20090152095 | EASY-TO-TEAR STRETCHED ALIPHATIC POLYESTER FILM - The easy-to-tear stretched aliphatic polyester film of the present invention is characterized in that the edge tear strength in the longitudinal direction and the transverse direction is not more than 22 N. The easy-to-tear stretched aliphatic polyester film of the present invention is produced by a method of irradiation of actinic rays on an aliphatic polyester film or a method of film-forming a film obtained by laminating aliphatic polyesters having different melting points in three layers of A/B/A under particular film-forming conditions. | 06-18-2009 |
20090324884 | Polyamide Based Mixed Resin Laminated Film Roll and a Process for Producing the Same - The present invention provides a polyamide based mixed resin laminated film roll formed by winding up a polyamide based mixed resin laminated film comprising a plurality of polyamide mixed resin sheets stacked on top of each other. A first sample cutout portion is provided within 2 m from the winding end of film, and a final sample cutout portion is provided within 2 m from the winding start of film. The roll is regulated so that, when sample cutout portions are provided at intervals of about 100 m from the first sample cutout portion, for all samples cutout from the cutout portions, the elastomer content, tensile modulus of elasticity, thickness unevenness in the longitudinal direction and other properties fall within a predetermined variation range. | 12-31-2009 |

20080213577 | Easy Tear Biaxially Stretched Polyester Based Film - The present invention provides an easy-to-tear biaxially-stretched polyester film having easy cut property and adhesiveness, as well as superior properties of polyester film, such as heat resistance, moisture-proof property, transparency, aroma retention and the like. | 09-04-2008 |
20080254259 | Polyamide Based Mixed Resin Film Roll And Process For Producing The Same - The problem to be solved by the present invention is to provide a biaxially oriented polyamide based mixed resin film roll with which bag forming processing by lamination is able to be performed smoothly and with high yield ratio and at the same time with which packages free of S-shaped curls can be obtained efficiently. A solution for the problem concerns the polyamide based mixed resin film roll of the present invention which includes a first sample cutout portion within 2 m from the winding end of film and a final cutout portion within 2 m from the winding start of film, and when a sample cutout portion is set up in approximately every 100 m from the first sample cutout portion, in all samples cut out from each of the cutout portions, physical properties such as elastomer content, elastic modulus in tension, boiling water shrinkage percentage and refraction index in the thickness direction are adjusted to be within a predetermined range of variation range. | 10-16-2008 |
20090065979 | Process for Producing Polyamide-Based Resin Film Roll - The present invention provides a process for production of a polyamide based resin film roll comprising a step of melt-extruding and cooling wherein polyamide based resin is melt-extruded and cooled in a sheet form onto a mobile cooling material surface to obtain an unstretched sheet; a step of biaxial stretching wherein an unstretched sheet is stretched biaxially in the longitudinal direction and the transverse direction; and a step of winding up the biaxially stretched film that is biaxially stretched in a form of roll. Then, in the step of melt-extruding and cooling polyamide based resin onto a mobile cooling material surface, corona discharge in a streamer corona state is performed between an electrode applied with high DC voltage and the polyamide based resin sheet in the melted state, and sufficient electric charges that enable the polyamide based resin sheet in the melted state to come in close contact with the mobile cooling material surface are imparted. | 03-12-2009 |
