FEICA issues guidance on adhesive migration tests

On 27 May, the Association of the European Adhesive and Sealant Industry (FEICA) published a new advisory document on conformity testing adhesives in food contact materials.

The guidance paper – Migration Testing of Adhesives Intended for Food Contact Materials – has been issued as part of a broader FEICA project on food contact.

The 12-page paper is free to download. It recommends tests using the food simulant Tenax to track migration. The document has been prepared by FEICA’s Paper and Packaging Technical Working Group, and while there is a focus on these materials, other packaging substrates are also considered.

The authors note: ‘Due to the wide range of applications and the complexity of the chemistry, no unified testing conditions can be defined for adhesives,’ and that while some provision is made for those used with plastics in the EU Regulation 10/2011 these have ‘limitations.’

Separate guidance and considerations are given for testing:

  • Polyutherane-based adhesives
  • Vinyl acetate polymers (PVAc) or ethylene vinyl acetate (EVA) copolymer adhesives
  • Natural polymer-based adhesives
  • Acrylic polymers adhesives
  • Cold seals
  • Hot seals
  • Hot-melt adhesives.

The new guidance paper joins other advisory documents published by FEICA – including its 2014 Guidance for a food contact status declaration for adhesives; and its 2015 Guideline for Good Manufacturing Practice of food packaging adhesives.
