A method for forming a package including a stack of absorbent tissue paper material and a packaging, the tissue paper material in the stack forming panels having a length, and a width perpendicular to the length, the panels being piled on top of each other to form a height extending between a first end surface and a second end surface of the stack, and the packaging encircling the stack so as to maintain the stack in a compressed condition in the package, with a selected packing density D0 of the stack, and a selected packing height H0; the method including: forming the stack of absorbent tissue paper material; compressing each portion of the stack in a direction along the height to assume a temporary height H1 being c1H0, where c1 is between 0.30 and 0.95; and applying the packaging to the stack.

The present invention provides soft, durable and bulky tissue products comprising non-wood fibers and more particularly hesperaloe fiber. The inventors have discovered that high yield hesperaloe pulp fiber, when incorporated in amounts of at least about 5 percent by weight of the tissue product, produces products having a GMT less than about 1000 g/3 and a GM Slope less than about 7.0 kg. At the foregoing tensile strengths and modulus the tissue products of the present invention are also generally soft, such as having a Stiffness Index less than about 10.0, and more preferably less than about 9.0, such as from about 7.0 to about 9.0.

The present invention relates to tissue products comprising high yield hesperaloe fiber having improved wet performance, such as improved absorbency, CD Wet/Dry Ratio and CD Wet Durability. The addition of high yield hesperaloe pulp fibers surprisingly improves the CD Wet/Dry ratio without negatively affecting the absorbency of the tissue product. For example, tissue products of the present invention generally have an Absorbent Capacity greater than about 6.0 g/g, such as from about 8.0 to 8.0 g/g. As such the tissue products are durable when wet, but are still sufficiently absorbent. This balance of absorbency and wet strength is not found in the prior art without resorting to adding latex binders or the like to the tissue product.

An absorbent composite foam is provided having a density below 0.04 g/cc and low wet collapse comprising (i) between about 5 to about 40% by wt. fluid resistant fibers; (ii) between about 30 to about 80% by wt. cellulosic fibers; (iii) between about 5 to about 35% by wt. binder; and (iv) a foaming surfactant. The combination of ultra-low density and wet stability is achieved, despite a high proportion of cellulosic fibers, by having both hydrogen bonding between cellulosic fibers as well as inter-fiber bonds formed by the binder.

A cellulosic sheet includes a single ply providing a first surface of the cellulosic sheet on one side and a second surface of the cellulosic sheet on a second side. The single ply has a caliper of at least about 130 mils/8 sheets, a basis weight of less than about 16 lbs/ream, and a dry machine direction/cross machine direction (MD/CD) tensile ratio of less than about 1.0.

A single-ply tissue paper material having a basis weight less than 40 gsm and an absorbency of at least 3 g/g, comprising a non-wood tissue ply, said non-wood tissue ply comprising non-wood cellulose pulp fibres in an amount of at least 10% by dry weight of the non-wood tissue ply. The disclosure further relates to a single-ply tissue paper product, and a multi-ply tissue paper product.

Paper products can comprise a first plurality of fibers that are hardwood fibers and a second plurality of fibers that include softwood fibers and surface enhanced pulp fibers (SEPF). The paper product can include one or more first fiber layers that comprise the first fibers, at least one of the first fiber layer(s) defining one of opposing upper and lower surfaces of the paper product, and one or more second fiber layers that comprise the second fibers. When a tissue, by weight, between 50% and 80% of the tissue's fibers can be the first fibers and at least 20% of the tissue's fibers can be the second fibers. The tissue's basis weight can be less than or equal to 21 gsm per ply.

Paper products such as tissues can be made using a furnish comprising surface enhanced pulp fibers (SEPF). In some embodiments, SEPF have a weighted average fiber length of at least 0.3 millimeters (mm) and an average hydrodynamic specific surface area of at least 10 square meters per gram (m.sup.2/g). In some embodiments, a furnish or a paper product can comprise at least 2% SEPF by dry weight. In some embodiments, a paper product comprising SEPF can be formed from a furnish having a freeness of 650 ml Canadian Standard Freeness (CSF) or less, optionally 600 ml CSF or less.

Products having improved caliper, sheet bulk and absorbency and methods for making those products are described. The method, comprises producing a multi-ply product having different emboss patterns on each ply where the emboss patterns are made up of emboss elements having an aspect ratio of from about 1 to about 2.

The present disclosure is directed towards a paper product which can remain intact prior to and during usage and can self-disintegrate over time. Such a paper product can occupy less space in a user's waste bin following usage when compared with a similar paper product that does not self-disintegrate. Such a paper product can be treated with a topical binder that includes a sublimable material. The sublimable material can sublime away from the paper product over time thereby reducing the ability of the fibers of the paper product to remain bonded together.
