Title:
MULTI-LAYER BLOWN FILM MOLDING MACHINE AND METHOD OF MOLDING MULTI-LAYER BLOWN FILM
Document Type and Number:
WIPO Patent Application WO/2005/046970
Kind Code:
A1
Abstract:
A multi-layer blown film molding machine, comprising an adapter installed to supply multiple types of resins, a molding die installed on the axial downstream side of the adapter, and a temperature control mechanism. The multiple types of molten resins are individually supplied to the molding die through the adopter. The molding die further comprises a body, a laminate of a plurality of single layer thin-film molding dies axially disposed in the body and generating the thin-film of the corresponding resin among the multiple types of molten resins and a first annular passage formed between the body and the laminate. A multi-layer thin-film formed of the plurality of thin-films laminated on each other is outputted as a multi-layer thin-film annular film through the first annular passage, and the temperature control mechanism independently controls the temperatures of the plurality of single layer thin-film molding dies.
