Portions of sensitive single-use liquids and pastes are traditionally packaged using the blow-fill-seal method (BFS). However, in general this is complex and inflexible. When it comes to the manufacturing of aseptic packages, sterile blisters from Rohrer provide an innovative, cost-effective, and environmentally friendly alternative to the traditional method. This sterile blister works as the economical alternative to blow-fill-seal. Single-dose packaging can be used in numerous applications and is particularly suitable for medication which comes in the form of drops or ointments (such as eye drops, eye creams, nose drops, cough drops), as well as cream or gel cosmetics.

The single-use format is not just ideal for medication which has to be used directly after opening for sterility and preservability reasons – it is also perfect to provide test samples during promotions. Compared to the BFS method, the blister-based technology used by Rohrer for sterile packaging, such as the process for the aseptic filling of eye drops, is considerably more flexible and economical. It opens the possibility to process several sterile products on one system and is even economical for small quantities. There is also a great degree of freedom in choosing the color and print style for the packaging design. What's more, a variety of dimensions and shapes are possible. Aluminum blisters are generally used due to their high barrier characteristics; however, plastic can also be used for special applications or for aesthetic reasons. In contrast to BFS containers, the product is protected against external effects such as light or oxygen, as well as evaporation in a sterile aluminum blister – the content therefore remains stable for a longer period of time. An optional spout offers added versatility when it comes to the administration options.
