A pouch for use in packaging food or similar granular materials is disclosed which includes at least two different and segregated pouch compartments combined in a single unit. The two pouches may be each formed of different sheet materials so that a differential level of protection may be provided for the different materials in each of the two pouches. The two pouches are simultaneously formed in a folding and sealing machine with the top edges of the two pouches being sealed together to form a single dual compartment package.
