Abstract
A resin composition comprising at least one copolymer (A) selected from an ethylene/(meth)acrylic acid copolymer (A1) and an ethylene/(meth)acrylic acid/(meth)acrylic acid ester copolymer (A2), and a polyethylene (B), wherein when the total amount of (A) and (B) in the resin composition is set to be 100% by weight, the content of (A) is less than 100 to 46% by weight, the content of (B) is in excess of 0 but not larger than 54% by weight, and (A) contains 0.1 to 5% by weight of a (meth)acrylic acid unit. There are thus provided a resin composition comprising an ethylene/(meth)acrylic acid bicopolymer or an ethylene/(meth)acrylic acid/(meth)acrylic acid ester tercopolymer and a polyethylene, as well as a film or a sheet made from the resin or the resin composition, and a laminate thereof featuring high-speed workability in the extrusion lamination working, particularly excellent adhesiveness to the polar base materials, adhering little in the extrusion-molding machine, without requiring the use of a purging agent and/or a purging resin at the time of changing the kind of the resin or changing the colored lot of the resin, or requiring the purging agent and/or the purging resin in conspicuously small amounts if they are used.
