The requirements for the packaging of sterile parenteral nutrition solutions depend largely on the type of solution, sterilization method and specific barrier properties required.
Solmed EVA is used for the storage of lypophilic solutions, an application area where the use of PVC is limited.
Solmed Medipak EVA tubular film is available in a clear and a ribbed version. A special surface embossing on the outside of the tubular film reduces the sticking and blocking effect, and facilitates its use on automated welding machines. Special Medituub EVA and coextruded PVC/EVA Medituub are available to ensure a proper connection with the bag ports. Parenteral nutrition solutions containing amino acids and vitamins require high barriers for oxygen and UV light. Several multilayer Solmed films offer these barrier functions and excellent cold temperature resistance. The coextruded Medipak UVO tubular film contains an EVA fluid contact layer, is high frequency weldable and the film is suitable for ETO and gamma sterilization. The Solmed BF-series laminated cast barrier films are available in a width up to 1.3 meters. Many parenteral nutrition solutions are steam sterilized at 121˚C and contain components, such as glucose, lipids and amino acids, which must be stored seperately. These applications require steam sterilizable multicompartment bags with peelable seal, which can be manufactured from the Solmed Mediflex and Infuflex polyolefin films. In combination with Solmed Tubeflex tubing and Granuflex based ports, a complete polyolefin system can be realized. Enteral nutrition applications require reliable and cost effective packaging materials. Various Solmed materials are available for the large diversity in enteral feeding products:
- Solmed Vinylfoil and calendered films, cost effective and available in clear and white
- Solmed EVA cast film and Medipak EVA tubular film, often used for longer shelf-life storage of fatty solutions
