Standard doypack
A simple reference contour with the widest process tolerance.
Shaped pouch engineering
Shaped Doypack Packaging Solutions
Engineer bottle-shaped and contour-cut pouches from the controlled pack drawing outward—geometry, film path, die-cut tooling, opening access, filling behaviour and FAT evidence must work as one HFFS process.
Every shoulder, neck and contour changes the usable process window.
What is a shaped doypack packaging solution?
A shaped doypack packaging solution forms, cuts, opens, fills and seals a bottle-shaped or contour pouch from roll film. The equipment route cannot be selected from speed alone: pouch geometry, laminate response, registration, tooling clearance, filling-head access and accepted-output criteria must be validated together. This page owns the pouch-format and application decision; model-specific specifications remain on the corresponding product page.
Geometry before machinery
Each contour changes the process window
More complex geometry reduces tolerance for web drift, registration error, die-cut variation, narrow seal zones and restricted filling access.
Contour-cut doypack
Shoulders and side contours introduce additional tooling and registration boundaries.
Bottle-shaped pouch
Neck, shoulders and a bottom gusset must leave enough opening and sealing access.
One controlled sequence
From roll film to accepted shaped pouch
The exact station arrangement is project-specific, but every viable route must control the same eight engineering stages.
Unwind and register
Control tension, tracking and print position before forming.
Build the gusset and seals
Establish the pouch body before contour cutting.
Create the contour
Protect seal width and drawing tolerances at the tooling stage.
Separate and open
Confirm access with the real laminate and pouch memory.
Coordinate filling travel
Keep the nozzle clear of the contour and seal zone.
Top seal and cool
Validate time, temperature, pressure and contamination control.
Inspect accepted output
Judge the finished pouch against agreed evidence.
Record the approved state
Lock drawings, settings, samples and restart criteria.
Engineering controls
Controls that matter on an irregular contour
Final components follow the approved project BOM. The selection logic below is more important than an unsupported universal component list.
Web tracking
Registration evidence must cover normal running, restart and roll change.
Contour tooling
Die-cut clearance must protect the minimum usable seal width.
Opening assistance
Vacuum, mechanical or air assistance is selected from the pouch behaviour.
Filling travel
Nozzle position and settling time must keep the final seal area clean.
Seal control
Seal settings are validated against the actual laminate and contamination risk.
Inspection evidence
Accepted output is defined by the project test method, not appearance alone.
Route selection
Choose the configuration after the pouch is defined
Internal source documents describe both a high-output four-working-station reference and a duplex shaped-pouch reference. They are different project routes, not interchangeable universal specifications.
| Decision factor | Four-working-station reference | Duplex reference |
|---|---|---|
| Best starting point | Projects with a validated bottle-shaped pouch drawing and a higher accepted-output requirement. | Projects that need a two-station shaped-pouch route evaluated around a controlled sample. |
| Source application | 120 g tomato paste or puree in a bottle-shaped doypack. | 20 ml liquid gel in a shaped doypack. |
| Source output | 160–200 bags/min in the referenced configuration; not a promise for every product or pouch. | 80 bags/min in the referenced application; final output remains subject to sample trials. |
| Source pouch reference | 80 × 120 × 20 to 105 × 210 × 35 mm for the documented four-working-station configuration. | A 53 × 112 mm application example is documented; the final range follows the approved drawing. |
| Approval gate | Use the signed proposal, controlled drawing, named model, production sample, URS and FAT criteria. The HMK420Q/HMK4200 naming conflict must not be treated as a confirmed synonym. | |
Reference values are conditional examples from internal source documents, not a universal shaped doypack machine specification.
FAT evidence
Approve evidence, not an isolated speed number
A useful acceptance plan records the complete shaped-pouch process and the conditions under which the result was achieved.
Revision, dimensions, seal zones, gusset and contour tolerance.
Laminate, thickness, print repeat, roll condition and splice route.
Opening success and filling access through normal running and restart.
Defined inspection or test method using agreed reference samples.
Run time, counted input, accepted packs, rejects and recorded stoppages.
Approved parts, recipes, checks and restart acceptance criteria.
My Insight
A distinctive contour is not a cosmetic machine option
The pouch outline changes the forming, cutting, opening, filling and sealing process at the same time. Approving a machine before the controlled drawing and sample trial are stable transfers too much risk into commissioning. Freeze the pouch geometry first, then compare equipment routes against the same accepted-output evidence.
