Doypack Packing Machine — Stand-Up Pouch Form Fill Seal Solutions
INMAYPACK designs and manufactures horizontal form-fill-seal (HFFS) doypack packing machines that form, fill and seal stand-up pouches directly from roll film — for powders, granules, liquids and pastes. Eight machine families, one factory in Shanghai, exported to international markets since 2009.
Doypack Packing Machine: Definition & Key Facts
A doypack packing machine is a horizontal form-fill-seal (HFFS) system that automatically forms stand-up pouches (doypacks) from roll film, fills them with powder, granule, liquid or paste products, and heat-seals them — completing bag making, filling and sealing in one continuous line. Unlike premade pouch machines, an HFFS doypack machine forms the pouch in-line, cutting bag cost by roughly 30–50% at scale.
INMAYPACK is a doypack packing machine manufacturer founded in 2009 in Jinshan District, Shanghai. Its HS, HMK and HMS series cover standard, zipper, top-spout, corner-spout, liquid and shaped doypacks at speeds from 30 to 200+ pouches per minute, and are installed in food, beverage, pet food, chemical and personal-care plants across international markets.

How a Doypack Packing Machine Works: 6 Steps
An HFFS doypack machine converts flat roll film into filled, sealed stand-up pouches in one continuous process — no premade bags required.
Film Unwinding & Tension Control
Roll film is unwound with servo tension control and photoelectric edge tracking to keep print registration accurate.
Pouch Forming
A forming plow folds the film and creates the bottom gusset; optional stations apply zippers, spouts or Euroslot punching in-line.
Side Sealing & Cutting
Heated sealing jaws weld the side seams, cooling bars set the seal flat, and the web is cut into individual open-top pouches.
Pouch Opening
Oil-free vacuum suction cups and air blow open each pouch; opening detection blocks filling if a pouch fails to open — no product waste.
Filling
Auger fillers for powder, multihead weighers for granules, servo piston or rotor pumps for liquids and pastes — matched to your product.
Top Sealing, Cooling & Discharge
The top seal is welded, cooled and shaped; finished doypacks discharge on a conveyor ready for coding, cartoning or case packing.

Doypack Packing Machine — Frequently Asked Questions
A doypack packing machine is a horizontal form-fill-seal (HFFS) system that forms stand-up pouches from roll film, fills them with powder, granule, liquid or paste products, and heat-seals them in one continuous line. Because the pouch is formed in-line instead of purchased premade, film-based doypack production typically cuts per-bag material cost by 30–50% at scale.
INMAYPACK doypack machines pack powders (coffee, flour, spices), granules (candy, nuts, pet food), liquids (juice, detergent) and pastes (mayonnaise, ketchup, honey, face cream). The filling system is matched to the product: auger fillers for powder, multihead weighers for granules, and servo piston or rotor pumps for liquids and high-viscosity pastes.
Speeds range from about 30 pouches per minute on simplex horizontal machines to 160–200+ pouches per minute on duplex and quadruplex high-speed lines such as the HMK420 series. Actual output depends on pouch size, film structure, product flow characteristics and the filling system selected.
An HFFS doypack machine forms the pouch from roll film and then fills and seals it, giving the lowest per-bag material cost and full control of pouch features like zippers and spouts. A premade pouch machine fills and seals pouches that were manufactured in advance, which suits smaller batches, complex printed bags and quick product changeovers. INMAYPACK manufactures both types.
Yes. After your order and deposit are confirmed, INMAYPACK runs filling and sealing tests using your actual product and packaging film during machine build-out, then provides test videos and a factory acceptance report before shipment. Customers are also welcome to attend the factory acceptance test in Shanghai in person or via live video.
Every doypack packing machine includes a one-year warranty covering manufacturing defects, with free replacement parts shipped by international express within the warranty period. INMAYPACK provides technical support under the agreed service scope, remote diagnostics, English documentation, installation guidance and optional on-site engineer commissioning.
