FIELD: transportation, package.
SUBSTANCE: invention can be used for producing packages for storing liquid food products and other products containing liquid. The packaging of the autoclavable product is made of packaging cardboard. Mentioned cardboard comprises a fibrous substrate and one or more layers of polymeric coating, which is applied to one or both sides of the fiber base. The fibrous base comprises a combination of alkilketendimer (AKD) glue, stearic anhydride (SA), and glue, which enhances the strength in wet state, and aluminum compounds. The packaging is autoclaved at a temperature of at least 130°C.
EFFECT: invention allows to give the cardboard packaging the resistance to aggressive liquids, resistance to heat treatment, high resistance to liquid penetration through the raw edge under these influences.
