In the embossing station, a code (e.g. batch no. expiry date) consisting of letters and/or numbers is embossed into the formed and sealed web by dies. Nowadays because of the track & trace requirement in pharmaceutical industry, this embossing station can be designed to equipped inkjet printer to spurts numbers, graphics or QR codes on the web side or the lidding side of the blister.
In the perforation station, the formed and sealed web can also be perforated between the individual pockets to allow them to be separated from the pack at the time of use. Conventionally, perforation and embossing remain in one station, but this will influence the clarity of each, for the high speed Blister Machine the influence will be more, so we recommend to add a perforation station, to separate the perforation from the embossing station, but this is optional not compulsory.
