09 Mar 2017 --- In order to respond even more flexibly to customers’ wishes, SternMaid has invested in a Doypack line. From now on, the contract manufacturer and co-packing service provider will be able to pack end products in ready-made stand-up pouches with or without a zipper and three- or four-edge seal bags. Up to 40 bags per minute can be filled with dry beverage bases, superfoods, powdered dietetic drinks or products for athletes.
