Hermetic packaging makes pharmaceutical products safe

Hermetic packages protect pharmaceutical products from external influences like humidity, oxygen and light. The horizontal flow wrapping machine Sigpack HML allows products such as blow-fill-seal (BFS) vial cards, blisters and various medical technology products including pens and inhalers to be reliably hermetically packaged.

Flexibility in the packaging process
Due to its compact size, the machine can be optimally employed even where space is limited. It not only can seamlessly be integrated into complete packaging lines, it is also suited as an excellent stand-alone solution. This means that pharmaceutical manufacturers benefit from even greater flexibility in the packaging process.

The Sigpack HML is suitable for the production of both small and large batches. Depending on the desired output volume, the film reels can be changed either manually during short machine stops or with the help of a splicer. The fully automatic splicer connects the old and new film to avoid disturbances, such as at the film former.

Safe product processing
Products are delivered to the flow-wrapping machine via a transport chain. The transverse and longitudinal film sealing uses the proven long dwell heat-sealing technology. This ensures an extra-long sealing time, resulting in guaranteed tightly sealed packages, which means optimal protection for pharmaceutical products.

The sealing rolls used for horizontal wrapping can be opened from both sides. This prevents the film from coming into contact with the heated sealing rolls, and from being damaged during machine downtime. For particularly temperature-sensitive products, the cover plates at the sealing station can be cooled. As an alternative, the Sigpack HML is also available with ultrasonic sealing, allowing pharmaceutical manufacturers to gently package heat-sensitive products.

Options for highest product Quality
Upon request, the Sigpack HML can be equipped with options for additional product protection, such as the “no gap no seal” function. This is especially used for product piles in blister or BFS packages, which is checked once again shortly before it reaches the cross sealing. If the pile is not in the correct position, the cross sealing stops. It will thus avoid product rejection or damaged sealing jaws. The optional MAP module (Modified Atmosphere Packaging) offers optimal product stability by removing residual oxygen from the hermetic packages. Sensors precisely monitor and regulate the gas content of the packages.
