From roll stock to a finished zipper pouch
What is the HMK420 flexible packaging machine?
The HMK420 is a horizontal form-fill-seal machine that makes zipper stand-up pouches from roll film, opens each formed pouch, receives a measured product dose, seals and cools the top, then discharges the finished pack.
Select its forming modules, dosing equipment and connected accessories for the actual product and package. A line using supplied, already manufactured bags follows the separate premade pouch packing route.
Pouch formats & forming options
Make the package your product needs
The referenced project combines a bottom gusset, zipper, tear notches and a Euroslot. Selected modules and tooling determine the installed package features.
Reclosable retail package
Zipper stand-up pouch
Review the bottom gusset, zipper placement, seal widths and opening access together. The filled pack must stand and reclose as intended.
Selected retail features
Tear notch & Euroslot
Include easy-open and hanging-hole tooling in the pouch drawing and equipment list. Confirm their position relative to the zipper, artwork and top seal.
Schematic package illustrations. Final dimensions and feature positions follow the approved production drawing.
Review roll film, zipper, artwork and forming dimensions
- Width, height, gusset depth, zipper position and all seal widths
- Laminate structure, thickness, heat-seal layer and suitable sealing conditions
- Print repeat, registration mark, film width, reel diameter, core and unwind direction
- Zipper profile, supply condition, welding requirements and reclosure performance
- Tear notch, hanging hole, corner shape, coding area and change parts
Use the HFFS film specification guide and bottom-gusset forming guide with the actual pouch drawing.

Open the two gummy-cluster pack references
| Project pack | Dose target | Pouch face-size reference | Foreseen output |
|---|---|---|---|
| Small project pack | 85 g | 100 × 130 mm | 80 pouches/min target |
| Large project pack | 150 g | 200 × 200 mm | 80 pouches/min target |
Both packs have a 1.5% proposed dose-tolerance target. Final dose tolerance, pouch size and output require product samples, packaging films and testing. Approve the complete gusset drawing separately from these face-size references.
These are references from one HMK420 zipper-pouch proposal. It names HMK420-FED in the equipment list and HMK420-4 in the main-machine table; confirm the final suffix and configuration in the current signed proposal.
How the line works
From roll film to a sealed zipper doypack
Coordinate forming, pouch transfer, filling and sealing as one production process. Selected modules define the final station layout.
Unwind & align
Feed the approved film under controlled tension and alignment.
Form the gusset & seals
Create the specified bottom geometry and pouch seal structure.
Add zipper & retail features
Use the selected zipper welding, tear-notch, hanging-hole and coding modules.
Cut & transfer
Separate the formed pouch and carry it to the opening and filling positions.
Open & verify
Open the mouth and bottom; confirm the required pouch condition before filling.
Dose & settle
Release the measured product and keep the top-seal area clear.
Top seal & cool
Apply the approved sealing settings and stabilize the closed seam.
Discharge & transfer
Release the finished pouch to the selected outfeed or downstream equipment.
Machine details
See the mechanisms that handle your pack
Reference photographs show relevant pouch-transport, opening and sealing mechanisms. The approved equipment list defines the installed components.
Servo pouch transport
Review pouch position and controlled movement between the forming, opening, filling and sealing stages. Confirm lubrication points, maintenance and format adjustment for the supplied machine.
Pouch opening & detection
Review the selected vacuum opening, mechanical assistance and bottom-opening arrangement with actual film and zipper samples. Verify the response when a bag is missing or its opening is invalid.
Top sealing & cooling
Validate seal temperature, pressure, dwell and cooling with the approved laminate. Agree the inspection method for contamination, wrinkles and seal integrity.
Review product settling, hopper cutoff and seal-area protection
- Product drop height and transfer path for fragile or coated pieces
- Selected bottom-opening or shaking assistance for the package and product
- Hopper closure or dosing cutoff when required to control tailing
- Dust or splash control appropriate to the selected filling method
- Opening-detection response, rejects, cleaning access and safe restart
The pouch opening and filling guide connects these checks to the actual dosing handoff.
Complete packaging-line configuration
Select the machine, filler and accessories together
The gummy-cluster proposal pairs the HMK420 with a multihead weigher, product elevator, installation platform and outlet conveyor.
Pouch forming & sealing
HMK420 main machine
Forms and handles the roll-film zipper pouch. Its project output target is 80 bags/min, with the approved product and material.
Separate dosing component
14-head multihead weigher
1.6 L bucket reference; 30–1,000 g weighing range. The proposed gummy packs target 85 g and 150 g.
Selected connected equipment
Feed, platform & outfeed
Review product loading, access to the weigher, supporting platform and finished-pouch discharge with the full line layout.
Read the separate weigher and complete-line boundaries
The selected weigher lists a theoretical 120 ppm speed and theoretical 0.5–1.0 g accuracy; both vary with the product and target weight. These component values do not establish accepted HMK420 line output or finished-pack accuracy.
- Confirm the named weigher and hopper arrangement for your product
- Approve the full layout, working platform, elevator and cleaning access
- Include accessory power, air and other utility requirements
- Agree accumulation, inspection, reject and downstream handoff duties
- Resolve the proposed platform dimensions in the approved layout; the quotation and technical table differ
Product applications & filling options
Choose the filling system for your product
The gummy-cluster references are project-specific. Other products need their own dose, package, filling and sealing review.
