3 and 4-Sided Pouches

Pouches, sometimes called sachets, are generally formed from roll fed filmstock. They can also be formed offline at a converter or elsewhere then filled and closed on a separate machine. When preformed pouches are used, the filling and sealing process is similar except that the pouches will be fed from a magazine rather than a roll.

Films can be any sealable material such as plastic, aluminum, paper or combinations. Generally, film requirements will be similar to those of VFFS and HFFS machines discussed in a previous white paper. This paper will focus on machinery that forms, fills and seals the pouches on a single machine.
