A pallet container for storing and transporting in particular flammable or easily ignitable liquid filling materials includes a thin-walled rigid internal container made from a thermoplastic plastics material, a tubular lattice frame that as a supporting jacket tightly encloses the plastics-material internal container, and a base pallet on which the plastics-material container bears and to which the tubular lattice frame is fixedly connected. The plastics-material internal container on all sides is enclosed by a fire-protection insulation mat which, while dispensing with a sheet-metal sheathing on all sides, is disposed directly between the tubular lattice frame and the plastics-material internal container. The fire-protection insulation mat is configured in a double-layered manner, and has an internal layer made from a heat-resistant non-woven and an external heat-resistant woven-fabric textile layer.
