To begin with, the types of spout pouches significantly influence the choice of filling machine. Whether it is a spout pouch with a single or double spout gap, the method of filling will vary accordingly. For instance, for all kinds of spout pouches that require filling from the spout, a suitable option would be the spout pouch filling and capping machine. On the other hand, corner spout doy packs, which necessitate filling from the top of the pouch and lack a spout gap, are better suited for a premade pouch filling and sealing machine.

Understanding the precondition of spout bag filling is equally crucial. This includes considering the specific requirements of the packaging content, such as viscosity, particulate size, and temperature sensitivity. The compatibility of the filling machine with these requirements is essential for achieving optimal results.
