[Filling lines]

Liquid Filling Lines Built Around Your Product

Define the liquid and the container first; the filling, capping and labeling stations follow from that.

[01]

Product and Container Requirements

Liquids differ more than they look. The same bottle can be easy with one liquid and awkward with another, so start with the product.

What you know about the liquidWhat it changes on the line
Thin and free-flowing (water-like, light oils)Drip after shut-off is the main worry, so drip trays, nozzle shut-off and bottle spacing matter.
Slightly thicker (many oils, liquid soaps)Fill time per container grows with viscosity, and the filler must keep up without splashing.
Foams when poured (shampoo, detergents)Nozzle approach and fill rate are set to keep foam out of the neck. See the shampoo page.
Thick or with piecesMoves toward paste territory. See the paste filling lines page.
Hazardous or aggressive (strong acids, solvents, flammables)We assess these separately. This page makes no claim that we can handle them.
ContainerNeck opening, height, stability and closure style decide handling, capping and labeling. Drawings or photos with dimensions help.

Select the Filling Technology

General engineering notes on the common filler types.

Filler approachCommonly considered forWatch points
Volumetric pistonLiquids from thin to viscous where each container should get a set volume.Seals and cleaning; the piston, valve and nozzle all touch the product.
Pump-driven dosing (for example peristaltic)Products where a short, simple product path helps cleaning.Tubing wear; pulsation at the nozzle on some designs.
Level-based or overflow fillingClear liquids in clear bottles where the same fill height looks neat.Depends on a stable bottle neck and consistent container volume.
Gravity-fed fillingFree-flowing liquids at low output.Sensitive to product level in the tank and to foaming.

Match Capping, Labeling and Inspection

Capping depends on the closure. A capping head places and tightens screw caps. Flip-top and pump closures need orienting first. Trigger sprayers and pumps with dip tubes are slower to handle, so we look at them case by case.

Labeling follows container shape. Our catalog has wrap-around labelers for round containers, flat-surface labelers for square bottles and flat or oval personal care bottles, and shrink-sleeve lines for full-body coverage. The examples below link to the product pages for specific liquids.

Coding and inspection are options, such as a missing-cap or missing-label check, or a code printed after labeling.

Liquid Line Examples from LINEVO PACK

Two of our product pages relate to liquid lines.

Flat-surface labeling machine with label reel and conveyor, olive-oil bottles in front

Edible oil bottling line

Labeling stage (flat surface)

Our line page lists liquid filling, capping and multi-side labeling for oil bottles. We go into filler details once we know the oil.

Output, Footprint and Utilities

We don't publish speeds or floor areas. They depend on the product, the container and the stations you choose, and the proposal states them.

  • Output per shift and how many shifts you run.
  • Fill volume per container, and how many formats share the line.
  • Room dimensions, door and ceiling clearances, and where the line enters and leaves (see line layout).
  • Power, compressed air and drain locations.
  • Whether the line must join a packing area or an existing conveyor.
  • Space for operators, maintenance access and staging containers and closures.

[06]

Cleaning and Changeover Requirements

Anything that touches the liquid has to be cleaned or flushed between products, so more wetted parts mean a longer changeover. Tell us how often you switch products and whether the next one differs in color, fragrance or allergen.

A new bottle changes more than the filler: neck size, height and shape affect nozzle position, capping heads, guide rails and labeling parts, and a new container or label can need new guides or holding parts. If you'll run several sizes, say so at the start and we'll plan for format change.

[08]

Scope of Supply and Quotation

A proposal says what is included, what is optional, what you provide and what sits outside the line. The table is the usual starting point for a liquid line, and every line is configured to your liquid and container and built to order.

  • Filling, capping and labeling stations

    As configured for the liquid and container.

    [Included]
  • Container feeding or unscrambling

    [Optional]
  • Coding and inspection

    [Optional]
  • Wetted materials and seals for your liquid

    Confirmed against the product information you send.

    [To be assessed]
  • Case packing and palletizing

    [To be assessed]
  • Bulk storage, blending and product preparation

    [Excluded]
  • Power, compressed air, drains and floor

Common Questions

01How is a liquid filling line different from a single filling machine?
A line adds the stations around the filler: capping, labeling and the conveyors between them. Most of the design work is getting them to run at one pace.
02Which filler is right for my liquid?
That depends on viscosity, foaming, particles and the container opening. Send us the product details on WhatsApp and the proposal will name the filler type.
03Can you fill corrosive or flammable liquids?
We assess those separately, and nothing on this page assumes we can. Describe the liquid and send the material safety information you have, and we'll tell you whether we can consider it.
04Can one line run several bottle sizes?
Yes, if it's planned that way. A size change affects the nozzle, capping head, guides and labeling parts, so list every size up front.
05Are the output figures on this page?
No. Output depends on the product, the container and the stations chosen, and the proposal states it.
