In the method for producing a polyolefin-based structure of the present invention, a polyolefin-based structure is produced by using a molding machine 10 from a mixed material of a polyolefin (A), an acid-modified polyolefin (B), and a gas barrier resin (C) under the following conditions. body. The molding machine 10 includes a uniaxial extruder 11, a die 12, and an adapter 13 for conveying the mixed raw material from the uniaxial extruder 11 to the die 12. Am+10°C≦T1≦Cm-10°C (1) Cm-30°C≦T2≦Cm+30°C (2) Cm-10°C≦T3≦Cm+50°C (3) Cm-30°C≦T4≦Cm+30°C (4) T1 is The cylinder temperature of the supply unit 21A and the compression unit 21B, T2 is the cylinder temperature of the measuring unit 21C, T3 is the temperature of the adapter 13, T4 is the temperature of the die, and Am is the melting point of the component (A); Cm is ( C) The melting point of the ingredients. |
