Provided are: a molded product in which the strength anisotropy between the MD direction and the TD direction is small; and a processed article of the molded product. A molded product (10) contains a glycolate-based polymer and multiple fibers (11). The fibers (11) include, at a specific ratio, fibers aligned in the MD direction and fibers aligned in a direction along a tangent line of a concentric circle in a cross section orthogonal to the MD direction.
This molded body is composed of a composition including a glycolic acid polymer, a plasticizer, and a degradation promoter. The absolute value of the difference between the Fedors solubility parameter of the plasticizer and the Fedors solubility parameter of the glycolic acid polymer is 6 (J/cm3)1/2 or lower. The plasticizer content of the composition is 10-50 mass%.
Provided are: a vinylidene chloride-based resin film which, when a content is filled and packaged in the vinylidene chloride-based resin film, makes it possible to eliminate the shortage of a color retention period for the content before and after a retorting treatment; and a filled/packaged product which is produced using the vinylidene chloride-based resin film. The vinylidene chloride-based resin film according to the present invention comprises a vinylidene chloride-based resin, and is configured such that, when a content containing 20% by mass of a lipid is filled and packed in the vinylidene chloride-based resin film which is bundled at both length-direction ends thereof so as to form a tubular shape to thereby produce a filled/packaged product, then the filled/packaged product is subjected to sterilization by pressurization and heating at 0.2 MPa in hot water having a temperature of 120°C for 10 minutes, the oxygen transmission rate of the vinylidene chloride-based resin film before the sterilization by pressurization and heating in terms of the thickness of 40 μm is defined as A (cm3/m2･day･atm), and the oxygen transmission rate of the vinylidene chloride-based resin film after the sterilization by pressurization and heating in terms of the thickness of 40 μm is defined as B (cm3/m2･day･atm), the rate of change in the oxygen transmission rate which is determined in accordance with the formula: (B-A)/A×100 is 35.0% or less.
