A smoking article includes a tobacco substrate and a filter segment comprising filtration material axially aligned in an abutting end to end relationship with the tobacco substrate. A hydrophobic plug wrap is disposed about the filtration material. The plug wrap is hydrophobic via hydrophobic groups chemically bonded to the plug wrap.

A molded pulp product including: a pulp, a water- and oil-resistant agent, and a water soluble polymer that does not dissolve in an aqueous medium at 40° C. or lower, wherein a content of the water soluble polymer is 1 to 50% by mass, based on the pulp.

The present invention relates to a paper or paperboard substrate having barrier properties, which substrate comprises a single or multiply structure with e.g. a top ply, a middle ply and a bottom ply, wherein at least one of said top ply and said bottom ply is provided with a high-density bio-barrier layer, and wherein said top or bottom ply provided with the high-density bio-barrier layer and said top or bottom ply not provided with the high-density bio-barrier layer have both been subjected to grafting with a fatty acid halide.

An applicator for providing an active composition to a surface, the applicator comprising a cellulosic substrate having anionic sites (e.g. paper, paper laminates, cardboard or a woven or non-woven plant fabric such as a wood pulp or cotton material); and an impregnated or coated composition, the impregnated composition comprising a bioactive cationic component in an amount sufficient in use to deactivate the anionic sites in the cellulosic substrate and to provide a desired effect, for example, a biocidal effect, enhanced skin feel, enhanced skin health and fabric softening. The applicator may be in the form of a sheet wipe, with a single or multiple layers of cellulosic substrate. The applicator is preferably substantially dry. Also, an applicator for providing an active composition to a surface, the applicator comprising at least two layers of cellulosic substrate having anionic sites; said layers being adhered to each other by an adhesive composition comprising a cationic component in an amount sufficient in use to deactivate the anionic sites in the cellulosic substrate and to provide a desired effect. The adhesive composition may also comprise a water-soluble or water dispersible adhesive polymer. Also methods of preparing and using the applicator e.g. to disinfect skin or an inanimate surface.

A germ-repellent paper product contains a paper substrate and a germ-repellent overprint varnish. The germ-repellent overprint varnish contains a varnish and a germ-repellent agent. The germ-repellent overprint varnish is coated onto the paper substrate to form a germ-repellent paper product. A method for manufacturing such a germ-repellent paper product is also provided.

The present invention relates to a method for hydrophobizing a cellulose substrate (1), which comprising a first side and a second side, which faces away from the first side, the method comprising the steps of: —drying the cellulose substrate to a dry content above 80%, preferably above 85%; —providing a fatty acid halide in spray form; —converting said fatty acid halide in spray form into vaporized fatty acid halide; and —guiding said vaporized fatty acid halide to contact the first side of the cellulose substrate, and at least partially penetrate the cellulose substrate.
