Abstract: The present disclosure is directed to provide a multilayer film for use in an air bag, which provides sufficient adhesiveness and blocking tendency in a well-balanced manner. The multilayer film for use in an air bag according to the present disclosure includes an adhesive layer and an outer layer. The adhesive layer includes a resin having a glass transition temperature from 0° C. to 80° C. and a melting point from 100° C. to 160° C. The outer layer includes a resin having a melting point higher than the melting point of the resin included in the adhesive layer by 20° C. or higher. Further, an air bag according to the present disclosure includes a synthetic fiber fabric and the aforementioned multilayer film for use in an air bag, in which the adhesive layer in multilayer film is laminated with the synthetic fiber fabric.

Abstract: A molded article for packaging of the present invention is obtained by molding a laminated film having a barrier layer, and including an opening with an opening area A, and an inner surface with a surface area B constituting a space for housing a content, a ratio B/A of the surface area B of the inner surface to the opening area A of the opening is 1.2 or more to 7 or less, and in a case where a maximum thickness of the molded article is 300 ?m or more, a ratio TMIN/TMAX of a minimum thickness TMIN to a maximum thickness TMAX of the barrier layer is 0.2 or more, and in a case where the maximum thickness of the molded article is less than 300 ?m, a ratio TMIN/TMAX of a minimum thickness TMIN to a maximum thickness TMAX of the barrier layer is 0.12 or more.

Abstract: The present invention provides a novel vinylidene chloride resin composition that excels in thermal stability and enables the extrusion of films at a high extrusion rate; a biaxially stretched film that is manufactured from the vinylidene chloride resin composition and excels in barrier properties and transparency; and a multilayer film including the stretched film. The copolymer resin composition contains a vinylidene chloride-methyl acrylate copolymer resin that has a content ratio of methyl acrylate component of no less than 4 wt. % and no more than 6 wt. % and a weight-average molecular weight, determined by gel permeation chromatography, of no less than 60,000 and no more than 80,000 and contains as additives predetermined volumes of: (a) an epoxidized vegetable oil; (b) 2,6-di-tert-butyl-4-methylphenol; (c) dl-?-tocopherol; (d) a thiodifatty acid dialkyl ester; and (e) an ethylenediaminetetraacetic acid salt.
