Bonjour,

Il s'agit d'une d'une enquête sur l'utilisation d'un substitut au bisphénol A.

"This new material has the same irreplaceable ***coating effects*** as BPA-based can coatings, which makes them perfect for food safety and preservation. The promise of this new material is that it doesn't use BPA or harmful chemical substitutes as an ingredient."

Je pensais à "effets de recouvrement" pour "coating effects" mais sans certitude. Auriez-vous d'autres suggestions ? Merci.
