摘要： A base film for pressure-sensitive adhesive tapes and sheets which comprises a tackifier resin; and a pressure-sensitive adhesive tape or sheet which has a film having at least one layer of the base film as a substrate and a pressure-sensitive adhesive layer formed on at least one face of the substrate. Pressure-adhesive tapes or sheets which have excellent effects of undergoing little dimensional change even under heating or with the passage of time, showing good appearance without suffering from gapping, etc. in case of rolled tapes and sustaining stable pressure-sensitive adhesive force. Particularly favorable effects can be achieved in pressure-sensitive adhesive tapes wherein a polyolefin resin is used as the base film and a rubber pressure-sensitive adhesive containing a large amount of a tackifier resin is used as the pressure-sensitive adhesive.

摘要： The present invention provides an impact absorption sheet for flat panel display with a polyoxyalkylene-series polymer as the main component, preferably, an impact absorption sheet for flat panel display made of a cured product obtained by curing a composition containing (A) polyoxyalkylene-series polymer having at least one alkenyl group in each molecule, (B) compound having an average of 2 or more hydrosilyl groups in each molecule, and (C) hydrosilylation catalyst.According to the present invention, an impact absorption sheet for flat panel display can be obtained, which can meet the size reduction and weight reduction of flat panel display, and which affords practically sufficient impact absorbability even in an area of thin film where practically sufficient impact absorbability has not been conventionally achieved. According to the present invention, moreover, an impact absorption sheet for flat panel display can be obtained, which not only has superior impact absorbability but is also superior in easy adhesion to flat panel display and redetachability after adhesion.

摘要： 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.

摘要： 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.

摘要： A pressure-sensitive adhesive tape comprising a substrate having thereon at least two different kinds of pressure-sensitive adhesive layers, wherein one pressure-sensitive adhesive layer (A) is constituted by a pressure-sensitive adhesive having a modulus at 50% elongation of 68,650 to 117,680 Pa and a modulus at 200% elongation of 147,100 to 245,170 Pa and another pressure-sensitive adhesive layer (B) is constituted by a pressure-sensitive adhesive having a modulus at 50% elongation of 19,610 to 68,650 Pa and a modulus at 200% elongation of 68,650 to 147,100 Pa. The pressure-sensitive adhesive tape has strong adhesion and suitable releasable properties. Use of such a tape in disposable diapers suppresses generation of discordant peeling sounds.
