Doypack filling machines for premade pouches.
Doypack filling needs the machine to hold the pouch stable through opening, filling and sealing so the finished pack remains neat and saleable.
What this page helps specify.
Use this page to prepare an accurate machinery enquiry before choosing a pouch filling machine route.
- Pouch width, height and gusset
- Zipper, spout, tear notch or valve
- Fill weight, dosing accuracy and product flow
- Seal area cleanliness and final pack handling

Recommended route to compare.
The correct system is normally selected from product behaviour, pack format and output target.
VFFS
Vertical form fill seal route
Best where film is formed into the pouch inside the machine for repeatable high-volume production.

Liquid & paste
Pump-fed filling route
Best where viscosity, foaming, dripping and seal contamination need to be controlled.

Quick answers.
What information should I send for a faster quote?
Send product samples or product notes, fill weight or volume, pouch drawings, required speed, utilities, container sizes and any coding, checkweighing or conveyor requirements.
Should I choose premade pouch filling or VFFS?
Premade pouches are suited to strong shelf presentation and formed packs. VFFS is usually considered when roll film, higher volumes or in-machine bag forming are required.

Doypack features that affect machine handling.
Doypack is a formed stand-up pouch format, but individual designs vary in stiffness, bottom-gusset geometry, opening, zipper, spout, seal area and how the pouch balances before and after filling. These details must be reviewed from actual samples.
Bottom gusset and stability
The gusset creates the standing base but also changes how the empty pouch sits in a magazine and how the filled pouch is supported. Provide flat and opened dimensions and a filled reference pack where available.
Zipper and opening
The zipper can reduce the clear mouth and stiffen the top of the pouch. The opening method and filling nozzle must clear the zipper while keeping product away from the final seal.
Spout and orientation
A spout changes balance and may require orientation, support and a dedicated filling connection. The location, neck, cap and fill method should be supplied in the drawing.
Top seal and presentation
Agree the available seal area, laminate, jaw contact, headspace, cooling and finished-pouch appearance. A pouch that stands correctly when empty may distort once filled.
Doypack trial specification.
Trial production-equivalent pouches with the normal manufacturing tolerance and intended product.
| Item | Evidence required | Acceptance focus |
|---|---|---|
| Pouch | Drawing, empty samples, opened sample and filled reference. | Magazine feed, pick-up, gripper area, opening and support. |
| Features | Zipper, spout, tear notch, gusset and code zone positions. | Clear fill path, orientation and no damage to features. |
| Laminate | Full construction and sealant layer. | Jaw settings, clean seal, cooling and integrity result. |
| Product | Representative sample, dose and normal variation. | Filler suitability, cut-off, settling and clean seal area. |
| Finished pack | Target headspace, appearance, code and quality method. | Standability, seal, leakage, code and repeatability. |
Doypack buyer questions.
Are all Doypack pouches handled in the same way?
No. Size, laminate stiffness, gusset, zipper, spout, opening and fill weight change how the pouch feeds, opens, grips and seals. Actual samples are needed for review.
Can a Doypack filler handle both zipper and plain pouches?
Possibly, but the opening, nozzle clearance, gripper positions and top-seal arrangement must be checked for both formats. Change parts or separate settings may be required.
How is a spouted Doypack filled?
The method depends on the spout, cap, orientation, product and required closure process. Provide the complete pouch and closure assembly so the filling connection and support can be specified.
What affects whether the filled pouch stands correctly?
Gusset formation, product distribution, fill level, trapped air, pouch support and the finished seal can all affect standability. Compare approved filled samples during the trial.
What should be checked at changeover?
Check magazine and guides, grippers, opening, filler/nozzle, seal-jaw position, code, recipe, first-off fill, seal integrity and the final standing appearance.
Send the real Doypack, product and filled reference.
Lancing can review the gusset, opening, zipper or spout, dosing, top seal and finished-pack acceptance as one cycle.
Create a Doypack format matrix before the machine is configured.
“Stand-up pouch” is not a complete machine specification. The same nominal size can behave differently because of gusset construction, laminate stiffness, zipper position, spout geometry, top trim and manufacturing tolerance.
| Format field | What to record | Why it matters |
|---|---|---|
| Overall dimensions | Flat width and height, bottom/side gusset and filled profile. | Magazine, gripper travel, station clearances and discharge. |
| Usable mouth | Opening below top trim, zipper or internal feature. | Opening device, chute/nozzle access and product clearance. |
| Zipper | Height, width, end condition and opening force on production samples. | Pickup stack thickness, opening reliability and clean top seal. |
| Spout | Position, angle, cap state, neck diameter and pouch support point. | Presentation, gripping, filling access and torque/closure integration if required. |
| Laminate | Supplier construction, sealant layer, thickness and surface finish. | Separation, friction, stiffness, jaw process and finished seal. |
| Tolerance | Supplier limits and measurements across more than one batch. | Adjustment range and robustness of the handling window. |
Use the opening and gripper guide to plan the handling test and the pouch material guide to collect the laminate evidence. Agree finished-pouch checks with the seal and leak-testing guide.
Send a pouch matrix, not one sample.
Include each intended format, product, dose and feature so the proposal can identify common settings, change parts and trial priorities.
Approve the filled Doypack shape as well as the empty pouch handling.
A stand-up pouch can feed and open correctly yet still fail the project brief after filling. Dose volume, product settlement, gusset opening, zipper or spout clearance and the top-seal band determine whether the finished pack stands, closes and presents as intended.
| Doypack feature | Machine interaction | Finished-pack check |
|---|---|---|
| Bottom gusset | Must open without losing the pouch datum or grip. | Base forms consistently and the filled pouch stands as required. |
| Zipper | Reduces usable mouth depth and changes opening force. | Zipper remains clean, undamaged and usable after filling and sealing. |
| Spout | Changes balance, pickup datum and nozzle access. | Spout and cap area remain undamaged and the pouch is stable. |
| Shaped sides or notch | Can affect magazine separation and gripper contact. | Shape remains aligned without marks in critical presentation areas. |
| High dose or low-density product | May need more settlement room and a longer fill sequence. | Product remains below the seal band and the pack has the agreed profile. |
Use the pouch fill-zone guide and record repeat setups with the changeover validation guide.
Revalidate a Doypack when the material construction changes.
A new mono-material, coating, zipper or spout can alter pouch separation, mouth opening, local thickness and top-seal behaviour. Test the final production construction and retain the approved machine and seal evidence.
Premade Doypack handling
Check magazine separation, gripper datum, zipper or spout clearance, usable opening and support during filling across normal pouch tolerance.
Seal and finished-pack acceptance
Agree the clean seal zone, jaw process, cooling, code position and the strength or integrity method used to release the pouch.
