Soft-single ply tissue having very low sidedness

A single-ply tissue product having a serpentine configuration comprising a single-ply tissue formed by conventional wet pressing of a cellulosic web, adhering said web to a Yankee and creping said web from said Yankee, said tissue comprising at least two structurally uniform but compositionally differentiated strata which are not delaminated from each other, including:

• a first stratum comprising cellulosic papermaking fiber chosen from the group consisting of hardwood, softwood, and recycled fibers and cationic nitrogenous softener/debonder, and optionally, strength enhancing agent, said first stratum having been in contact with said Yankee and has been creped.
• a second stratum which has not been in contact with the Yankee and has not been creped comprising cellulosic papermaking fiber chosen from the group consisting of hardwood, softwood, and recycled fibers, and cationic nitrogenous softener/debonder, and optionally, strength enhancing agent;
• the overall concentration of cationic nitrogenous softener/debonder in said single ply tissue product being between about 1 to about 8 lbs/ton;
• the concentration of strength enhancing agent in the first stratum being from at least about 1 to about 6 lbs/ton whenever the amount of hardwood in the second stratum exceeds 25%;
• the concentration of strength enhancing agent in said second stratum being no more than the greater of about 0.5 lbs/ton or 20% of the concentration of said strength enhancing agent in the first stratum whenever the amound of hardwood in the second stratum exceeds 25%;
• the relative amounts of softwood fibers, recycle fibers, hardwood fibers, strength enhancing agent, and cationic nitrogenous softener/debonder in each of said strata being selected such that said tissue exhibits:
• a sidedness parameter of less than 0.3, a tensile modulus of no more than 32 grams/percent strain, a GM MMD friction of no more than about 0.225, a cross directional dry tensile strength of at least 200 grams per 3 inches.
