| description | According to an example aspect of the present invention, there is provided a paperboard structure, comprising a paperboard substrate and a barrier coating layer on the paperboard substrate, wherein the paperboard substrate comprises folding boxboard or linerboard, wherein the barrier coating layer comprises microcrystalline cellulose and a polyester derived from succinic acid and/or adipic acid, wherein the average particle size of the microcrystalline cellulose ranges from 1 μm to less than 20 μm, wherein the barrier coating layer has been prepared by extruding a composition comprising microcrystalline cellulose and said polyester on the paperboard substrate.
Esillä olevan keksinnön yhden esimerkinomaisen näkökulman mukaan aikaansaadaan kartonkirakenne, joka käsittää kartonkisubstraatin ja sulkupinnoitekerroksen kartonkisubstraatilla, jossa kartonkisubstraatti käsittää taivekartongin tai lainerin, jossa sulkupinnoitekerros käsittää mikrokiteistä selluloosaa ja sukkiinihaposta ja/tai adipiinihaposta johdetun polyesterin, jossa mikrokristalliselluloosan partikkelikoko vaihtelee 1 μm ja alle 20 μm välillä, jossa sulkupinnoitekerros on valmistettu ekstrudoimalla koostumus, joka käsittää mikrokristalliselluloosaa ja mainittua polyesteriä, kartonkisubstraatille. |
