Overview
Why aseptic filling places special demands
Aseptic filling places the highest demands on the cleanliness and integrity of all process components. Our GMP-compliant primary packaging materials made from polyethylene are specially developed for direct contact with sensitive pharmaceutical active ingredients. Through our manufacturing in cleanrooms up to ISO Class 5, we guarantee low-particle and microbiologically controlled packaging solutions that can be seamlessly integrated into your validated filling lines and maximise product safety. In aseptic filling, the aim is to fill a sterile product into a sterile container under sterile conditions in order to rule out microbial contamination. Every component that comes into contact with the product must itself be sterile and free from particles. Our primary packaging materials are therefore not just a shell, but an active part of the containment concept.
Critical requirements in aseptic filling
Particle control and sterility
Every particle poses a contamination risk. Our primary packaging materials are manufactured in cleanrooms of ISO classes 5, 7 and 8. They are suitable for common sterilisation methods such as gamma irradiation.
Material compatibility
The packaging must not enter into any unwanted interactions with the active ingredient. We use only qualified pharmaceutical-grade materials and provide extensive data on extractables and leachables.
Seamless integration
Our pouches and films must fit perfectly into highly automated and validated filling lines. We guarantee precise dimensional accuracy and consistent material properties.
