Pouch and vacuum bag making
Pouch machines produce vacuum bags from reels of a film or laminate. These machines may have different constructions depending on the type of pouch they produce. A common application is Doypack, or stand up pouch. It is a sachet with a bottom fold and a particular outlay of stiffening welds which creates a modern and universal packaging that can stand up on its own. Other common applications are 3 side weld bags and stand up pouches with square bottoms.
