HMK420Q High-Speed Doypack Packing Machine
The HMK420Q is a full-servo, four-station horizontal form-fill-seal system for roll-stock doypacks. A quoted reference configuration targets 160–200 bags/min; accepted output must be verified with the agreed product, dose, pouch, film and FAT method.

What is a high speed doypack packing machine?
A high-speed doypack packing machine is an HFFS system that forms pouches from roll film, meters the product and seals the finished pack in one controlled sequence. The HMK420Q reference configuration uses four working stations and has a quoted speed range of 160–200 bags/min for the agreed application. Actual accepted output depends on product behaviour, dose, pouch geometry, film and downstream conditions.
HMK420Q full-servo quadruplex HFFS platform
INMAYPACK developed the HMK420Q as a four-station member of its roll-stock doypack machine range. Servo electronic-cam control coordinates forming, transport, filling and sealing. Recipe changes can adjust controlled values at the HMI, while tooling, filler parts, cleaning and first-off approval remain part of a real format change.
The source proposal covers a bottle-shaped doypack application for tomato paste or purée. Other pouch contours, closures and products require a controlled drawing, confirmed filling system, film trial and project-specific acceptance plan.
Engineering features that support high accepted output
These subsystems must be validated as one process. Rated speed alone does not prove filling accuracy, seal integrity or saleable output.
Servo linear-motor transport
Coordinated transport reduces dependence on conventional cam-splitter and screw-drive architectures. Positioning repeatability is verified during the agreed production trial.
Four working filling stations
The quoted sauce configuration uses four servo micro-rotor pump fillers and a 100 L jacketed tank. Different products require a separately confirmed dosing arrangement.
Verified pouch opening
Vacuum and mechanical opening are monitored before filling. The interlock is intended to reduce avoidable product loss and seal-area contamination.
Multi-position sealing process
Sealing and cooling stations must be qualified with the intended laminate, sealant, contamination condition and accepted test method.
Web guiding and registration control
Film pulling, break detection and correction support print-registration control within the validated roll, artwork, setup and speed window.
Electronic-cam recipe control
The HMI manages controlled motion and format parameters. Optional zipper, spout or punching stations are included only when stated in the approved project scope.

Which applications belong on the HMK420Q platform?
Use product behaviour, dose, pouch geometry, filling time and seal-area cleanliness to qualify the application before selecting the final configuration.
Confirmed reference application
Tomato paste or purée in a bottle-shaped doypack, with a reference dose of 120 g or less.
Viscous sauces and condiments
Confirm viscosity, particulates, temperature, nozzle motion, settling time and clean-seal requirements with samples.
Other pumpable liquids
Filler type, tank design, cleaning method and splash control must be specified for the actual product.
Powders and granules
A different dosing system and dust or product-settling study are required; the quoted sauce configuration does not prove these applications.
Standard stand-up pouches
Confirm roll-film drawing, gusset geometry, filling access, seal width and accepted finished-pouch tests.
Shaped or bottle-shaped pouches
Review the controlled contour, die-cut tooling, web tracking and opening access before approving the layout.
Zipper or spout formats
Treat each closure as a project option requiring dedicated tooling, process time and FAT evidence.
Unsupported applications
Do not assume compatibility from a product name alone. Approve the route only after sample testing and a written configuration review.
Engineering Details, Up Close
HMK420Q high-speed doypack machine FAQ
What output can the HMK420Q achieve?
The source proposal gives a reference speed of 160–200 bags/min for a four-station configuration. Contract acceptance should use agreed product, dose, pouch, film, test duration, reject limits and downstream conditions.
Which application is confirmed by the source proposal?
The confirmed reference application is tomato paste or purée in a bottle-shaped doypack or flat bag, with a reference dose of 120 g or less. Other products and formats require a separate engineering review.
Can the HMK420Q run shaped, zipper or spout pouches?
The platform may be configured for additional pouch features, but each contour or closure changes tooling and process scope. Compatibility is confirmed only after the controlled pouch drawing, film, filling access and FAT evidence are approved.
How long does a format change take?
The HMI can change controlled recipe values, but the complete changeover may still include pouch tooling, filler parts, product cleaning, film setup and first-off release. Confirm changeover time against the approved format matrix during FAT.
What determines the HMK420Q project price?
Pricing is configuration-based. The commercial boundary changes with the filler, tank, pouch tooling, closures, coding, inspection, conveyors, utilities, documentation, commissioning and spare-parts scope.
How should warranty and support be evaluated?
Use the signed quotation and contract to confirm warranty period, exclusions, spare-parts response, remote support, installation, training and travel costs. Do not use a generic website statement as the acceptance document.
How should HFFS and premade pouch systems be compared?
Compare roll-stock and premade-pouch routes with your annual volume, material prices, tooling, waste, labour, changeover, cleaning and accepted output. A universal percentage saving or payback threshold is not reliable without project data.
High-Speed Doypack Engineering Library
Specify accepted output—not only rated machine speed
A 160–200 bag/min machine must be evaluated as a complete pouch-production system. Lane architecture, film, filling time, opening reliability, seal quality, changeover scope and FAT criteria determine whether rated speed becomes stable saleable output.
Start with the lane-capacity decision
Compare single-station and four-station architectures by accepted output, balance, cleaning, maintenance access and lifecycle capacity before fixing the machine layout in the URS.

HFFS or premade pouch?
Compare roll-stock forming with premade pouch handling by format freedom, changeover, material supply and production economics.
Review the HFFS vs premade pouch decisionFilling
Match the dosing system to the product
Use product behavior, dose range, accuracy, cleanability and required fill time to select the filler that will support the target cycle.
Choose a pouch filling systemPackaging Material
Define a machine-ready film specification
Record roll, web, laminate, registration, sealant and splice requirements so the material can be qualified for the intended speed window.
Build the HFFS film specificationProcess Stability
Control pouch opening and filling
Separate opening, detection, nozzle motion and product behavior when unstable filling limits accepted output or contaminates the seal area.
Review pouch opening and fillingQuality
Validate the sealing process window
Connect film structure, temperature, dwell, pressure, contamination control and test methods instead of judging seals by appearance alone.
Review stand-up pouch seal integrityAcceptance
Write evidence-based FAT criteria
Define the product, pouch, duration, accepted output, rejects, alarms, changeover and document deliverables before the factory test begins.
Use the stand-up pouch machine FAT checklistOperations
Protect output during format change
Control parts, recipes, cleaning, first-off checks and production release so short changeovers do not create extended startup losses.
Plan pouch machine changeoverLifecycle
Plan maintenance and recovery
Connect preventive tasks, failure evidence and machine-specific spare parts to the availability required from a high-output line.
Build the preventive maintenance planProcurement checkpoint: ask for one agreed production basis—product, dose, pouch, film, lane count, test duration, acceptable rejects and downstream condition. A speed value without these boundaries is not an acceptance criterion.
