Abstract
The production method for a polyolefin-based structure of the present invention produces a polyolefin-based structure from a mixed source material containing a polyolefin (A), an acid-modified polyolefin (B) and a gas barrier resin (C) using a molding machine, under the condition mentioned below. The molding machineis equipped with a single-screw extruder, a die head, and an adaptorfor feeding the mixed source material from the single-screw extruderto the die head. Am+10° C.≤T≤Cm−10° C. (1), Cm−30° C.≤T≤Cm+30° C. (2), Cm−10° C.≤T≤Cm+50° C. (3), Cm−30° C.≤T≤Cm+30° C. (4). Tis a cylinder temperature in a section corresponding to a supply zoneA and a compression zoneB, Tis a cylinder temperature in a section corresponding to a metering zoneC, Tis a temperature of an adaptor, Tis a temperature of a die head, Am is the melting point of the component (A), and Cm is the melting point of the component (C).
