L’utilisation de cette solution colorante dans des emballages rigides en PE avec un taux d’intégration inférieur ou égal à 4% permettra à l’emballage d’être détecté et orienté vers le flux d’emballages en PE avec des performances satisfaisantes. Cet avis est valable lorsque la solution colorante : - est utilisée dans la fabrication d’emballages rigides en PE ; - à un taux d’intégration maximal de 4% ; - n’est pas utilisée avec des chutes de production, d’autres solutions colorantes ou des matériaux recyclés pouvant contenir du noir de carbone. En effet, les emballages rigides en PE intégrant 4% de solution colorante noire CESA® IR PE 94000816 sont détectés et orientés vers le flux PE avec les mêmes performances (qualité, taux de captage) que les autres emballages rigides ménagers en PE.
