Publication number: 20120318253Abstract: Disclosed is a porous film for a bag-constituting member prepared by stretching an unstretched film to be porous. The unstretched film is made from a material composition essentially including a linear low-density polyethylene; an olefinic copolymer having a Vicat softening point of from 20° C. to 50° C. and a density of less than 0.900 g/cm3; and an inorganic filler. The porous film excels in low-temperature heat sealability and gives a bag-constituting member for a body warmer.Type: ApplicationFiled: June 1, 2012Publication date: December 20, 2012Applicant: NITTO LIFETEC CORPORATIONInventors: Hiroshi Nagami, Yasuhiro Takeda

Publication number: 20110130814Abstract: An air-permeable member for portable body warmers includes a nonwoven fabric and a porous film in a layered structure. The nonwoven fabric is a spunbonded nonwoven fabric having an embossment area ratio of 5% to 20% and a METSUKE of 10 to 80 g/m2, the porous film has a thickness of 30 to 200 ?m, and the air-permeable member has a compressive strength in machine direction of from 2 to 5.5 N as a maximum compressive load measured through a ring crush method by sampling a 60-mm square test piece; rounding the test piece with a circumference agreeing the transverse direction to give a cylindrical sample; compressing the cylindrical sample in the machine direction using a tensile tester at a temperature of 23° C. and relative humidity of 50% at a compressing speed of 300 mm/min.; and measuring compressive loads at distortions of 0 to 10 mm.Type: ApplicationFiled: June 18, 2010Publication date: June 2, 2011Applicant: NITTO LIFETEC CORPORATIONInventors: Masaki Nagano, Yasuhiro Takeda

Patent number: 7950385Abstract: A disposable warmer of the present invention has a bag including a bag member (A) and a bag member (B); a heater; a heat-sealed portion where the bag member (A) and the bag member (B) are heat-sealed; and a portion with the heater sealed therein. The bag members (A) and (B) are heat-sealed with each other to form the bag, the bag member (A) includes at least a layered structure with a porous film and a nonwoven fabric layer, and the bag member (B) includes at least another layered structure with a stretchable film and another nonwoven fabric layer. The disposable warmer comprises two or more of the portions with the heaters sealed therein independently, and a slit in at least the porous film constituting the bag member (A) of the bag members (A) and (B) in at least one region between the adjacent portions with the heaters sealed therein.Type: GrantFiled: May 19, 2008Date of Patent: May 31, 2011Assignee: Nitto Lifetec CorporationInventors: Kaori Ohnishi, Katsumi Hori

Publication number: 20110076430Abstract: This invention provides a pressure-sensitive adhesive sheet having a base material and a pressure-sensitive adhesive layer containing a urethane resin or a styrene copolymer and also containing hollow microspheres and bubbles, formed at least on one side of the base material. This invention also provides a disposable body warmer having the pressure-sensitive adhesive sheet as a bag-constituting component.Type: ApplicationFiled: September 24, 2010Publication date: March 31, 2011Applicant: NITTO LIFETEC CORPORATIONInventor: Yoshitake Shigematsu

Publication number: 20100310854Abstract: A porous film for a heat-sealable bag-constituting member is prepared by stretching an unstretched film to be porous. The unstretched film includes an ultrahigh-molecular-weight polyethylene having a weight-average molecular weight of 30×104 to 250×104, a polyolefin component other than the ultrahigh-molecular-weight polyethylene, and an inorganic filler as essential components, and the content of the ultrahigh-molecular-weight polyethylene is 1 percent by weight or more based on the total amount of polymer components constituting the porous film. Even when produced by stretching at a low draw ratio, the film does not suffer from uneven stretching and shows high productivity. When the film is heat-sealed into a bag, the bag has a high seal strength and does not suffer from edge tear. The film is therefore useful particularly as a bag-constituting member to be heat-sealed into a bag typically as a disposable body warmer.Type: ApplicationFiled: January 27, 2009Publication date: December 9, 2010Applicant: NITTO LIFETEC CORPORATIONInventors: Hiroshi Nagami, Kaori Ohnishi
