Abstract (en)
An insulating paperboard (12) contains at least one layer (14) of cellulose fibers. The one layer is at least partially composed of bulky fibers. The paperboard is sufficiently insulated to provide a hot water ”T across the paperboard of at least 0.7°C ± 2.3°C per 0.1 mm of caliper. The paperboard may be embossed to decrease surface transmission of heat. A hot cup may be produced from the insulating paperboard.
