Les ulis, france, october 12, 2015. Fifty years ago, the &ldquoformfillseal&ldquo concept developed by ima erca marked the dawn of a new era in the packaging machinery industry. It dramatically simplified the entire production process for packing liquid and pasty foods now a single machine could be used to form cups of different sizes from plastic film, fill them with yogurt, sour cream or similar products, and seal them immediately. Moreover, the ffs concept made it possible to achieve higher standards of hygiene than had been the case with preformed cups.
