Abstract

An improved package forming and filling apparatus is described which has three chambers 1,2,3 in series. Packaging foil is fed through the first, where it is exposed to some sterilising radiation, then through the second where it is exposed to ozone generated by corona discharge between electrodes 20 which the foil passes between, and then fed into the third chamber 3 where it is formed into a tube and the tube filled with fluent material and then separated into individual sealed sachets. The third section may be subjected to vigorous sterilisation before a filling operation by passing high ozone concentration air into it. Cooled air may flow in the direction of movement of the foil through the area of the corona discharge and accompany the foil into the third chamber 3 while maintaining the sterilising effects of the ozone generated by the corona discharge. A sterilisation apparatus is disclosed independently as well.
