Abstract
(EN)
Embodiments of the present disclosure are directed to a vessel comprising a wall at least partially made of a compostable or biodegradable material, having an interior surface enclosing a lumen and an exterior surface; and a PECVD coating set on the interior surface, the exterior surface, or both. The PECVD coating set comprises a barrier coating or layer of SiOx, in which x is from about 1.5 to about 2.9 as measured by XPS. The PECVD coating set optionally further comprises a tie coating or layer comprising SiOxCy, in which x is from about 0.5 to about 2.4 and y is from about 0.6 to about 3 as measured by X-ray photoelectron spectroscopy (XPS); a pH protective coating or layer comprising SiOxCy, in which x is from about 0.5 to about 2.4 and y is from about 0.6 to about 3 as measured by XPS; or both. The vessel may also include a lacquer coating between the surface of the wall and the PECVD coating set. In some embodiments, the vessel may be a single use coffee or tea pod.

Selon certains modes de réalisation, la présente invention concerne un récipient comprenant une paroi au moins partiellement faite d'un matériau compostable ou biodégradable, ayant une surface intérieure renfermant un orifice et une surface extérieure ; et un ensemble de revêtement obtenu par dépôt chimique en phase vapeur assisté par plasma sur la surface intérieure, la surface extérieure ou les deux. L'ensemble de revêtement obtenu par dépôt chimique en phase vapeur assisté par plasma comprend un revêtement barrière ou une couche de SiOx, où x va d'environ 1,5 à environ 2,9 tel que mesuré par spectrométrie photoélectronique à rayons X. L'ensemble de revêtement obtenu par dépôt chimique en phase vapeur assisté par plasma comprend éventuellement en outre : un revêtement ou une couche de liaison comprenant du SiOxCy, où x va d'environ 0,5 à environ 2,4 et y va d'environ 0,6 à environ 3 tel que mesuré par spectroscopie photoélectronique à rayons X ; un revêtement ou une couche de protection du pH comprenant du SiOxCy, où x va d'environ 0,5 à environ 2,4 et y va d'environ 0,6 à environ 3 tel que mesuré par spectroscopie photoélectronique à rayons X ; ou les deux. Le récipient peut également comprendre un revêtement de laque entre la surface de la paroi et l'ensemble de revêtement obtenu par dépôt chimique en phase vapeur assisté par plasma. Selon certains modes de réalisation, le récipient peut être une dosette de café ou de thé à usage unique.
