Abstract: An object of this invention is to provide a resin composition usable as a modifier with which the brittleness of a plastic material including a plurality of resins, such as a laminate of different kinds of materials collected for recycling, can be overcome and the impact resistance and elongation at break can be enhanced. Provided is a resin composition (A) including the following components (1) and (2): (1) a composition (a1) including at least two kinds of ethylene-vinyl acetate copolymers having different vinyl acetate contents; and (2) a copolymer (a2) that is at least one copolymer selected from an ethylene-acrylic acid copolymer and an ethylene-methacrylic acid copolymer.

Abstract: Disclosed are a separator for lipid bilayer membrane formation capable of forming a lipid bilayer membrane with excellent properties, wherein the separator for lipid bilayer membrane formation has sufficient mechanical strength and can be easily manufactured in a large scale by using a general-purpose machine without need of using an expensive machine, and a method of producing the separator. The separator for lipid bilayer membrane formation includes a thin film having one or more through holes and made of a resin capable of being wet-etched, and reinforcing layers covering both surfaces of the thin film and made of a resin capable of being wet-etched. The reinforcing layers cover the whole area of the thin film, except for the through holes and the peripheries thereof, and each through hole has a tapered cross-sectional shape.
