Machine overview
Application and operating principle
The LU-420GSY addresses liquid and paste packs above the smallest single-dose format. A product tank and feed pump supply the dosing system while the VFFS section forms, fills and seals the pack from roll stock.
Well suited to
- Sauces and liquid food products
- Oils and pourable dressings
- Gels, creams and selected cosmetics
- Compatible household and industrial liquids

Common options and engineering decisions
- Agitated or heated product tank
- Pump and valve configuration matched to viscosity
- Clean-in-place or strip-cleaning review
- Conveying, coding and leak inspection
Performance validation
Confirm with product and film trials
Target output and dose repeatability are affected by product flow, environmental conditions, sachet length, film sealing window, changeover and quality-control settings. Supply representative product and production film for a meaningful test.
Any stated speed, range or accuracy is an indicative reference rather than a universal guarantee. Contract acceptance criteria should be documented for the final configuration.

LU-420GSY questions
What is the difference between this machine and the LUFS200D1?
The LU-420GSY is positioned for larger reference doses and wider packs, while the LUFS200D1 focuses on compact 5–100 ml sachets.
Can it handle hot-fill products?
Potentially, subject to product temperature, film, seals, tank and hose specification. Hot-fill duty must be declared during engineering review.
How do viscosity changes affect dosing?
Temperature and batch variation can change product flow. Agitation, heating, pump selection and recipe control may be needed to maintain repeatability.
Your next step. Send a representative product sample, target dose, sachet drawing, film specification and required output. Lancing Ltd will confirm the practical machine configuration, trial plan and acceptance criteria for your application. See related machine information.

Production specification for LU-420GSY
Develop the LU-420GSY around viscosity, product feed and larger sachet geometry
The published 100–1000 ml reference places this configuration in a larger liquid and paste pack range. Product pressure, temperature, particles, nozzle cut-off and the forming path must be balanced so the dose enters the pack cleanly and leaves an uncontaminated cross seal.
Project questions to answer before final specification
- What is the viscosity and flow behaviour at the actual filling temperature, including stringing, separation and suspended particles?
- How will the machine be supplied from the product tank or upstream vessel, and what level, pressure, agitation or heating control is required?
- Which doses, bag widths and lengths are commercially required, and what headspace is available above the product?
- What product-contact materials, seals, hoses and cleaning method are required for the formulation?
- How will dose, seal integrity, accepted output and normal pump-feed interruptions be verified?
Stable product feed is essential for a larger pump-fed dose
Viscous products can change with temperature, residence time and shear. A feed pump and tank that appear adequate in a short test can behave differently during a longer run or after a pause. The trial should therefore record product condition and should include normal start-stop and refill behaviour.
Larger doses also need enough time and headspace for product to settle below the cross seal. Nozzle placement, fill profile and bag support should prevent splash, smear or product pressure from distorting the pack while the jaws close.
| Product-feed test | Run the intended tank and transfer arrangement and record pressure, temperature and behaviour through normal stops and replenishment. |
|---|---|
| Dose matrix | Test the lowest, typical and highest commercial doses using the agreed measurement method. |
| Pack geometry | Run the critical width and length combinations and verify fill level, headspace, bag support, cut and presentation. |
| Seal integrity | Inspect for smear or trapped product and apply the agreed integrity or leak-test method after any required conditioning. |
| Accepted output | Count saleable bags under declared product-feed, coding and inspection conditions, including normal reject handling. |
When a smaller sachet or premade pouch route may be better
Small doses and flat sample packs can favour a compact piston VFFS machine. A zipper, spout, gusset or premium converted shape may justify a premade-pouch filler instead of a reel-fed bag.
Record the configuration that produced the result
A useful trial record identifies the product and film batches, dose setting, sachet dimensions, forming and sealing parts, coding setup, operating speed, stops, rejected packs and quality checks. Retained samples should be labelled so results can be traced to the lane, recipe or test condition where relevant.
The final quotation and acceptance schedule should distinguish indicative catalogue references from the values that will be demonstrated with the agreed product, pack and utilities.
Additional buyer questions
LU-420GSY project questions
Can the LU-420GSY handle products containing pieces?
It may be possible if the pump, valves, hoses and nozzle pass the largest pieces reliably. Provide particle dimensions and concentration and prove cut-off and seal cleanliness with the actual product.
Why is filling temperature important?
Temperature can change viscosity, pressure, dose behaviour, cut-off and film sealing. The intended operating range should be included in trials and the final specification.
Can the same setup run 100 ml and 1000 ml?
The reference range does not mean every product covers both extremes with one set of parts. Piston, pump, nozzle, bag format and cycle time must be checked for each commercial dose.
How should a paste-pack leak test be selected?
The pack owner should choose a method appropriate to the product, laminate, seal and distribution risk. The trial then records test conditions and retains traceable samples.
