'''Plastic Pouch Bag Making Machines''' are a sub-category of the [[Bag making machine| Plastic Bag Making Machines]] nevertheless they are discussed in a separate article, as the underlying technology of the two bag making types are different.  As the last unit of the converting line, bag machines process the printed and slitted plastic roll-film.

Plastic bag making machines produce bags that are either side sealed, or bottom sealed (sometimes referred to as bottom weld / bottom welded.) For both the bottom sealed bag and the side sealed bag, the main input material of the bag making process is two-layer roll-film.  For the bottom sealed bag machines the input film is tubular shaped. On the other hand, for the side sealed bag machines, the input film is a single-layer roll film that is folded up to two layers by a v-shaped banding frame at the front end of the bag machine.
