Food contact materials, analysis and consulting

WESSLING stands for the conformity of food contact materials: our specialists use the latest laboratory technology and competent expert services to ensure that your food contact products are safe for consumers.

Materials that come into contact with food must not negatively affect the quality of the food - in either chemical, physical or sensory terms. At the same time, the health of consumers must not be placed at risk.

Plastic

Food contact materials made of plastic

Plastics come into contact with food in various ways, e.g. in the form of drinks bottles, film packaging, kitchen utensils or during production in the form of seals and conveyor belts.

Food contact materials made of plastic can be drinks bottles.
Plastics can be manufactured from diverse materials such as polypropylene (PP), polyethylene (PE), polyethylene terephthalate (PET) or polystyrene (PS).

It is also crucial whether the paper is coated, printed or glued. It must also be determined whether the paper consists of recycled fibres, fresh fibres or a mixture of both. A qualified analysis and assessment must give consideration to these diverse types and possible uses. The basis of our laboratory analysis and consulting is the BfR Recommendations XXXVI, also the EuPIA Guideline if printing is involved, national specifications such as the Swiss Printing Ink Regulation as well as GMP Regulation (EC) no. 2023/2006.

Analysis and consulting - our range of services:

  • Testing according to BfR Recommendations XXXVI and XXXVI/1.–3., particularly for harmful substances such as formaldehyde, bisphenol A and phthalates
  • Testing of coated, printed and glued paper and cardboard products
  • Primary aromatic amines (paA) by means of photometry and LC-MS/MS
  • NIAS screening

Metal

Food contact materials made of metal

Metal items that come into direct contact with food include drinks cans, saucepans and vacuum flasks as well as screws and nuts.

Drinks cans are food contact materials made of metal
Food contact products made of metal often have epoxy resin coatings to protect against corrosion. Typical examples include lids of jars containing preserved vegetables or fruit. Our testing and consulting are based on the guideline "Metals and alloys used in food contact materials and articles" published by the EDQM (European Directorate for the Quality of Medicines & Health Care). It regulates the limit values for the migration of 21 metals into the test simulants citric acid 0.5% and test water after the first to third contact.

Analysis and consulting - our range of services:

  • Testing and confirmation of the conformity of 21 metals as per the guideline "Metals and alloys used in food contact materials and articles"
  • Harmful substances: lead and cadmium migration
  • Sensory testing
  • X-ray fluorescence analysis for determining metal
  • Risk-based SVHC screening

Our services in the field of epoxy resin coatings:

  • Migration analysis of BADGE/NOGE/BFDGE and bisphenol A as well as epichlorohydrin for metal food contact products coated with epoxy resin

Glass, ceramics, enamel

Food contact materials made of glass/ceramics/enamel

Complex legal regulations apply to items made of glass, ceramic or enamel that come into contact with food, e.g. glasses, cups or bowls.

Jam jars are food contact materials made of glass
Directive 84/500/EEC regulates food contact materials made of ceramic throughout the EU, including the limit values for cadmium and lead. Further specifications for glass and the limit values adopted from the EU Directive are set down in DIN 51032. Limit values in this product group are dependent on their characteristics, i.e. fillable or flat, for instance. The migration of lead and cadmium is regulated also for the brim of cups and glasses. Colouring metal compounds also play a role in the assessment. In addition to the limit values for the migration of lead and cadmium in glass and ceramic, enamelled glass and ceramic products were also regulated in DIN 51032. Our experts compile the scope of testing specified for your product on the basis of these regulations:

Analysis and consulting - our range of services:

  • Consulting for compiling the tests for each article
  • Metal migration: lead and cadmium
  • Sensory testing
  • Risk-based SVHC screening

Many different articles that come into contact with food are made of wood – cooking spoons, chopping boards or bread boxes, for example.

Chopping boards are food contact materials made of wood
It may be necessary to treat them with wood treatment products during production, and formaldehyde output can also occur. Analysis based on the applicable legal regulations is necessary. The sensory characteristics also play an important role in food contact materials made of wood.

Our range of services:

  • Consulting on the individual test scope
  • Formaldehyde
  • Wood preservatives
  • Chlorophenols (incl. PCP)

Dishwasher resistance testing

Dishwasher resistance testing after 125 rinsing cycles

The claim “dishwasher safe” gives consumers important information about the correct cleaning method for household items such as tableware, drinking glasses, sandwich tins or even plastic drinking bottles. It is a mark of the German Institute for Standardisation (DIN). It states that the products labelled with it can go through a certain number of rinses without showing any recognisable damage to their quality.

Our experts for the safety of food contact materials provide testing to producers of tableware, glasses and reusable plastic articles, according to the standards DIN EN 12875-1 mod. (2005-08), and DIN EN 12875-2 (2002-03). For this purpose, our laboratories have their own test dishwasher in which 125 rinsing cycles are carried out automatically.

According to DIN standards, the number of rinsing cycles must be between 125 and 1000. For this purpose, our laboratories have their own test dishwasher in which 125 rinsing cycles are carried out automatically. Our experts for the safety of food contact materials provide testing to producers of tableware, glasses and reusable plastic articles, according to the standards DIN EN 12875-1 mod. (2005-08), and DIN EN 12875-2 (2002-03). Special attention is paid to the durability of décors because their colour can fade when they are washed in the dishwasher, and the décor can even crack. The results are recorded by our consumer product experts in the form of photo documentation (before/after pictures).

Regulations and specifications

The EU's framework regulation, Regulation (EC) 1935/2004, regulates the requirements for all food contact materials. There are also further European regulations, directives, national legislation or recommendations which may differ extensively depending on the characteristics of the product.

The WESSLING experts keep an eye on the specifications: benefit from reliable laboratory analysis in combination with tailored expert services. Our specialists are certified for analysing official cross checks according to Section 43 of the German Food and Feed Code (LFGB).
