A method reduces the microbiological loading of container products made at least partially of at least one plastic material. As part of a first production process, a plastic granulate () is fed to an extruder device (), which melts the granulate (). As part of a subsequent production process, the melted granulate is forwarded onto a blow-molding, filling and sealing machine for obtaining the respective container product. At least in parts of the first production process, the plastic material undergoes at least one of the following treatment steps: high-energy radiation and/or plasma treatment and/or a gas having a sterilizing effect.

Method for reducing the microbiological loading of container products

A device for reducing the microbiological contaminants of container products made predominantly of plastics materials feeds a plastics granulate to an extruder assembly () that melts the granulate. The granulate is subsequently supplied to a form-fill-seal machine for producing a container product. A guide assembly () guides the plasticated plastic material from the extruder assembly () to the machine. At least one guide assembly () has at least one flow or channel guide () for the melted plastics material, so that microbiological contaminants are guided predominantly into the interior of the wall of the polymeric tube that interior is enclosed by regions of the plastic material that are less contaminated.
