The invention relates to fiber sheets, to structures comprising the fiber sheets and to the use of the sheets. The invention further relates to biodegradable and/or recyclable products comprising the fiber sheets, useful in replacing non-biodegradable products.

A method and apparatus for manufacturing medical paper for medical sterilization packaging, medical paper and medical sterilization packaging are disclosed. A paper web is formed of fibrous substrate comprising cellulosic fibers and optionally synthetic fibers, with opposite first and second sides. On-line with the forming of the paper web, reinforcing material is applied on the first side and pressed into structure of the paper web such that delamination resistance of the structure is increased. Sealing material is applied on the second side of the paper web on-line with the forming of the paper web.

A water dispersible wipe includes a web including at least 10 weight % (wt. %) of a fibrillated regenerated cellulose microfiber (CMF) based on the total weight of the web, the remaining fibers of the web including natural cellulosic fibers; a wet strength agent disposed within the web; and a pH-modifying composition having a wetting pH disposed within the web; wherein the water dispersible wipe includes at least two webs and disperses upon exposure to an aqueous environment having a pH greater than the wetting pH and has a cross-direction (CD) wet tensile of at least 75 g/in after 24 hours as measured according to IVDA Standard Test WSP 110.4 (05).

A polyacrylamide resin has at least one kind of a first unit represented by the following formulas (1) to (4) and a second unit represented by the following formula (5).

##STR00001##

(In the above-described formulas (1) to (4), R1 represents a hydrogen atom, a methyl group, an ethyl group, or a benzyl group; R2 and R3 are independent and represent a hydrogen atom, a methyl group, an ethyl group, or a benzyl group; and X represents an anion.)

##STR00002##

(In the above-described formula (5), R4 represents a hydrogen atom or a methyl group and R5 represents a hydrogen atom, an alkali metal ion, or an ammonium ion.)

The present disclosure provides cellulose-based material and containers utilizing the cellulose-based material. More particularly, the present disclosure provides cellulose-based material comprising strength-enhancing preparations and improved containers made with the strength-enhanced cellulose-based materials.
