Multi-Lane Liquid and Paste Stick Pack Machine

Product Overview

This multi-lane stick pack machine is designed for packaging liquid and paste products into narrow back-sealed sachets. Depending on the selected machine width and sachet dimensions, the equipment can be configured with several parallel packaging lanes to increase total output within one integrated system.

The product is supplied from a storage tank or feeding system to the selected dosing pumps. Depending on viscosity and dosing requirements, the machine can be configured with piston pumps, peristaltic pumps, ceramic pumps, or rotary pumps. Each dosing path transfers a preset quantity of product into its corresponding sachet lane.

Roll-fed packaging film is aligned, divided, formed around the filling tubes, and pulled to the selected bag length. The machine then completes liquid filling, longitudinal back sealing, horizontal sealing, cutting, and finished-sachet discharge.

The equipment is suitable for food, beverage, personal-care, household-product, and contract-packaging factories. Final suitability depends on viscosity, temperature, foaming tendency, product corrosiveness, solid-particle content, required dose, film structure, and sealing performance.

Applications

This machine is suitable for pumpable liquids and pastes that can flow consistently through the selected dosing system and filling nozzles. Pump type, pipe diameter, tank design, and cleaning arrangement should be selected according to product viscosity and physical characteristics.

This machine is suitable for:

• Drinking water

Main Features

1. Flexible Multi-Lane Configuration

Different machine widths support several lane quantities, allowing the final configuration to be selected according to sachet width, film width, target output, and available production space.

2. Parallel Sachet Packaging

All active lanes perform dosing, filling, forming, sealing, and cutting simultaneously, increasing total output without requiring several separate single-lane packaging machines.

3. Multiple Pump Options

Piston, peristaltic, ceramic, or rotary pumps can be selected according to product viscosity, flow properties, dosing volume, hygiene requirements, and compatibility with the filling material.

4. Back-Sealed Stick Sachets

Each lane produces a narrow sachet with a longitudinal back seal, suitable for single-use portions of beverages, honey, sauces, gels, shampoo, and other liquids or pastes.

5. Servo Film-Pulling System

The servo-controlled film drive advances the packaging material according to the preset sachet length and coordinates film movement across the active packaging lanes.

6. Adjustable Sachet Length

The documented bag length can be adjusted from 50 to 180 mm, while sachet width is determined by the selected model, lane arrangement, and forming components.

7. PLC and Touch-Screen Control

The control system coordinates product dosing, film feeding, sealing temperature, cutting, and machine operation through a centralized operator interface.

8. Film Alignment and Monitoring

The documented film-correction and film-break monitoring functions help maintain roll-film position and can trigger an alarm or machine stop when abnormal feeding is detected.

9. Multiple Cutting Styles

Straight cutting, zigzag cutting, rounded cutting, and die-cut formats can be configured according to the required sachet appearance and opening method.

10. Stainless-Steel Machine Structure

The supplied brochure identifies a 304 stainless-steel machine structure, supporting routine cleaning and use in liquid and paste packaging environments.

Working Principle

Liquid or paste product is first supplied to the storage tank and transferred to the selected dosing system. Each packaging lane has a corresponding pump or filling path that dispenses the preset quantity through its filling nozzle.

Roll-fed packaging film is unwound and guided through the alignment system. The film is divided according to the selected lane quantity and directed into the individual bag-forming units. A servo-driven mechanism pulls the film downward to the preset sachet length.

Each forming unit shapes the film around its filling tube. The longitudinal sealing section produces the back seal, and the measured product is dispensed into the partially formed sachet. The horizontal sealing unit then closes the sachet ends.

Finally, the cutting mechanism separates or shapes the completed sachets before they are discharged for collection or downstream conveying.

Process Flow:

Product Feeding → Pump Dosing → Film Unwinding → Film Alignment → Film Splitting → Sachet Forming → Filling → Back Sealing → Horizontal Sealing → Cutting → Discharge

Machine Details

1. Product Storage Tank

The tank stores liquid or paste before filling and supplies the dosing system. Tank design should be matched to product viscosity, temperature, settling tendency, and cleaning requirements.

2. Pump Dosing System

The selected pump measures and transfers product to each filling lane. Pump type should be confirmed according to viscosity, filling volume, corrosiveness, and solid-particle content.

3. Multi-Lane Distribution Pipes

Separate pipes or dosing paths carry the measured product from the pump system to the corresponding filling nozzles in each packaging lane.

4. Film Unwinding Assembly

The roll holder and guide rollers supply packaging film continuously and maintain stable film movement toward the splitting and forming sections.

5. Film Alignment System

The correction structure helps maintain the correct lateral position of the film while it moves through the multi-lane packaging process.

6. Servo Film-Pulling Mechanism

The servo drive advances the film according to the selected sachet length and synchronizes film movement with the filling, sealing, and cutting cycle.

7. Multi-Lane Bag Formers

The forming units convert divided roll film into several narrow sachet lanes and guide each film section around its filling tube.

8. Longitudinal Back-Sealing Units

Each lane has a vertical sealing position that closes the rear seam after the film has been formed around the filling tube.

9. Horizontal Sealing and Cutting Unit

The horizontal jaws close the sachet ends, while the cutting mechanism separates or shapes the completed packages according to the selected configuration.

10. Touch-Screen Control Panel

The operator interface provides access to sachet length, sealing temperature, pump settings, operating speed, alarms, and machine start or stop controls.

Technical Parameters

Packaging & Shipping

The final packing method, number of shipping cases, packed dimensions, and gross weight depend on the selected machine width, lane quantity, pump-dosing system, storage tank, feeding arrangement, and downstream equipment.

Before shipment, the machine should be tested with the buyer’s approved product, target filling volume, sachet dimensions, packaging film, printed artwork, and cutting requirements. Pump operation, filling pipes, film alignment, sealing temperatures, cutting positions, alarms, and control functions should be checked against the confirmed order.

Product-contact parts should be cleaned before packing, while pipes, nozzles, pumps, and moving components should be secured to prevent damage during transportation.

The final packing method, shipping dimensions, and gross weight will be confirmed according to the selected machine configuration.
