CONTROLLED COVERAGE ADDITIVE APPLICATION TO PAPER TISSUE

摘要

A soft tissue product (44) includes deposits of a surface additive compositi on disposed in primary (46) and supplementary (48) delivery zones having different add-on levels. The supplementary add-on level is greater than 0 an d less than the primary add-on level. For example, the supplementary add-on level may be from about 0.5 to about 80 percent of the primary add-on level. In particular embodiments, the primary delivery zones (46) cover from about 30 to about 90 percent of the tissue and the supplementary delivery zones (48) cover from about 10 to about 70 percent of the tissue. The different add-on levels effectively maximize consumer benefit while minimizing the total amou nt of additive on the tissue. One particularly beneficial method is to uniforml y apply the composition to the surface of the tissue web within each of the zones by rotogravure printing, either direct or indirect (offset), because i t is a very exact printing process and offers maximum control of the compositi on distribution and transfer rate. However, other applications methods, such as flexographic printing, spraying, extruding, and the like can also be used. A n engraved roll (23A, 23B) suitable for use in applying additives to tissue paper (44) is engraved with two different regions (40, 42; 50, 52) of cell patterns.
