DIRECT BLOW-MOLDED CONTAINER MANUFACTURING METHOD AND PACKAGE

摘要

Provided is a method for manufacturing a direct blow-molded container exhibiting superior barrier performance for fuel, chemicals, and gases such as oxygen. The direct-blow molded container is free of deformation and practical. The method for manufacturing a direct blow-molded container, said direct blow-molded container having a meta-xylylene group-containing polyamide (C) dispersed in layers within a polyolefin (A), uses a die provided with: a die body having a flow hole through which molten resin discharged from an extruder flows, and a cylindrical hollow section having a downward-facing opening, the flow hole opening into the top of the cylindrical hollow section; a mandrel with a front-tip part on the upper side, and which is positioned in the hollow section so that the front-tip part faces toward the opening at the end of the flow hole; and a support section that holds the mandrel inside the hollow section of the die body, and that is formed in the passage clearance between the hollow section of the die body and the mandrel so that the passage clearance forms a resin flow path.
