FDA
In Title 21 of the Code of Federal Regulation (CFR), Parts 177 and 178 are particularly relevant for plastics. Part 177 - "Indirect Food Additives: Polymers" lists the different types of polymers in individual paragraphs. The requirements for polyolefins, for example, are in §177.1520 and those for polyurethanes in §177.1680. In "Part 178 - Indirect Food Additives: Adjuvants, Productions Aids, and Sanitizers", various additives, adjuvants and auxiliary substances are described in corresponding paragraphs. For example, the relevant paragraph for antioxidants is §178.2010 and colourants are regulated in §178.3297. In addition, the substances listed in the GRAS paragraphs (Parts 182-184) and the "Prior-Sanctioned Food Ingredients" (Part 181) can of course be used at any time.
If an additive is not listed in the paragraph intended for the intended use, it is still possible to use it based on the "no-migration" principle. If FDA-recognised migration studies show that the substance concentration in the food is below 50 ppb in the desired application, this principle can be applied on the company's own responsibility. For packaging materials with a high market share and thus a high consumer exposure, a limit value of 10 ppb is recommended by the FDA ("consumption factor").
Why we cannot guarantee final compliance when using our additives in food contact materials...
The migration potential of a particular substance can depend on many different factors, including:
- the type of plastic / polymer,
- the properties of the food (e.g. dry, watery, sour, fatty),
- Interactions with other plastic additives,
- the ratio between packaging surface and volume.
Therefore, the final compliance with the legal requirements has to be done by the manufacturer of the final food contact material / article of daily use, taking into account the respective use and conditions of use. For this reason, we recommend carrying out migration tests on the final product to check and confirm compliance. Testing can only be dispensed with if a limit crossing can be excluded from the ratio of packaging to product mass when assuming complete migration of the migrant (worst case). If you require more detailed information on our products in this regard, please do not hesitate to contact us. We will be happy to help you.
What we do for you...
We check as standard whether our products or their ingredients are included in the Union list of Regulation (EU) No. 10/2011. If our products contain polymers or substances with a molecular weight of > 1,000 Dalton only, we will be happy to advise you on request. Furthermore, we check the FDA status of our products. You can find the relevant information in our "Regulatory Information Sheets", which we will be happy to send you on request.
At your request, we will also be happy to check the conformity of our products with other national or industry-specific regulations. We are also happy to advise you on the selection of products suitable for food contact. Solutions that work.
