Publication number: 20260191370Abstract: A kitchen towel roll is provided that keeps basis weight within a prescribed range without excessively increasing it, and achieves a soft tactile feel and firmness while preserving strength and water absorption amount. The present disclosure relates to a kitchen towel roll obtained by bonding, with glue or water, sheets having an emboss pattern imparted to one or both of two plies, laminating the sheets to form a two-ply kitchen towel sheet, and winding the kitchen towel sheet into a roll, wherein: a basis weight of one ply of the kitchen towel sheet is 16 g/m2 to 27 g/m2; a dry MD-direction tensile strength DMDT and a dry CD-direction tensile strength DCDT are 600 gf/25 mm to 1500 gf/25 mm, a ratio of the DCDT to the DMDT (DCDT/DMDT) is 0.3 to 2.5; bending resistances in both the MD and CD directions are 4.5 mN to 22.0 mN; and a water-absorption amount per unit area is 330 g/m2 to 600 g/m2.Type: ApplicationFiled: November 29, 2023Publication date: July 9, 2026Applicant: Nippon Paper Crecia Co., Ltd.Inventors: Misa SHIMIZU, Yasunobu OOKA, Riho IINO, Hidehiko KAI

Publication number: 20120043372Abstract: The present invention aims to provide a cast-coated paper having good coated paper quality and printability combined with the property of decomposing hazardous substances upon exposure to light. A cast-coated paper prepared by applying a cast-coating layer based on a pigment and a binder on abase paper and finished by pressing the cast-coating layer in the wet state against a heated cast drum surface and drying it, wherein the cast-coating layer contains 1-30 parts by weight of titanium dioxide having an average secondary particle diameter of 300-2000 nm per 100 parts by weight of the pigment and the titanium dioxide is premixed with a silica sol or alumina sol at a ratio of the titanium dioxide to the silica sol or alumina sol of 2:1-1:2.Type: ApplicationFiled: June 7, 2007Publication date: February 23, 2012Applicants: NIPPON PAPER CRECIA CO., LTD., NIPPON PAPER INDUSTRIES CO., LTD.Inventors: Hiroshi Koyamoto, Koji Kutsuwa, Masashi Okamoto, Hidehiko Kai, Koji Okomori, Takashi Ochi, Noriyuki Ishibashi, Nobumasa Hayashi

Patent number: 6929845Abstract: A coated paper for gravure printing that offers good gravure printability resulting from reduced missing dots while at the same time achieving high sheet gloss, wherein the paper comprises a base paper and a coating layer containing a pigment and an adhesive. This paper also contains a compound having an effect of inhibiting the binding between pulp fibers, wherein the compound, when added to 0.3 weight-part per 100 parts of bone-dry pulp, will reduce the tensile strength of the paper by five % to 40% (as measured in accordance with JIS P 8133).Type: GrantFiled: September 27, 2001Date of Patent: August 16, 2005Assignee: Nippon Paper Industries Co., Ltd.Inventors: Hidehiko Kai, Koji Okomori, Chizuru Wakai, Hirokazu Morii, Hideki Fujiwara
