Abstract
A manufacturing method for manufacturing a biodegradable resin container includes at least: an injection molding process of injection molding a preform made of a biodegradable resin in an injection molding mold; a temperature adjustment process of adjusting a temperature of the preform in a temperature adjustment mold; and a blow molding process of manufacturing a container by blow molding the preform after temperature adjustment in a blow mold, in which a temperature of the injection molding mold is set to 40° C. or lower.
Claims11
A manufacturing method for manufacturing a biodegradable resin container, the manufacturing method comprising at least:
- an injection molding process of injection molding a preform made of a biodegradable resin in an injection molding mold;
- a temperature adjustment process of adjusting a temperature of the preform in a temperature adjustment mold;
- and
- a blow molding process of manufacturing a container by blow molding the preform after temperature adjustment in a blow mold,
- wherein a temperature of the injection molding mold is set to 40° C. or lower.
A manufacturing method for manufacturing a biodegradable resin container, the manufacturing method comprising at least:
- an injection molding process of injection molding a preform made of a biodegradable resin in an injection molding mold;
- a temperature adjustment process of adjusting a temperature of the preform in a temperature adjustment mold;
- and
- a blow molding process of manufacturing a container by blow molding the preform after temperature adjustment in a blow mold,
- wherein, in the temperature adjustment process, a temperature of inner and outer skin layers of the preform is heated to a heating temperature which is a melting point of the biodegradable resin or close to the melting point.
