Compliant material solutions for the food industry

Producing food grade plastic compliant with the stringent requirements of FDA (Food and Drug Administration) and European Food Contact regulations is a key requirement for thermoplastics machining operators in this field. For the Chinese market the China GB standards have to be considered. With our standard engineering thermoplastic portfolio, we also offer a special portfolio of food contact materials, which meet the specific demands of food technology in terms of safety and performance.

Ensinger provides its compliant materials with a product specific food contact certificate, declaring FDA approval for raw material, compliance with Regulation (EC) 1935/2004, (EU) 10/2011 (migration test for plastic semi-finished products) as well as (EC) 2023/2006 on good manufacturing practice (GMP) for materials and articles intended to come into contact with food. For the Chinese Food market we offer declarations according to China GB standards GB 4806.1-2016 as well as GB 4806.6-2012 (positiv list for resins) and GB 9685-2016 (for additives).

Thanks to their light weight and easy-to-machine properties, food grade materials can replace metals in a variety of applications in plant and machinery for meat, fish and poultry processing, dairy products, baked goods and confectionery production. Ensinger's food contact materials  enhance production, speed and safety in the manufacturing process.

We also offer special plastics for the most common detection methods. As an alternative to conventional plastics, our portfolio includes blue materials for optical detection and plastics with multiple uses. These include our blue metal detectable products as well as metal and X-ray detectable materials for direct food contacts. We offer all these products in blue as standard. This increases safety during processing and also reduces costs.

Our technical office can assist you in choosing the most appropriate materials for your food contact plastics application, including the development of new materials

Benefits FOR THE Food Industry

Ensinger can provide food contact compliant plastics, which meet stringent quality and security requirements on production safety, seamless traceability and product certifications. The food portfolio includes materials compliant with FDA, EU 10/2011 and GB 4806.1-2016 regulations. Other regulations available on request.

Scrapers, valves and pistons, chain guiders, bushings, rollers, thrust washers, gear wheels, grippers, sliding bearings etc. these are only a few applications in food processing and packaging industry. As much as the applications can vary so, do the requirements, however, they all operate in a sensitive environment. Therefore, we offer a wide range of engineering and high performance plastics for various applications with or without food contact compliance.  

When replacing metals, one of the main factors to consider is the possibility of a more lightweight component, thanks to the use of plastics. For food technology, this could mean increased processing velocity and production efficiency.

When replacing components or sliding parts in metal with plastics, you can normally remove external lubrication, thus avoiding the risk of contamination of the food with oils or greases.  Ensinger provides food contact plastic compliant with stringent quality and security demands on production safety, seamless traceability and product certifications.
Choosing the right plastics for your food components which are regularly cleaned, sanitized or sterilized, means there is no need for additional protection against corrosion, as is normally required with metals (e.g. painting, surface treatment or selection of expensive special alloys). All of the Ensinger food grade plastics are resistant to cleaning agents to ensure the reusability and safety of components. In addition, the cleanliness of components can be more readily determined thanks to the use of blue materials, because spores, molds, food and detergent residues are more clearly visible by contrast than they would be with other coloured materials. 

In food processing lines, identifying possible fragments of plastic is a crucial function. Blue material for food contact and metal or x-ray detectable plastics in our portfolio can enhance the safety of food production processes, in full compliance with international regulations to control and limit possible migration of substances from the material to the food, to avoid any harmful influence.

Unlike other coloured materials blue plastics enure high visibility by contrast and therefore rapid in-line identification. In addition all food grade plastics from the ID series are produced by adding an additive that is detectable using metal detectors. Furthermore, our UD materials are modified with special additives that ensure both, metal and X-ray detectability. These plastics fully comply for contact with food in order to avoid contamination.

Frequently Asked Questions on Food Plastic Material

  • Semi-finished products or cut blanks are produced with plus tolerances in accordance with DIN so that the outer shell and consequently any discolouration or scuffing can be removed without fail during finished part production. 

  • The main objective is to exclude negative reciprocal impact between the plastic component and the contacted foods in the form of organoleptic, colour related and primarily toxic effects. Seamlessly applied declarations of conformity at every manufacturing level are key tools in the assurance of food safety. Added to this are traceability data using the methods of good manufacturing practice (GMP) implemented in quality assurance systems with verifiable documentation of product and process data.
  • Ensinger semi-finished plastics for food industry are compliant to directives for raw material approval of FDA regulations. Read more about FDA and Ensinger products.
  • Plastic stock shapes are not finished products with a final defined purpose and geometry as specified by the regulations. Final testing for the specific application requires knowledge of all application conditions. Influencing factors include the contact medium, contact time, and temperature and cleaning conditions. Consequently, no definitive and final assessment of migration values can be carried out on the component by the stock shapes supplier. This task remains the responsibility of the plant manufacturer or operator, on the basis of the migration limit information provided.
