PURPOSE:To obtain the title relatively inexpensive material having excellent retort resistance at high temperature, excellent flexibility, gel preventing properties and oil resistance by containing a specific copolymer polyamide mixed with nucleating agent as a layer. CONSTITUTION:The objective material containing a material obtained by blending a tridimensional polymer which comprises capronamide as a main constituent unit, is copolymerized with 10-50wt.% other two aliphatic polyamides and has 150-200 deg.C melting point with a nucleating agent, as a layer. For example, talc, mica, etc., are used as the nucleating agent. |
