| Still Water and Low-Viscosity Beverages |
Free-flowing liquids with low solids content and low resistance to flow.
Examples include drinking water, flavored water, and some non-carbonated beverages.
|
Flowmeter-based or timed volumetric filling. Gravity or low-pressure filling may be suitable when the product is stable and easy to drain.
|
2–5 L
10–20 L
Single-track
Multi-track
|
Accurate fill volume, hygienic product-contact parts, reliable spout sealing, and protection against leakage during handling.
|
Fast bag loading, automatic nozzle insertion, adjustable dosing, drip control, and simple clean-in-place capability.
|
Excessive foaming, unstable flow measurement, or poor nozzle shut-off can reduce filling accuracy and contaminate the seal area.
|
| Juices, Smoothies, and Pulpy Drinks |
May contain suspended pulp, fibers, or small particulates. Viscosity can vary with temperature and formulation.
|
Positive-displacement, mass-flow, or carefully controlled volumetric filling. Gentle product handling is preferred for products with delicate particles.
|
2–10 L
10–20 L
Wide-opening Spout
|
Particle passage must match the nozzle and valve design. The bag film and fitment should tolerate the selected thermal or aseptic process.
|
Large-bore product paths, low-shear pumps, temperature compensation, anti-drip valves, and easy disassembly for sanitation.
|
Narrow flow paths may block, shear-sensitive ingredients may be damaged, and pulp can interfere with sealing if the nozzle is not clean.
|
| Dairy and Dairy-Alternative Products |
Often sensitive to microbial contamination. Viscosity ranges from fluid milk-like products to thicker plant-based beverages.
|
Aseptic filling for shelf-stable products; hygienic cold filling for products distributed under refrigerated conditions.
|
1–5 L
10–20 L
Aseptic Fitment
|
Validated sterilization or sanitation procedures, compatible barrier film, hygienic connections, and controlled sealing conditions are essential.
|
Closed product circuit, sterile-air management where required, automated cleaning, monitored temperatures, and recipe control.
|
A hygienic filler does not automatically provide commercial sterility. Process validation, packaging compatibility, and downstream handling remain necessary.
|
| Wine and Other Still Alcoholic Beverages |
Low to medium viscosity liquids that may be sensitive to oxygen pickup, oxidation, or flavor loss.
|
Volumetric or mass-flow filling with low-turbulence operation. Inert-gas management may be used when oxygen control is important.
|
2–10 L
10–20 L
High-Barrier Film
|
Oxygen-barrier packaging, low-oxygen filling practices, compatible closures, and accurate headspace control where applicable.
|
Low-shear pumping, controlled product transfer, optional gas flushing, accurate metering, and cleanable stainless-steel contact parts.
|
Oxygen ingress can shorten product life. The complete package, including film, fitment, closure, and handling, must be evaluated together.
|
| Edible Oils and Liquid Ingredients |
Generally low in water activity, but viscosity varies significantly with temperature and oil type.
|
Mass-flow or positive-displacement filling is commonly considered for repeatable dosing, especially when viscosity changes.
|
2–20 L
Industrial Sizes
Chemical-Resistant Fitment
|
Oil-compatible film and fitment materials, secure seals, accurate gross or net weight control, and resistance to stress cracking.
|
Heated or temperature-conditioned product lines when needed, load-cell integration, robust valves, and flexible recipe settings.
|
Temperature-dependent viscosity can cause dosing variation. Residual oil on the seal surface may weaken or contaminate the closure.
|
| Sauces, Syrups, and Concentrates |
Medium to high viscosity products that may be shear-sensitive, sticky, or difficult to drain from the product circuit.
|
Positive-displacement pump filling, such as lobe, piston, or progressive-cavity arrangements, selected according to viscosity and shear sensitivity.
|
1–10 L
10–20 L
Large-Diameter Spout
|
Strong fitment welds, wide flow paths, controlled product temperature, clean cut-off, and film with sufficient puncture resistance.
|
Heated hopper or piping where required, slow-start control, anti-stringing nozzle design, high-torque drive, and tool-free sanitation access.
|
Product strings can foul the seal area. Pump selection that creates excessive shear may alter texture or cause air incorporation.
|
| Liquid Foods with Particles |
Products such as soups, stews, or fruit preparations may contain solid pieces whose size, shape, and concentration affect flow.
|
Low-shear positive-displacement or controlled gravity filling, subject to particle size, solids concentration, and required fill accuracy.
|
2–10 L
10–20 L
Large-Bore Fitment
|
The nozzle opening, valve geometry, film strength, and fitment must accommodate the largest particle without damaging the package.
|
Gentle pumping, enlarged product passages, agitation control, blockage detection, and quick-release parts for cleaning.
|
Particle settling can create inconsistent fills. Bridging, blockage, and trapped product may increase sanitation and maintenance demands.
|
| Non-Food Liquids |
Includes detergents, liquid fertilizers, cosmetic liquids, and other formulations with varying viscosity, foaming behavior, and chemical compatibility.
|
Volumetric, mass-flow, or positive-displacement filling selected after confirming chemical properties and required accuracy.
|
1–20 L
Industrial Sizes
Chemical-Resistant Film
|
Chemical compatibility, vapor control where necessary, secure closures, puncture resistance, and clear separation from food-use equipment.
|
Corrosion-resistant wetted parts, foam-control programming, grounded components where required, leak detection, and guarded operation.
|
Product compatibility must be checked for every wetted material. Flammable, corrosive, or hazardous products may require additional engineering controls.
|
| Aseptic Shelf-Stable Products |
Products intended to remain commercially sterile at ambient temperature for their validated shelf life.
|
Aseptic filling within a validated sterile zone, combined with a suitable product sterilization process and pre-sterilized or sterilizable packaging.
|
1–20 L
Barrier Film
Sterile Fitment
|
High-barrier multilayer film, sterile fitment design, validated sterilization, controlled environment, and documented critical limits.
|
Sterile-air or sterile-gas control, automated sterilant management, environmental monitoring, recipe locking, alarms, and audit records.
|
Aseptic performance depends on the complete system, not only the filler. Inadequate validation or weak package barriers can compromise shelf life.
|
| Refrigerated or Short-Shelf-Life Products |
Products whose safety or quality depends on cold-chain distribution and a defined use-by period.
|
Hygienic filling with controlled exposure time. Filling equipment should support validated cleaning and sanitation procedures.
|
1–20 L
Standard Fitment
Cold-Chain Package
|
Suitable barrier properties, reliable seals, cleanable product paths, and packaging dimensions compatible with chilled transport and storage.
|
Hygienic design, automated cleaning sequences, short product residence time, temperature monitoring, and production traceability.
|
The filler cannot compensate for poor refrigeration, excessive hold time, or inadequate sanitation. The distribution process must be included in validation.
|
| Multi-Format Production Lines |
Facilities filling multiple products, bag sizes, fitments, or production volumes on the same equipment.
|
A configurable system with changeable dosing recipes and product-contact components matched to each product family.
|
1–20 L
Multiple Bag Sizes
Change Parts
|
Consistent bag registration, repeatable fitment positioning, fast and validated changeovers, and clearly separated product-contact sets where needed.
|
Tool-less changeover, recipe management, servo-controlled dosing, automatic format adjustment, cleaning verification, and production data logging.
|
Maximum flexibility may reduce peak speed. Changeover time, operator training, spare parts, and sanitation between products should be costed.
