• a) impregnating a corrugated paper medium with hydrogenated triglyceride (HT);
• b) impregnating a first paper liner board solely through its wire side with HT;
• c) impregnating a second paper liner board solely through its wire side with HT;
• d) coating said impregnated first paper liner board on its felt side with a coating which is a styrene acrylic co-polymer solution having 40% to 70% solids;
• e) coating said impregnated second paper liner board on its felt side with a coating which is a styrene acrylic co-polymer solution having 40% to 70% solids;
