Cap-cavity honey filling and sealing line
Fill-seal line (closure cavities)
Doses honey into closure cavities with a servo volumetric piston or a peristaltic pump, then seals with foil.
[Filling lines]
Filling Lines for Pastes and Viscous Products
How a paste fills depends on its temperature, its particles and how it is fed. Tell us how it behaves at filling temperature and we configure the line around that.
[01]
Describe Your Product at Filling Temperature
A paste behaves differently warm, cold, stirred or still. We size the line from how the paste behaves at the filler. The label doesn't tell you that.
| Question | Why it matters |
|---|---|
| How thick is it at filling temperature, and does it change with temperature? | Thicker product needs positive dosing and may need a warm hopper. |
| Is it smooth, or does it contain seeds, pieces or fibers? | Particles decide nozzle and valve size and can limit which filler is suitable. |
| Does it hold air or trap bubbles? | Air shows up as short fills and bubbles in clear jars. |
| Does it string or drip after the nozzle closes? | Stringing dirties rims and caps, and affects the seal on foil-sealed containers. |
| Does it set, crystallize or skin over when it sits? | It limits how long product can sit in the hopper, and what you can leave in the line overnight. |
[02]
Product Feeding and Dosing Options
General engineering notes. Our honey pages list servo piston and peristaltic dosing, and our sauce cup page lists servo piston dosing.
| Approach | Commonly considered for | Watch points |
|---|---|---|
| Servo volumetric piston from a hopper | Thick, smooth to lightly textured products where each container needs a set volume. | Seals and valves must be cleaned; large particles can jam the valve. |
| Peristaltic pump | Sticky or delicate products where a simple product path simplifies cleaning. | Tubing is a wear part; output depends on tube size and viscosity. |
| Other positive-displacement pumps (such as rotary or gear types) | Products that need steady transfer to the filler. | Depends on how the product behaves. |
| Heated or stirred hopper | Products that thicken or set when cooled. | Heating is not assumed; engineering decides for each product. |

Containers, Closures and Downstream Handling
Wide-mouth jars suit thick products, because the big opening lets a thick stream in without trapping air. Narrow-neck bottles suit sauces and creams that still pour. Squeeze bottles add a nozzle and a cap that must be oriented before placing.
After the filler, the line tightens the cap, applies a label and may print a code. Our catalog has wrap-around labelers for round jars and bottles, glass or plastic, and notes that oil residue on glass can affect label adhesion.
Foil sealing is a separate station with its own container prep, used for cups and some jar rims. It appears in our cup and cap-cavity machines.

Viscous Product Examples from LINEVO PACK
These are the closest examples we have: viscous dosing into closures and cups, and a sauce bottle line. Filling thick product into your own bottles or jars is something we work out with you.

How Output Is Confirmed
We publish no speeds or accuracy figures for paste lines. Output depends on how fast the product can be dosed without air or stringing, on container size and on the slowest station in the line.
The proposal states output for the agreed product, container and stations. Commissioning on site runs the line empty first, then with product. Tell us what you need per shift and how many people will run the line.
[06]
Cleaning Between Product Runs
A paste leaves residue in the hopper, valve, pump, nozzle and drip tray. The more often you change product, the more easy cleaning matters. Quick-release fittings, short product paths and a hopper you can reach with a brush all help.
Our sauce cup filler is listed with a clean-in-place design. Whether that suits a bottle or jar line depends on the product. If your recipes include allergens or strong colors, tell us at the start, and plan for rinse water and product loss too.

Paste Lines by Application
Honey and sauces are described on their own pages with their own conditions.

Scope Boundaries
Every paste line is configured to your product and container and built to order. The table shows the usual split. Hopper, feed heating and particle size stay open until we know how your product behaves.

Common Questions
- 01What counts as a paste or viscous product here?
- Anything that doesn't pour freely: honey, many sauces, creams and similar products. There's no sharp line. What matters is viscosity at the filling temperature.
- 02Can you fill a product with particles?
- Sometimes. The size and hardness of the pieces decide which filler and valve can be used. Describe them and we'll assess.
- 03Does my product need to be heated?
- Maybe. Some products pour better warm and some set when cooled. Our engineers decide once they know your product, and we don't assume heating beforehand.
- 04Is a thick product filled into a jar or a bottle more easily?
- Usually a wide-mouth jar, because the opening is large. Narrow-neck bottles work if the product still flows through the nozzle.
- 05Do you offer foil-sealed cups for paste?
- Yes, in two formats. Our catalog lists a rotary sauce cup filler and a cap-cavity honey line that both use foil sealing. They differ from bottle and jar lines, so tell us on WhatsApp which container you actually use.
