发明名称 Multilayered structure
摘要 <p>The present invention provides a multilayered structure where an A layer made of an ethylene-vinyl alcohol copolymer resin (A) and a C layer made of a polypropylene resin (C) are laminated via a B layer made of an adhesive resin (B). The ethylene content of the ethylene-vinyl alcohol copolymer resin (A) is 20 to 60 mol%, and the saponification degree of the resin (A) is at least 90%. The melt flow rate (MFR) of the polypropylene resin (C) at 230 DEG C under a load of 2160g is in the range from 0.1 to 100g/10min, and the stereoregularity index M5­ of the polypropylene resin (C) is at least 0.950. Such a multilayered structure has excellent gas barrier properties and moldability.</p>
