8-Lane 3-Side-Seal Liquid Sachet Packing Machine
Share to:
This is an 8-lane Liquid Packaging Machine for Tomato Sauce and Honey, which can automatically complete the dosing, bagging, filling and sealing of liquid/paste, suitable for beverage, sauce, daily chemicals, etc., to achieve high efficiency in batch packaging.
Machine Overview and Functional Description
The 8-lane Liquid Packaging Machine is specially designed for batch packaging of fluids/pastes, with core functions centering on high efficiency, precision and stability. 8-lane parallel structure synchronously completes bag making, filling and sealing, which improves productivity several times compared with the single-lane model, and it is suitable for the large-scale production of the food, cosmetic and pharmaceutical industries (e.g., beverage strips, sauce packets, lotion bags). Built-in high-precision metering pump for precise flow control, anti-drip filling head to avoid material waste, compatible with thin liquids and viscous pastes, to ensure the same dosage per bag. Reliable sealing: the packaging film is folded into 8 lanes of bag embryo, heat sealing the two sides and bottom edge first (pre-seal three sides), sealing the top after filling, the three side sealing structure saves the film and seals firmly, effectively preventing moisture and leakage. PLC + touch screen support parameter setting (bag length, speed, filling volume), real-time monitoring of the operating status, lack of film, clogging and other abnormalities automatically alarm; modular design to achieve multi-specification rapid production change. Food-grade stainless steel body in line with health standards, modular layout of key components, easy cleaning and maintenance to extend the life of the equipment. From juice, shampoo to oral liquid, the equipment with fully automated process and multi-column advantage, for liquid products sachet packaging to provide efficient solutions.

FAQs
- What are the core advantages of 8-lane parallel design over traditional single machine?
The 8-lane structure realizes the superposition of multi-line production capacity through synchronous operation, which greatly shortens the batch production cycle compared with the traditional single machine; the independent metering and heat sealing system of each column is controlled by PLC, which ensures that the bag size and filling volume of the 8 lanes are consistent and avoids the accumulation of error in the production of multiple batches by a single machine; at the same time, multiple columns share the unwinding and transmission system, which reduces the footprint of the equipment and the energy consumption, and achieves the triple improvement of “high efficiency capacity + precise control + cost optimization” by the intensive design. “High efficiency capacity + precise control + cost optimization” triple enhancement.
- How to realize the sealing and leakage prevention of three-side sealing?
Adopting precise heat sealing system, pre-seal both sides of the bag and the bottom edge first (forming a three-side pre-seal), and then seal the top edge after filling; the heat sealing temperature, pressure, and time are precisely regulated, and it is suitable for composite film such as PET/PE, ensuring a firm seal, effectively blocking moisture and air, and guaranteeing the sealing of the contents.
- Is it convenient to switch between different packaging specifications?
Relying on PLC intelligent control system, bag length, filling volume and other parameters can be set by one key, modularized mechanical structure to support rapid change of production, without complex debugging can be adapted to multiple specifications of three-side sealing packaging to meet the needs of small batch and multi-species production, to enhance the flexibility of the production line.
- Is the daily maintenance cost of the equipment high?
The core components adopt modular design, and it is convenient to replace the heat sealing knives, metering pumps and other wear parts; the equipment has built-in fault self-test and early warning function, and the daily maintenance is mainly based on cleaning and lubrication, so there is no hygienic dead corner in the structure, which reduces the cost of labor and spare parts, and guarantees the continuous and stable operation.
- Does it meet the hygiene standard of food/pharmaceutical industry?
The parts in contact with materials are made of food-grade stainless steel, and the structure of the whole machine follows hygienic design specifications (such as rounded corners, easy to dismantle and clean), which meets the requirements of production certification in the food and pharmaceutical industries, effectively avoids contamination of the materials and ensures product safety.
