1. A method for making a multi-compartment package, said method comprising the steps of:
forming a folded packaging film web from an unwinding roll of packaging film; forming a first vertical end seal on said folded packaging film web; forming a vertical middle seal on said folded packaging film web; forming a second vertical end seal on said folded packaging film web, wherein said vertical middle seal is located between said first vertical end seal and said second vertical end seal; cutting said folded packaging film web at said first vertical end seal and said second vertical end seal to produce a multi-compartment, vertically oriented pouch having a top, as well as a first compartment and a second compartment separated by said vertical middle seal, wherein each said compartment comprises an open mouth at the top of the pouch; optionally opening said open mouths; filling each said compartment through its open mouth with a predetermined amount of a first product or a second product; forming a horizontal top seal on said pouch which closes said open mouths and forms a sealed first compartment between said first vertical end seal and said vertical middle seal, and a second sealed compartment between said second vertical end seal and said vertical middle seal.
