How to Choose a 4-Lane Liquid Sachet Packing Machine for Honey and Sauce
What Should You Check Before Buying a 4-Lane Liquid Sachet Packing Machine?
A 4-lane liquid sachet packing machine produces multiple sachets in parallel. It may be a suitable option for manufacturers packaging single-serve honey, syrup, sauces and other liquid products, but the number of lanes alone does not determine whether a machine fits a production line.
Before requesting a quotation, define four things: the product being filled, the finished sachet format, the required output and the packaging film. These details help the manufacturer recommend a configuration that can be tested against your actual production requirements.
1. Identify the Product Before Selecting the Machine
Start with the liquid itself rather than the machine's advertised speed.
Honey may flow slowly, while a thin beverage liquid may flow quickly or create splashing. Ketchup and chili sauce may contain suspended ingredients. Cosmetic lotions can have different viscosities and cleaning requirements from food products.
Provide the manufacturer with the product name, target filling quantity, viscosity information if available, operating temperature and details of any particles. If the product changes significantly between batches, explain that as well.
A machine that handles one liquid successfully should not automatically be assumed suitable for every product in your factory.
2. Confirm the Required Sachet Format
The sealing format determines how the film is formed and where the seals are created. Back-seal and four-side-seal sachets have different structures, so they should not be treated as interchangeable machine configurations.
Before choosing a machine, send a finished sachet sample or packaging drawing. Confirm the sealing format, sachet width, sachet length and film specifications with the supplier.
If the sachet requires a printed logo, batch number or expiry date, discuss the artwork and coding requirements before finalizing the equipment.
3. Select the Filling System for Your Liquid
The filling system should match the liquid's flow behavior, target quantity and cleaning requirements.
INNOV's current product information lists piston, peristaltic, ceramic and rotary pump options. However, the most appropriate pump cannot be determined from the product name alone.
Ask the supplier to evaluate the actual liquid and demonstrate:
-
Whether the target filling quantity can be achieved consistently
-
Whether the product drips after filling
-
Whether residue reaches the sealing area
-
Whether product-contact parts can be cleaned as required
These observations are more useful than selecting a pump based only on a general description.
4. Evaluate Production Output Under Real Conditions
A four-lane configuration allows several sachets to be produced simultaneously. The actual output still depends on the selected machine, filling volume, sachet dimensions, product characteristics and operating conditions.
Ask the manufacturer to identify the conditions behind any quoted speed. Ideally, conduct a test using your product and film, then count the acceptable finished sachets produced over a defined period.
A theoretical speed is useful for preliminary planning, but it should not be treated as a guaranteed full-shift production rate.
5. Check Changeover and Maintenance Requirements
If your factory packages several liquids or sachet sizes, cleaning and changeover can affect production efficiency.
Before ordering, ask which product-contact components need cleaning, which parts may require adjustment when changing formats, and what routine maintenance the machine needs. Also confirm the availability of spare parts and operator training.
A Practical Machine Selection Checklist
Prepare these details before requesting a quotation:
| Information | What to provide |
|---|---|
| Product | Name, viscosity and particle characteristics |
| Filling quantity | Target volume or weight per sachet |
| Sachet format | Back seal, four-side seal or another specified format |
| Dimensions | Finished sachet width and length |
| Film | Material structure, thickness and available roll specifications |
| Production target | Required acceptable sachets per hour or shift |
| Additional functions | Date coding, printing or production-line integration |
Frequently Asked Questions
Is a four-lane machine always faster than a single-lane machine?
Four lanes allow parallel production, but actual output depends on the configuration and operating conditions of both machines. Compare tested acceptable output rather than lane count alone.
Can one machine package honey and chili sauce?
Possibly, but both products should be evaluated. Differences in viscosity, suspended particles, residue and cleaning requirements may affect the filling configuration.
What should I send for a quotation?
Send the liquid details, filling quantity, sachet dimensions, required sealing format, film specifications and target output. A finished sachet sample or product sample can help the supplier assess compatibility.
Discuss Your Liquid Packaging Requirements with INNOV
INNOV can evaluate your product, sachet format and production target to help identify a suitable machine configuration. Provide your packaging requirements first so the proposed solution can be assessed against the actual application.
