Individual Cooling System For Medication Packaging For Bayer Schering Pharma

By Dr. Egon Hüfner, Segment Management Cooling Systems, Bürkert Fluid Control Systems

When tablets are packaged in blisters, the plastic film must be the right temperature at the right moment: which is no easy task at an output of up to 1,300 blisters per minute. A customer-specific combination for proportional valve, temperature sensor and controller master is using the regulation of cooling water flow. If needed, machine developers can implement 13 parallel-working temperature control circuits.

Blister packs have replaced plastic bottles as the most-sold type of medication packaging worldwide. Advantages such as acceptance of medication by patients, higher flexibility in logistics, sterility through individual packaging, child safety, and marketing attractiveness will expand their distribution as packaging for pharmaceutical products. However, the manufacturing of blister packs represents a critical process for companies that package medications, as these packs have a relatively complex structure consisting of two or more components. A constant and repeatable blister size is also necessary.
