Automatic Honey Sauce Liquid Sachet Packing Machine with Ceramic Pump & Laser Coding

The Automatic food liquid sachet packing machine fills and seals small-dose liquid products into flexible sachets — honey, sauces, syrups, edible oils, liquid seasonings, beverage concentrates. A ceramic plunger pump drives the fill.

Ceramic resists wear and chemical interaction better than metal alternatives — relevant for acidic sauces, enzyme-based condiments, or formulations with active ingredients that degrade standard pump contact surfaces over time. The plunger mechanism delivers a fixed volume per stroke regardless of how the product resists flow, which is what keeps fill weight consistent when product viscosity shifts between batches or across a long production run.

A servo-driven film feeding system controls pouch length. Servo actuation holds film tension consistent rather than running at a fixed speed — where tension variation would cause pouch length to drift across a run, the servo corrects continuously. Independent temperature control manages sealing across different film materials — back seal, three-side seal, and four-side seal formats each run without requiring a dedicated machine per style.

An optional laser coding system prints production dates, batch numbers, and traceability information permanently onto the packaging film during the sealing stage — at the unit level, which gives finer traceability than outer carton coding alone if a quality issue requires isolating a specific production run.

Machine Details

PLC Touchscreen Control

Filling volume, pouch length, production speed, and sealing parameters — all adjustable from one interface without stopping the line. Saved recipes mean switching between product specifications is a recall rather than a manual re-entry of parameters from scratch.

Ceramic Plunger Pump Filling System

The ceramic plunger delivers a fixed volume per stroke — the same volume every cycle regardless of how the product resists flow. Ceramic wears slower than metal under repeated cycling and resists chemical interaction with acidic or active food ingredients that would degrade a standard metal pump surface over time. For products sold by declared weight, that combination of mechanical consistency and material durability is what keeps fill accuracy from drifting as the machine accumulates run hours.

30L Food Grade Hopper

A 30-liter capacity reduces how often the hopper needs reloading during a continuous run. Optional heating and mixing functions maintain product temperature and viscosity between refills — relevant specifically for honey, syrup, and thick sauces, where ambient cooling between batches changes how the product flows through the pump and affects fill consistency.

Laser Coding System

Production dates, expiration dates, batch numbers, and traceability information print permanently onto the packaging film during the sealing stage — no ink, no consumables, no smearing risk on film surfaces where inkjet coding tends to fail. Sachet-level coding gives traceability down to the individual unit, which matters if a quality issue requires isolating a specific production run rather than pulling an entire shipment.

Servo Film Feeding Structure

A servo motor controls film transport speed and pouch length simultaneously. Servo actuation holds tension consistent rather than running at a fixed speed — where tension variation causes pouch length to drift across a run, the servo corrects in real time.

Independent Heat Sealing System

Vertical and horizontal sealing operate under separate temperature control. Different seal orientations on the same pouch often require different heat settings — running both at the same temperature produces a seal that's correctly formed in one direction and over- or under-heated in the other. Independent control removes that tradeoff.

Flexible Sachet Cutting System

Interchangeable cutting blades produce straight-cut, round-corner, patterned, and connected sachet designs. Format switches through blade replacement rather than machine reconfiguration — relevant for manufacturers running promotional packaging, market-specific formats, or multiple SKUs with different sachet styles on the same production line.

How Does the Liquid Sachet Packing Machine Work?

1. The operator fills the hopper with product and sets the required filling volume, pouch length and production parameters on the PLC touchscreen.
   
2. Packaging film is automatically fed by the servo-driven system and formed into sachets. The ceramic plunger pump accurately dispenses the preset amount of liquid into each pouch.
   
3. The machine then performs vertical and horizontal heat sealing before cutting the finished sachets. 
   
4. If equipped with the optional laser coder, production information is printed automatically during packaging, creating a continuous, efficient packaging process.

Frequently Asked Questions

What products can this machine package?

Honey, syrup, sauces, cooking oil, liquid seasonings, beverage concentrates, condensed milk — food liquids and semi-liquids generally fall within range. If it flows through a ceramic plunger pump without bridging or requiring elevated temperature to move at all, the filling system handles it.

What filling range does the machine support?

Standard range is 1 to 50 ml. Wider or narrower ranges can be specified for applications outside that window — confirm the target fill volume before ordering rather than adjusting after delivery.

What pouch styles can the machine produce?

Back seal, three-side seal, and four-side seal sachets. Round-corner and other cutting styles are available through interchangeable blades — format switches through blade replacement rather than machine reconfiguration.

Can the machine print production dates and batch numbers?

Yes, as an optional laser coding system. Production dates, expiration dates, and batch numbers print permanently onto the packaging film during the sealing stage — no ink, no consumables, no smearing risk on film surfaces where inkjet coding tends to fail. Coding happens at the unit level, which gives finer traceability than outer carton coding alone.

Is the machine suitable for viscous products?

Yes. The ceramic plunger pump delivers a fixed volume per stroke regardless of how the product resists flow — which is what keeps fill weight consistent when viscosity shifts between batches or across a long run. The optional heated mixing hopper maintains product temperature between refills for honey, syrup, condensed milk, and thick sauces where ambient cooling changes flow behavior before it reaches the pump.

Can the machine be customized?

Yes. Filling range, pouch size, sealing style, hopper configuration, and coding system can all be specified at order rather than worked around after delivery.
