METHOD OF MAKING VESSEL DIRECT BLOW FORMING AND PACKAGE Russian patent published in 2016 - IPC B29C49/04 B29C47/20 B29C49/42 

FIELD: packaging industry.

SUBSTANCE: invention relates to method of practical vessel for direct blow molding producing which has excellent barrier properties towards fuel, chemical compounds, various gases, including oxygen. Method of container for blow molding producing containing meta-xylene group of polyamide (C) which is dispersed and layered in polyolefin (A). Method involves usage of die which has a housing with a channel for flow in which molten polymer flows extruded from the extruder and cylindrical cavity, which has a hole in the lower side and a flow channel in the upper side. Mandrel has a tip in the upper side which points to the hole at the end of the flow channel. Flow path gap is formed between the housing cavity of die and mandrel. Flow path gap forms the flow path of the polymer and a support part formed the flow path gap. Support retains the mandrel inside the housing of the die.

EFFECT: technical result achieved when using the method is obtaining quality multilayer containers at facilities for production of single-layer containers.
