Tape backing substrate

摘要

There is disclosed a cloth-like tape substrate. The substrate is made from an essentially unbonded cellulose web having a breaking length between about 0.71 km and 2.66 km which is saturated with a soft rubber-like polymer, coated with a low stiffness polymer, and then embossed. The unbonded web is formed from at least 25% by weight of pulp having R10 values greater than 94%. The soft rubber-like polymer has a glass-transition temperature between -50 DEG C. and 0 DEG C. and the low stiffness polymer coating has a tensile modulus less than 1,000 MPa.
