Abstract: A paperboard product has at least two or three plies. One of the plies has at least 25% by weight bulky cellulosic fibers. Another of the plies is an outer ply and has an outer surface having a Parker PrintSurf measurement of between 3 and 6? when measured at 10 kg/cm2 using a soft backing surface. The paperboard product has a density no greater than 0.5 grams per cubic centimeter. An embodiment has a caliper in the range of 0.4 and 1.2 mm. An embodiment has a basis weight in the range of 200 to 500 grams per square meter. A method for making the paperboard product by passing the web through a soft nip calender and an extended nip calender which can be a shoe calender under conditions which provide the surface and density properties.

Abstract: An insulating paperboard contains at least one layer of cellulose fibers. The one layer is at least partially composed of cellulosic fibers and fillers. The paperboard provides sufficient insulation to provide a hot water AT across the paperboard of at least 0.9° C. per 0.1 mm of caliper. A hot cup may be produced from the insulating paperboard.

Abstract: The barrier properties of a water soluble gas barrier material are improved if the material is blended with a nanoparticle calcium carbonate having a size of from 10 to 250 nanometers. The barrier material is on a substrate to provide a substrate with gas barrier properties. A layer of heat sealable material may be applied to the exposed surface of the barrier material. A method for making the barrier coated substrate is disclosed.

Abstract: A paperboard structure having gas barrier properties which is cost effective and durable. It uses linear low density polyethylene, metallocene-based linear low density polyethylene, or a blend of low density polyethylene and either linear low density polyethylene or metallocene-catalyzed linear low density polyethylene.

Abstract: A paperboard structure having gas barrier properties which is cost effective and reduces the effect of pinholes. The layer applied to the paperboard is a polyolefin and the product contacting the product is polyolefin. The polyolefin may be low density polyethylene, linear low density polyethylene, metallocene-catalyzed linear low density polyethylene, and a blend of low density polyethylene and either linear low density polyethylene or metallocene-catalyzed linear low density polyethylene. One of the two polyolefin layers has a weight of 18 to 26 g/m2 and the other polyolefin layer has a weight of 12 to 16 g/m2 if it is the product contacting layer or 5 to 10 g/m2 if it is the paperboard contacting layer.

Abstract: A paperboard structure having a five layer product side construction with an aliphatic gas barrier layer which is cost effective.
