  • Method of producing a medical fluid container from flexible plastic material, film tubing as intermediate product for a fluid container of this type and medical container produced according to a method of this type
    Patent number: 8679601
    Abstract: A medical fluid container of a flexible plastic material is produced as follows: at first, a plastic compound is produced from a heterogeneous mixture of a first, lower-viscosity raw polymer component having a first melt viscosity and a second, higher-viscosity raw polymer component having a second melt viscosity which is greater than the first melt viscosity. Then the plastic compound is extruded. The extrudate is confectioned. Finally, the confectioned extrudate is sealed to form the finished fluid container. A film tubing may serve as intermediate product for the medical container. The medical container or the film tubing thus produced has surface structures with a typical average size of 15 to 200 ?m. The production method requires little effort while fulfilling demanding requirements with respect to the stability of the produced fluid container.
