Abstract: Un envase que debe tratarse en el autoclave, formado por un material de envase basado en fibras tratado conuna cola hidrófoba y que contienen en el interior y/o exterior del sustrato de fibra una o más capas para reducir lapenetración del agua, el envase se ha tratado a presión y a una temperatura de 100 a 250ºC durante un tiempo de 5min a 30 h, caracterizado porque el sustrato de fibra se ha tratado con una cola hidrófoba, un compuesto de aluminioy una cola resistente a la humedad para aumentar la resistencia al calor del material de envase, y porque la proporciónponderal entre la cola hidrófoba y el compuesto de aluminio es de 1:0,1-1:10.

Abstract: Polymer-coated, heat-sealable liquid packaging board that resists solvents (e.g. strong alcoholic drinks), method of manufacturing board, and drinking cup made of board. Resistance to solvents is achieved by lowering raw edge penetration into the board. The fiber base of the board contains at least 1.3 kg of hydrophobic size containing alkyl ketene dimer and at least 1.0 kg of wet-strength size per 1 ton of dry matter. Fiber base density is 630-800 kg/m3. The amount of heat-sealable polymer in the top layer is higher than the Bristow wheel roughness volume of the uncoated fiber base and/or at least 14 g/m2. When manufacturing the board, the alkyl ketene dimer size and a wet-strength size are added into the stock. The pH of the tail water is adjusted so as to be alkaline (about 7 or more).
