Doypack machine guide: stand-up pouch filling and sealing

What a doypack is, how doypack and stand-up pouch filling machines open, fill and seal zipper pouches, and which dosing unit suits powders, snacks and liquids.

Short answer: A doypack is a stand-up pouch with a gusseted bottom, often with a zipper or spout. Doypacks are made by converters and filled on a premade pouch machine, which picks each pouch, opens the zipper and mouth, fills it — by auger for powders, weigher for snacks, pump for liquids — and heat-seals the top.

Can a VFFS machine make doypacks?

Some VFFS machines make block-bottom or gusset bags, but true stand-up zipper doypacks are normally made by converters and run on premade pouch machines. See VFFS or premade pouch.

Zipper and seal quality

The opening station must open the zipper without tearing it, and the sealing jaws must seal above the zipper on thick laminates. Send sample pouches so jaws and grippers can be checked.
