▎ 摘  要

NOVELTY - The hose has a core tube (20) having a conveying space (21) for receiving and guiding a molten polymer. A heating device (26) maintains the molten polymer in the molten state. Multiple layers (22) are arranged around the core tube and on top of one another. The core tube or multiple layers comprises graphene-based material or pyrolytic graphite or silicon oxide. The gas barrier layer is provided with graphene-based material or pyrolytic graphite or silicon oxide. The heating layer is a combined gas barrier and heating layer. The heating device comprises an electrical energy supply unit. The core tube comprises a food grade material. USE - Hose for molding apparatus for molding plastic components, such as opening and/or outpouring devices, used in packaging machine for forming composite packages (all claimed). ADVANTAGE - The invention improves the known hoses so as to increase the lifetime of the hoses. It reduces the maintenance work that is needed to exchange the hose. DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for a molding apparatus for molding plastic component onto multilayer packaging material. DESCRIPTION OF DRAWING(S) - The drawing shows a schematic view of the hose for molding apparatus for molding plastic components. 20Core tube 21Conveying space 22Layer 24Reinforcement layer 26Heating device
