Automatic Vertical Liquid Sachet Packing Machine for Efficient Pouch Packaging

Machine Introduction

This machine is a high-performance tool in modern packaging industry, specially designed to efficiently, accurately, and hygienically fill liquids, pastes, and sauces (such as shampoo, soy sauce, edible oil, juice, pesticides, lubricants, etc.) into pre-formed plastic film bags and complete the sealing process. Its core working principle can be summarized as: “bag forming – filling – sealing,” continuously and automatically completed in an integrated operation.

Technical Parameters

What This Machine Does

The Ry-70YLB-L is a vertical form-fill-seal machine specialized for packaging liquids, pastes, and sauces into pre-formed sachet pouches. It handles products ranging from shampoo and soy sauce to edible oil, fruit juice, pesticides, and industrial lubricants with fill volumes from 1 to 500ml. The machine continuously forms bags from roll stock film, fills them with precisely measured product, and seals them in a single integrated operation at speeds of 30 to 80 bags per minute.

How Vertical Liquid Sachet Packaging Works

The film roll feeds into the machine and passes through a forming collar that shapes it into a continuous tube. Vertical sealing jaws create the back seal along the tube's length, while horizontal sealing jaws seal the bottom of each sachet. The liquid or paste product is then pumped through a filling nozzle into the formed pouch with precise volumetric dosing. Once filled, the horizontal jaws seal the top of the sachet and simultaneously form the bottom seal of the next sachet. A cutting knife separates the finished sachet, and it drops to the output conveyor. The PLC system coordinates film feed, filling, sealing, and cutting timing to maintain consistent sachet quality at production speeds.

Key Features for Liquid Packaging Operations

1. High automation and efficiency: The entire bag-forming, filling, and sealing cycle runs continuously without operator intervention, reducing labor costs and minimizing human contact with product.
2. Precise volumetric dosing: A piston or pump-based measuring system delivers consistent fill volumes across the entire production range, critical for regulated products like pharmaceuticals and food additives.
3. Reliable sealing for liquid products: Temperature-controlled sealing jaws produce hermetic seals that prevent leakage during transport and storage, even with thin-viscosity liquids.
4. Flexible format changes: Sachet size and fill volume adjustments can be made through the touch screen interface without extensive mechanical reconfiguration.
5. Hygiene and safety compliance: Product contact surfaces use food-grade stainless steel, and the machine design follows sanitary construction principles with accessible cleaning points for washdown procedures.
6. Intelligent monitoring: The PLC system provides real-time diagnostics, production counting, and alarm functions that alert operators to film breaks, low product supply, or sealing temperature deviations.

Applications Across Industries

In the food industry, this machine packages soy sauce, ketchup, cooking oil, honey, juice concentrates, and liquid flavorings. Personal care applications include shampoo sachets, conditioner samples, body wash, and hand sanitizer. The chemical industry uses it for liquid detergent, pesticide formulations, lubricant sachets, and industrial adhesive packaging. Pharmaceutical applications cover liquid medication doses, antiseptic solutions, and oral rehydration salts in liquid form. The machine's ability to handle viscosities from thin liquids to thick pastes makes it a versatile choice for manufacturers with diverse product lines.

Material Construction and Compliance

The machine frame is constructed from SUS304 stainless steel with product contact parts available in SUS316 stainless steel for applications involving corrosive liquids. The design complies with GMP-oriented production requirements and supports CE certification for international export. The PLC control system uses quality imported components for reliable long-term operation in demanding production environments.

After-Sales Support

Each machine includes operation manuals and installation videos. Online technical support and remote troubleshooting are available, with lifetime technical assistance provided as standard. Overseas engineer service can be arranged for on-site installation and operator training. Standard delivery time is 7 to 15 working days for single machines and 20 to 30 working days for complete packaging lines.
