Food packaging migration and taint testing and analysis

Scientist in laboratory

To discuss your needs

Ensuring safe food packaging or food contact materials through migration and taint analysis and testing is key to avoid loss of consumer confidence, brand damage and costly product recall.

Packaging migration and taints result from foreign chemical contamination in food, which can occur at any point of the global food supply chain and their analysis can be complex and challenging.

How we can help

Our knowledge of the relevant legislation, as well as technical expertise in food packaging migration and taint analysis, allow us to address issues and develop new analytical methods to support all stakeholders from developers, converters, to brands and retailers and ensure regulatory compliance.

We then either advise on further food packaging migration and taint analysis or take investigative action to determine root cause and prevent future occurrence.


It is important that packaging does not transfer its constituents, such as heavy metals and plastic monomers, into food and drink, to the detriment of the products quality.

We have a range of UKAS accredited methods for testing compliance with legal requirements for both heavy metal transfer and plastic migration from the packaging into the food.

As well as 'global' migration analysis, our non-exhaustive list of migration testing covers:


Consumers should expect a consistent experience. Chemical taints can arise through various routes and understanding the cause of a particular taint helps to prevent its recurrence.

Our non-exhaustive list of taint testing covers:

  • Sensory analysis of food and drink
  • Chemical analysis to determine the nature and severity of a problem
  • Off flavours in new product development
  • Flavour deterioration on storage
  • Taint analysis from packaging
