Toilet paper includes at least two sheets on which embossments are formed and that are joined together in a nested manner. The area of a top part of an embossed protrusion of each of the embossments is between 0.8 mm.sup.2 and 1.5 mm.sup.2, and the area percentage of top parts of embossed protrusions of the embossments is between 5% and 10%.

This disclosure relates to an apparatus for manufacturing a tissue paper product, such as toilet paper or household towel. The apparatus comprises an embossing unit comprising a first counter roll, a first heatable embossing roll, a second counter roll, and a second heatable embossing roll, and a marrying roll. The apparatus is configured to emboss a first ply between the first heatable embossing roll and the first counter roll, to emboss a second ply between the second heatable embossing roll and the second counter roll, and to ply-bond the first ply and the second ply between the first heatable embossing roll and the marrying roll.

The disclosed embodiments relate to an insulative protective packaging material constructed using recyclable paper materials. The packaging material includes one or more plies of paper adhered to each other. The one or more plies can have protrusions that form gas pockets. The gas pockets can be sealed by another ply to provide shock absorbency and insulation. Further, the plies can be used in multiple ways such as by nesting the protrusions of one ply into the recessed of another ply, layering multiple plies on top of each other, or individually. Each ply can be substantially flat or have protrusions. The protrusions can be made in various ways such as alternating the directions that they extend and varying the shapes of the protrusions. The resulting packaging material can be used as a shipping container or as liners within shipping containers.

A kitchen paper roll includes a kitchen paper that is formed by joining two sheets in a nested manner and is wound to form the kitchen paper roll. Each of the sheets includes an embossed region. The density of embossed protrusions on each of the sheets is greater than or equal to 0.075/mm.sup.2 and less than or equal to 0.2/mm.sup.2, the winding density of the kitchen paper is greater than or equal to 0.12 m/cm.sup.2 and less than or equal to 0.27 m/cm.sup.2, and the ratio of a minimum embossment area to a maximum embossment area in the kitchen paper is greater than or equal to 0.51.

Toilet paper includes at least two sheets on which embossments are formed and that are joined together in a nested manner. The area of a top part of an embossed protrusion of each of the embossments is between 0.8 mm.sup.2 and 1.5 mm.sup.2, and the area percentage of top parts of embossed protrusions of the embossments is between 5% and 10%.

Products having improved ply bonding, moldability and drape and methods for making those products are described. The methods comprise producing a multiply adhesively bonded product comprising a pattern of uniformly spaced microembossed elements with a bond area of less than about 0.020 inches/sq. inch.

An embossing device (1) includes three embossing rollers (5, 7, 9), each co-acting with a pressure roller (11, 15, 19), to emboss a plurality of paper plies (V1, V2, V3). Two embossing rollers can be easily interchanged to switch from a nested configuration to a tip-to-tip configuration, or to switch from one type of pattern to another. A lamination roller and a glue dispenser are arranged around one of the embossing rollers.

Products having improved ply bonding, moldability and drape and methods for making those products are described. The methods comprise producing a multi-ply adhesively bonded product comprising a pattern of uniformly spaced microembossed elements with a bond area of less than about 0.020 inches/sq. inch.

The disclosed tissue products have an embossing pattern that is aesthetically pleasing and provides improved product properties, such as good bulk, while reducing processing issues, such as wrinkling. The embossing patterns generally comprise a background and a foreground pattern where the background pattern is the dominate pattern and provides the product with a uniform appearance that connotes femininity, softness and cleansing. The background pattern is preferably formed entirely from open design elements such as first, second and third open, curvilinear line elements, wherein the second and third line elements are discrete, similarly shaped curvilinear line elements that are arranged parallel to one another and spaced apart about 1.0 mm or less.
