Single-serve liquids and semi-liquids in narrow packs.
The format is useful for products requiring controlled portions and high printed-pack output.
Multi-lane liquid packaging
Liquid stick-pack machine.
A pump-fed format for portioned sauces, honey, edible oils, gels and beverages—configured around viscosity, inclusions, temperature and cleaning method.

01 / Application fit
The liquid determines the pump.
Viscosity alone is not enough. Product particles, foaming, stringing, temperature sensitivity and sanitation requirements all influence the filling circuit.
Viscosity, particles and cleaning.
Large inclusions, rapid settling, foaming or aggressive sanitation can change the pump, valve, hose, hopper and CIP scope. Provide the actual recipe and operating temperature.
02 / Operating principle
Meter the liquid without contaminating the seal.
The filling path must deposit a repeatable dose while keeping the film’s sealing area clean.
Condition the product
The hopper and liquid circuit maintain the required feed, temperature or agitation.
Select the pump action
Piston, ceramic or peristaltic pumping is screened against viscosity and hygiene.
Deposit each dose
The film is formed into lanes and the product is delivered with controlled timing.
Close the liquid pack
Heat and pressure make the final seals before straight, zigzag or round cutting.
03 / Key capabilities
Filling and sanitation are one system.
The selection should consider product recovery, changeover, cleanability and seal integrity—not only nominal output.
Multiple pump routes
Reference choices include piston, ceramic and peristaltic pumps.
Multi-lane filling
Parallel lanes increase output for suitable low-dose products.
Controlled film path
Servo pulling and registration controls support repeatable printed packs.
Seal temperature control
Independent control supports consistent sealing across the machine width.
Hygienic project options
Food-contact materials, circuit access and optional cleaning provisions are project-defined.
Secondary automation
Counting, collating, cartoning and case packing can extend the line.
04 / Reference specification
Engineering data.
The stated values screen the machine family; they do not replace a pump trial with the real liquid.
* Supplier reference data. Speed and accuracy depend on viscosity, temperature, particles, dose, pack size, pump and number of lanes.

Define the whole liquid circuit.
The pump is only one component between product preparation and a clean finished pack.

06 / Selection brief
A recipe sheet is more useful than “liquid”.
Give the engineering team enough information to screen the pump, seals and sanitation plan.
Start my configuration ↗- Liquid behaviour
Viscosity at filling temperature, particles, foaming, stringing and settling.
- Dose and tolerance
Nominal volume or weight, density and allowable deviation.
- Product safety
pH, temperature, allergens and food-contact material requirements.
- Cleaning method
Frequency, detergent, water temperature, CIP expectation and changeover time.
- Pack and output
Film structure, bag drawing, target cycles, lane output and secondary packing.
