Title
(EN) POST CONSUMER RESIN PACKAGING
(FR) EMBALLAGE EN RÉSINE DE POST-CONSOMMATION
Abstract
(EN) The present invention relates to a sustainable article for packaging which could be made substantially free of virgin petroleum-based compounds; in particular it relates to new packaging made from coloured post-consumer resin (PCR) having a high NIR absorption. A need remains to create a circular economy for coloured and/or black plastic by bringing the waste coloured and black plastic into new packaging while using Near infrared (NIR) detectable pigment in the colourant masterbatch. It is therefore an object of the present invention to bring the coloured or black plastic waste into new packaging. It has be found that a sustainable packaging in consumer acceptable black using NIR detectable pigment can be obtained by using a multilayer post-consumer resin, comprising a thinner outer layer of post-consumer resin of natural plastic waste (N-PCR); and a thicker inner layer comprising at least 50% coloured plastic waste (J-PCR).
(FR) La présente invention concerne un article durable pour emballage qui pourrait être sensiblement exempt de composés à base de pétrole vierge ; elle concerne, en particulier, un nouvel emballage fabriqué à partir d'une résine de post-consommation (PCR) colorée présentant une absorption élevée dans le proche infrarouge. Il est encore nécessaire de créer une économie circulaire pour le plastique coloré et/ou noir en transformant les déchets plastiques colorés et noirs en de nouveaux emballages tout en utilisant un pigment détectable dans le proche infrarouge dans le mélange maître de colorant. C'est pourquoi un objet de la présente invention est de transformer les déchets plastiques colorés ou noirs en de nouveaux emballages. On a découvert qu'un emballage durable d'un noir acceptable pour le consommateur utilisant un pigment détectable dans le proche infrarouge peut être obtenu à l'aide d'une résine de post-consommation multicouche, comprenant une couche externe plus mince de résine de post-consommation à base de déchets de plastique naturel (N-PCR) ; et une couche interne plus épaisse comprenant au moins 50 % de déchets plastiques colorés (J-PCR).
