Coated paperboards and paperboard containers having improved tactile and bulk insulation properties |
| abstract |
An improved paperboard has been bulk enhanced by retaining a substantial portion of bulk-enhanced additives including expandable microspheres in a suitable distribution within the paperboard. The cellulosic paperboard web has an overall fiber weight (w) of at least 40 lbs. per 3000 square feet and, at a fiber density of 3, 4.5, 6.5, 7, 8.3 and 9 pounds per square foot ream at a fiberboard thickness of 0.001 inches, has a GM Taber stiffness of at least about 0.00246w2.63 grams-centimeter/fiber mat density1.63, and a GM tensile stiffness of at least about 615 + 13.18w pounds per inch. The high retention of the bulk enhancing additives is believed to result from the incorporation of suitable retention aids. The resulting paperboard has better GM Taber stiffness values and GM tensile stiffness than prior art paperboards. The paperboard also has increased strain to failure and is able to be formed into suitable paperboard containers without loss of integrity. The resulting containers have increased hold times when they contain hot or cold food or drink. |
