<p>The paper comprises an impregnated paper support comprising recycled cellulose fibers that are softwood cellulose fibers. A grinding degree of the recycled cellulose fibers is less than 50[deg] schopper riegler. A laboratory sheet consists of 100% recycled cellulose fibers, has a weight per unit area of 70 g/m 2>, a breaking strength in dry condition of 35 N/15 mm and/or a suction height of more than 0 mm, and is formed according to the rapid-kothen method. A splitting strength of the impregnated paper support is greater than 1.7 N/15 mm. The paper comprises an impregnated paper support comprising recycled cellulose fibers that are softwood cellulose fibers. A grinding degree of the recycled cellulose fibers is less than 50[deg] schopper riegler. A laboratory sheet consists of 100% recycled cellulose fibers, has a weight per unit area of 70 g/m 2>, a breaking strength in dry condition of 35 N/15 mm and/or a suction height of more than 0 mm, and is formed according to the rapid-kothen method. A splitting strength of the impregnated paper support is greater than 1.7 N/15 mm. One side of the paper support is provided with a separating layer. The paper support has a bonding agent layer on the opposite side of the separating layer. The paper is calendared between a steel roller and a rubber roller at a splitting pressure of 30-300 N/mm and a temperature of 20-70[deg] C. An amount of recycled cellulose fibers in the impregnated paper support is greater than 90% based on the total of cellulose fibers. An independent claim is included for a method of producing a paper for adhesive tapes.</p> |
