Title (EN) HEAT SEALABLE COATING
(FR) REVÊTEMENT THERMOSCELLABLE
Abstract:
(EN) The present invention relates to a heat sealable and water repellent coating and a substrate comprising said heat sealable and water repellent coating that can be used in the manufacture of drinking cups or food boxes, in particular hot drinking cups or hot food boxes. Said heat sealable and water repellent coating comprises a cyclic imide co-polymer, at least two adhesive binders, of which one of these is a polymer with a Tg lower than -20°C and a molecular weight above 25000 Da, said polymer being selected from the group comprising natural rubber, polyacrylate, polystyrene butadiene, polybutene, polyisobutene, polyisoprene; preferably natural rubber, and a tackifying agent. Due to its specific characteristics, the heat sealable and water repellent substrate comprising the coating according to the present invention is biodegradable, recyclable and repulpable.
(FR) La présente invention concerne un revêtement thermoscellable et hydrofuge et un substrat comprenant ledit revêtement thermoscellable et hydrofuge qui peut être utilisé dans la fabrication de tasses de boisson ou de boîtes d'aliments, en particulier de boissons chaudes ou de boîtes d'aliments chauds. Ledit revêtement thermoscellable et hydrofuge comprend un copolymère imide cyclique, au moins deux liants adhésifs, dont l'un est un polymère présentant une Tg inférieure à - 20 °C et un poids moléculaire supérieur à 25 000 Da, ledit polymère étant choisi dans le groupe comprenant le caoutchouc naturel, le polyacrylate, le polystyrène-butadiène, le polybutène, le polyisobutène, le polyisoprène ; de préférence le caoutchouc naturel, et un agent collant. Du fait de ses caractéristiques spécifiques, le substrat thermoscellable et hydrofuge comprenant le revêtement selon la présente invention est biodégradable, recyclable et retriturable.
