The handy stick sacks become more and more popular, even in the pharmaceutical industry. Reasons for the rising popularity are obvious: Stick packs offer a safe packaging which is produced achieving a high output level, but consumes less packaging material compared to alternative pack styles. These are reasons for the pharmaceutical manufacturer Bright Future to opt for this packaging solution from Bosch.
Established in 1993, Bright Future Pharmaceutical Ltd. has become Hong Kong’s largest GMP-certified (Good Manufacturing Practice) supplier of pharmaceutical products. Until now, the company marketed penicillin powder packaged in sachets (flat pouches). Due to an increase in sales, a new packaging line was required achieving the appropriate production output. Bright Future decided for for the Sigpack RA/HCM and thereby for a new pack style: the stick pack. With an output level of 1000 stick packs per minute, Bright Future could not only reach its production objectives, but also lower the consumption of packaging material by shifting to another pack style. Additionally, patients benefit from the handy stick pack benefits the patients: The perforation ensures easy opening as well as fast and complete emptying of the package. Bright Future now markets its penicillin as a multipack containing six stick packs.
Primary and secondary packaging from one source
High dosing accuracy as well as proven sealing technology for primary packaging in combination with safe interface handling and a reliable secondary packaging are important success factors of a stick pack packaging line.
Primary packaging into stick packs is being executed by a ten-lane vertical stick pack machine Sigpack RA, while secondary packaging is realized via the horizontal flow wrapping machine Sigpack HCM, reaching an output level of up to 1000 stick packs packaged in 175 multipacks per minute.
Individually AC servo-controlled filling augers ensure the required dosing accuracy. The in-line weighing system controls the weight of each stick pack and regulates dosing at the machine via an integrated tendency control. This continuous adjustment ensures a consistently accurate filling process. Following the weighing procedure, the stick packs are counted, grouped and fed towards the Sigpack HCM flow wrapper. Each sales unit packaged on the Sigpack HCM consists of two stacks with three penicillin stick packs each in a flow wrap.
The cantilever design of the system completely separates process elements from drive units of the machine. Additionally, the ergonomic operating height improves operator access and allows for a direct view into the packaging process. “Format changes and infeed of packaging material can be realized fast and easily,” emphasizes Product Manager Frank Bühler. “Lifetime-lubricated components also contribute to the line’s hygienic design.”
The machine casing guarantees safety and contributes to noise protection at the same time. Below the product transport unit, the machine elements are fully visible for a facilitated line clearance. The crucial operating functions such as Start, Stop and Emergency Stop are integrated on the line’s front. All other functions are accessible via a pivoting Human Machine Interface (HMI) with 12″ color touchscreen.
GMP-compliant design meets customer expectations
Since its foundation, Bright Future has been committed to the promotion of public health. For the company, the quality of its pharmaceutical products is of highest priority. In manufacturing, Bright Future also strictly follows GMP and GLP (Good Laboratory Practice) principles. The line’s GMP-compliant construction therefore meets a further customer demand.
The new Bosch line enables Bright Future to package its penicillin powder using less material while increasing efficiency. Simultaneously, the easy-to-open stick packs enhance convenience for the end user. “To supply our global customer base with reliable pharmaceuticals and health products we were looking for a competent partner offering high-quality equipment. With Bosch Packaging Systems, we found such a partner,” says Dr Susanna Wan, Purchasing & Development Manager at Bright Future.
