摘要： [PROBLEMS] To provide a heat-shrinkable polyester film which little causes printing omission in spite of its being produced by using a recycled material such as PET bottle and which satisfies the requirements of application of PET Bottle Recycling Recommendation Mark. [MEANS FOR SOLVING PROBLEMS] A heat-shrinkable polyester film produced either by laminating a substrate layer containing recycled PET bottle material with a layer free from recycled PET bottle material on at least one side and printing the layer free from recycled PET bottle material or by laminating a substrate layer containing 45 to 80 wt% of recycled PET bottle material with layers made mainly of a noncrystalline raw material on the both sides, in which when the film is dipped in water at 80˚C for 10 seconds and drawn up, the heat shrinkage in the main-shrinkage direction is 30% or above and the heat shrinkage in the direction perpendicular to the main-shrinkage direction is 10% or below and which is stretched at least uniaxially.

摘要： A heat-sealable layered polypropylene resin film which has a heat-sealing strength and heat-sealing energy sufficient to package weighty articles such as vegetables and fruits and has satisfactory stiffness; and a package obtained with the film. The heat-sealable polypropylene resin film comprises a laminate of three or more layers comprising a base layer made of a crystalline polypropylene resin, an interlayer, and a fusion-bondable layer having a melting point of 150°C or lower, and is characterized in that the product of tensile moduli (GPa) of the film as measured in directions perpendicular to each other is in the range of 3.1 to 6.0 (GPa) and that the sealing energy of the film sealed so as to have a heat-sealing strength of 8 N/15 mm or higher is 11 N.cm/15 mm or higher.

摘要： [PROBLEMS] To provide a polyamide mixed resin laminated film roll that can smoothly conduct bag making by lamination at a high yield and can efficiently provide a package free from S-shaped curling. [MEANS FOR SOLVING PROBLEMS] The polyamide mixed resin laminated film roll is a roll obtained by winding a polyamide mixed resin laminated film comprising a plurality of polyamide mixed rein sheets stacked on top of each other. A first sample taken-off part is provided within 2 m from the end of winding of the film, and a final sample taken-off part is provided within 2 m from the start of winding of the film. The roll is regulated so that, when sample taken-off parts are provided at intervals of about 100 m from the first sample taken-off part, for all samples taken off from the taken-off parts, the elastomer content, tensile modulus of elasticity, thickness unevenness in the longitudinal direct and other properties fall within a predetermined variation range.

摘要： A process for efficiently producing a biaxially oriented polyamide-based resin film roll capable of bag-making processing through laminating smoothly with high yield. There is provided a process for producing a polyamide-based resin film roll, comprising the melting extruding cooling step of conducting melt extrusion of a polyamide-based resin in the form of a sheet and cooling of the extrudate on the surface of a moving cooling body to thereby obtain an unoriented sheet; the biaxial drawing step of biaxially drawing the unoriented sheet in the lengthwise direction and lateral direction; and the take-up step of winding in roll form the biaxially oriented film resulting from the biaxial drawing. In the melting extruding cooling step, during the melt extrusion of the polyamide-based resin and cooling of the extrudate on the surface of the moving cooling body, streamer corona discharge is carried out between an electrode having a direct current high voltage applied thereto and a molten polyamide-based resin sheet to thereby realize application of satisfactory charges for bringing the molten polyamide-based resin sheet into close contact with the surface of the moving cooling body.
