This type of vertical form, fill, and seal machine creates strip foil packages that may contain objects such as tablets. Pharma strip packager VFFS machines use two rolls of foil which are set opposite to each other. As foil is pulled from each side, it is fed through rollers. Capsules or tablets are fed into a hopper that distributes them into rows. The pills are dispensed between the foil layers as the foil passes through the rollers. Cavities in the rollers protect the capsules or tablets and allow the machine to laminate the foil. After filling and sealing the cavities, some machines perforate and cut the packets, while others cut the packets apart without perforating.
