Masterbatches In Contact With Food

Particularly high requirements are set for polymers that come into direct contact with food and beverages. Prudent monitoring of all raw materials used and GMP production processes form the base requirements for solutions for safer use.

Manufacturers must comply with the pertinent local guidelines and regulations - depending on the market for which they are producing. Such as the EU regulation 10/2011 “on materials and articles intended to come into contact with food.”

Colourant is exclusively used for colouring polymer products that come into contact with food, such as packaging or cooking and baking utensils. It does not migrate out of the polymer, is chemically inert and complies with EU regulation 10/2011.

Strict regulations don’t just apply to specialised integral components, such as base polymers and additives. Unintentionally added substances called NIAS (Non-Intentionally Added Substances) also need to be considered.

NIAS can enter into the product in the form of outside contaminants. Other causes are the contamination of raw materials that are used in product production, or substances that are formed during processing. For example, accidental overheating of the content or of the packaging materials during the manufacturing process.

Some NIAS can be anticipated with a clearer understanding of the manufacturing process and conditions of use. Others can only be detected with widely instituted screening methods. In this way, many NIAS can be identified that would otherwise remain hidden, such as with optional GC tests (GC: gas chromatography).

Lifocolor, of course, considers the various international guidelines and manufacturing requirements when developing masterbatches. Raw materials are also carefully chosen. Relevant certificates of conformity guarantee that the necessary information is passed on along in the supply chain. In this way, polymer product manufacturers can run the necessary and mandatory tests.

Optimal protection of filling materials is another requirement for polymer food packaging. Appropriate additive masterbatches and combi-batches are also helpful here.

Another aspect to consider for polymer food packaging is reliable product labelling and guaranteeing authenticity. These are achieved with contrasting masterbatch solutions for laser labelling.
