Key Takeaways
A packaging line needs equipment for five jobs: feeding and dosing the product, forming or filling the pack, sealing it, coding or labelling it, and grouping it for dispatch. On a bagging line, one vertical form-fill-seal (VFFS) machine with a doser covers the first three jobs; on a bottle line, a filler, capper and labeller do them in sequence. A line is complete when every stage is either automated or has a clear manual step between machines. To see the machines that cover each stage, browse the packing machine catalogue.
Filling, forming, wrapping, labelling and end-of-line machines we supply, side by side.
Packaging machinery is the machines that do the packaging work: a VFFS bagger, a flow wrapper, a bottle filler or a shrink wrapper. Packaging equipment is the wider term. It includes that machinery plus everything that joins it into a line, such as conveyors, dosing units, check weighers, coders and the controls that keep the machines in step. Buyers often use the two words for the same thing, but the difference matters when you plan a packaging line, because the joining equipment is usually what decides whether separate machines work as one system.
Every packaging line moves through the same five stages, whatever the product. The machines change with the pack format, but the order of the stages does not.
| Stage | What happens | Typical machines |
|---|---|---|
| Feeding and dosing | The product is conveyed to the machine and measured by count, weight or volume | Auger fillers, cup dosers, multihead weighers, liquid pumps |
| Forming or filling | The pack is formed from film, or a pre-made container is filled | VFFS, HFFS, bottle, cup and tube fillers |
| Sealing and closing | The pack is sealed, capped or seamed shut | Sealing jaws, cappers, can seamers |
| Coding and labelling | Batch, date and product information is applied | Coders, labelling and shrink sleeve machines |
| End of line | Packs are grouped, wrapped or boxed for dispatch | Shrink wrappers, cartoners, case sealing |
One packaging machine often covers several stages of a line. The cards below show where the main machine types in the SA Packaging Machinery range sit on a packaging line; each links to the machine page with its configurations.
A vertical form-fill-seal (VFFS) machine forms bags from a roll of film, fills them from a doser above and seals them, so it covers the forming and sealing stages on powder, granule and snack lines. For pouches, a horizontal form-fill-seal (HFFS) machine forms the pack from film and a horizontal fill-seal machine fills pre-made pouches.

A flow wrapper wraps individual solid products such as bars, biscuits and small parts in a continuous film, forming and sealing each pack in one pass. On a line it sits after the product infeed and before coding and cartoning.

A liquid line fills, caps and labels bottles in sequence. A filler-capper-labeller covers the filling, closing and labelling stages in one line, and a separate labelling machine can be added where the label format needs it.

A shrink sleeve labelling machine applies a printed film sleeve to a bottle, can or jar and shrinks it on in a tunnel. It adds the labelling stage to a line where the decoration has to cover the whole container.

At the end of a packaging line, a shrink wrapper groups bottles, cans or jars into multipacks with an L-bar, side bar or sleeve sealer and a shrink tunnel. Where packs leave the line in boxes, a cartoning machine does this job instead.

Other machines: cup fill and seal, tube fill and seal, can fill-seam, blister and clamshell and capsule filling machines each form or fill, and then seal, their own pack format in one unit.
A standalone packaging machine is enough when one step is the bottleneck and the steps either side can keep up by hand, for example a VFFS bagger fed by an operator whose bags are boxed manually. A complete packaging line makes sense when output is high enough that manual steps between machines slow the whole process, or when hygiene and consistency matter at every stage. Many manufacturers start with the machine that removes the biggest bottleneck and add dosing, coding or end-of-line equipment later, so choose the first machine with the rest of the line in mind.
| Consideration | One machine | Complete line |
|---|---|---|
| Output | Suits lower or growing volumes | Suits steady, higher volumes |
| Labour | Operators feed and pack by hand between steps | Manual handling between stages is removed |
| Floor space | Fits a smaller area | Needs room for conveyors and every stage |
| Upgrade path | Add stages as volumes grow | Planned as one system from the start |
The cost of a packaging line is set by what the line has to do, not by a list price. The main factors are the level of automation, the output you need, the product (powders, liquids and fragile items need different dosing and handling), the pack format, how many stages are joined together, and whether the machines are built in stainless steel for food or corrosive products. A quotation for a packaging line also covers installation, operator training and support. The packaging machine cost guide explains how each factor moves a quotation.
A packaging line is built from five stages, so start from the stage that holds your production back. Browse the packing machine catalogue to see which machines cover each stage, or request a quote with your product, pack format and target output, and we will recommend the machines for your line.
They can, but the machines need matching speeds, compatible controls and conveyors that hand packs from one machine to the next. Planning the line as one system, even when the machines are bought over time, avoids gaps between stages.
No. Most packaging lines are built up in steps. Automating the slowest stage first gives the largest gain, and later machines can be added if they are specified to match the first.
Often, yes. Changing format parts, doser settings or film lets one line pack different products or pack sizes. The changeover time and parts needed depend on how different the products are, so list every product when you ask for a quotation.
