Abstract: A resin composition includes a biodegradable resin (A), a polyolefin resin (B) and a dispersing agent (C), which has a sea-isle structure in which the biodegradable resin (A) is dispersed as isles in the polyolefin resin (B) existing as a sea component wherein the average dispersed particle size of the biodegradable resin (A) is 1 nm to 1000 nm.

Abstract: The present invention relates to a gas barrier film where a polyurethane resin layer and an inorganic layer are disposed in this order from a polyester resin film side on at least one surface of a polyester resin film, wherein the polyurethane resin constituting said polyurethane resin layer is a resin containing a skeleton represented by the following formula (1) and/or the following formula (2). The present invention provides a gas barrier film having excellent oxygen insulation and water vapor insulation.

Abstract: A biaxially oriented polyester film includes at least three polyester resin layers A1/B/A2, and has a melting point in the range of 246 to 270° C. The major component of the layers A1 and A2 is polyethylene terephthalate and the stress at 100% elongation in the film's longitudinal direction and width direction at 150° C. and 200° C. meets the following equations: 2?(F100MD+F100TD)?100 and 1?F100TD?60. The film has a high dimensional stability at high temperatures to permit uniform metal deposition, suffers little change in appearance during thermoforming, and serves for easy production of formed parts that closely meet the shape of the die when subjected to low-stress forming.

Abstract: A vapor deposition film has a vapor deposition layer composed of a metal or an inorganic oxide formed on at least one side of a resin layer (A) which is composed of a resin composition (1). The resin composition (1) is a polyglycol acid containing not less than 70% by mole of a specific structure (a structure represented by formula (1)) as a repeating unit. The surface on which the vapor deposition layer is deposited has a center line average roughness of 5-50 nm. The vapor deposition film has excellent gas barrier properties, excellent workability and decomposition resistance sufficient for practical use.
