Abstract
An adhesive tape is made by hot calendering a substrate between two generally identical rolls one of which is heated to a different temperature than the other roll while rotating the rolls at the same peripheral speed to flatten one face of the substrate and reduce air permeability of the substrate by at least 15%. Then an adhesive coating is applied to at least one of the faces of the substrate.
