The method for producing a polyolefin structure of the invention produces a polyolefin structure under the following conditions from a mixed raw material of polyolefin (A), acid-modified polyolefin (B), and gas barrier resin (C) using a molding machine (10). The molding machine (10) is provided with a single-screw extruder (11), die head (12), and adapter (13) for sending the mixed raw material from the single-screw extruder (11) to the die head (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 feed unit (21A) and the compression unit (21B), T2 is the cylinder temperature of the metering unit (21C), T3 is the temperature of the adapter (13), T4 is the temperature of the die head, Am is the melting point of component (A), and Cm is the melting point of component (C). |
