摘要： A biaxially stretched heat-shrinkable laminated film is disclosed which possesses good heat-shrinkability, excellent melt hole resistance and heat-resistant sealing property (the heat resistance of a seal portion), and highly satisfactory cold resistance, retains transparency even after shrinkage, and serves advantageously as a wrap for packaging foodstuffs. The laminated film is provided as an oxygen barrier layer with a layer of a mixture of vinylidene chloride resin and a low melting point polyamide resin having a crystalline melting point of not higher than 210.degree. C. This mixed resin has been cross-linked by applying the electron beam to the laminate in a dosage in the range of 1 to 12 megarads. The laminated film exhibits a heat shrinkage percentage of not less than 15% at 90.degree. C. and excels in gas barrier property.

摘要： Disclosed herein are a resin composition comprising 5 to 95% by weight of a vinylidene chloride resin and 5 to 95% by weight of a polyamide resin having a low crystalline melting point of not higher than 210.degree. C. and a molded product of said resin composition.The molded product of the present invention shows a molded product excellent in gas-barrier property and impact strength at low temperature, particularly a film, sheet or container.Among the resin compositions of the present invention, since the composition having 60 to 95% by weight of vinylidene chloride resin is particularly rich in gas-barrier property, it is suitable for packaging foods, and since the composition having more than 40% by weight and not more than 95% by weight of polyamide resin is excellent particularly in impact strength at low temperature, it is suitable as the packaging material for use at an extremely low temperature. Moreover, the gas-barrier property and the transparency of the latter molded product which is rich in polyamide resin can be improved by stretching the product so that the dispersed particle of vinylidene chloride resin is made to be flat.

摘要： A water-insoluble, nonionic water-absorptive polyurethane fiber that combines the properties of high water absorptivity and excellent physical strength is produced by extrusion from a thermoplastic polyurethane resin composition at a temperature higher than its melting point. The thermoplastic polyurethane resin composition, which has a water absorption rate within the range of 200-3,000%, is obtained by reacting a polyisocyanate compound, a water-soluble polyalkylene ether polyol having a weight-average molecular weight of 2,000-13,000 and a chain extender at an equivalent ratio (R ratio) between the equivalent number of NCO groups and the equivalent number of OH groups in the range of 1.0 to 1.8. Also provided is a method of producing the water-absorptive polyurethane fiber.

摘要： The present invention provides a laminated film including at least two layers of an outer layer having a printed portion on a surface and an inner layer subjected to an antifogging treatment in which principal resin comprising a solid content of the printed portion is made of chlorinated polypropylene-based resin or urethane-based resin. This antifog laminated film hardly degrades in an antifogging property even when the antifog laminated film subjected to printing on the outer layer of a surface subjected to the antifogging treatment and the printed surface are strongly brought into contact with each other due to an operation of winding the film into a roll or the like.
