The invention provides a container mouth manufacturing method and belongs to the technical field of packaging. It solves the problems of high production cost and insufficient barrier performance of conventional container mouths. The method adopts multi-layer co-extrusion to produce tubular multi-layer plastic parisons through an extruder. The parison is placed in a blow molding die and blow-molded into a single integral component with multiple container mouths arranged along one axis. Finally, individual container mouths are cut from the blow-molded part. The produced multi-layer container mouths feature excellent barrier properties. The one-time blow molding of multiple container mouths ensures high production efficiency, reduces waste output and effectively controls manufacturing costs. Blow molding achieves uniform wall thickness and lower material consumption, further cutting production expenses.
