We are currently the only Canadian company offering in-line valve application combined with digital printing for flexible packaging ,
Coffee packaging needs to vent these gases to prevent pressure build-up and ultimately bursting of the bag . At the same time , non-gas-proof packaging is not an option , because roasted coffee oxidizes upon contact with oxygen , causing staleness and loss of aroma . Airtight bags equipped with degassing valves solve this problem and ensure a significantly extended shelf life of the packaged coffee of up to 30 months . This enables roasters to sell their product not only locally and within a short time after roasting but also ship it without worrying about loss of quality .
Matching sustainability standards
For Rootree , the search for a new valve application system and a supplier started at the beginning of 2022 . Naturally , Rootree was looking for a higher output than the previous solution could deliver , but there were other boxes to tick , as well . Pia Simran
Thanks to operator training from Syntegon specialists , operators at Rootree were able to perform a smooth start-up of the new , userfriendly CVA Valve Applicator .
Marco Weritz , Sales Engineer for Valve Applicators and Valves
remembers : “ Our sustainability standards ruled many companies out . In fact , Syntegon was the only company we came across that had a clear roadmap towards even more sustainable valve solutions .” The CVA 2000 VIS Internal Valve Applicator that Rootree chose for their production applies valves using ultrasonic sealing . This technology enables the machine to process the more environmentally friendly monomaterials of Rootree ’ s recyclable and compostable product lines . In contrast , traditional methods of sealing , such as heat sealing , are not possible with mono-materials .
Quick results and seamless integration
While Syntegon also offers complete production lines including valve application , the CVA 2000 VIS “ retrofit ” valve applicator was the best fit in Rootree ’ s case . It can be seamlessly integrated in Syntegon ’ s lines as well as existing equipment from other manufacturers – making for a more cost-effective solution . In September 2022 , the installation process at Rootree ’ s production site went fast and smoothly . Syntegon had custom-engineered a solution to integrate and mount the CVA 2000 VIS valve applicator on the existing pouch making machine . This turned the formerly semiautomated line into a much more efficient , fully automated one . Now , the stand-up or pillow pouches and the 3-side or quad-seal bags
For Pia Simran , Vice President of Product and Business Development and Phil St-Cyr , President & CEO of Rootree , the choice for Syntegon equipment proved the right one .
Rootree produces are automatically fed into the valve applicator , requiring no more manual labor . Installation was followed by calibration of the machine and operator training , executed by highly qualified Syntegon specialists . The Rootree staff was able to put the updated production line back to work after only two days of production stop .
Streamlining production Since then , the line has been producing valved bags reliably and much faster than before : 50 to 60 bags per minute , whereas Rootree ’ s semi-automated line used to yield six to ten ready-to-fill coffee bags per minute . The removal of the former bottleneck in the production process allows a unique combination of Rootree ’ s portfolio to shine . “ We are currently the only Canadian company offering in-line valve application combined with digital printing for flexible packaging ,” Pia Simran explains . Digital printing requires much less time-consuming preparation than other printing methods . “ This makes it both really fast and ideally suited to smaller batch sizes . In combination with our new , automated valve application solution , we can now offer our customers very competitive lead times .”
