bottelpack® packaging systems are designed individually to meet specific customers' needs. BFS technology offers the huge benefit of enabling the entire process, which includes manufacturing a container, filling it with the product and then sealing it, to be completed in one short cycle using only one machine. Firstly, the sterile, pyrogen-free bottles or ampules are blow molded from extruded PE or PP in water-cooled molds. Immediately afterwards, the containers are filled with the sterile product in aseptic conditions and then hermetically sealed.he process guarantees extremely high levels of reliability and product safety and also offers a number of other benefits for users. For example, molding the closure and applying a code can be integrated into the process. The key features of this technology are its almost complete exclusion of foreign particles and its neutrality towards the product in the containers.
