Product Details

Product Introduction

The Automatic Pouch Filling and Sealing Machine represents a pinnacle of efficiency and precision in modern liquid sachet packaging. Engineered for high-performance production environments, this machine seamlessly integrates advanced automation with robust stainless-steel construction. Its core function consolidates the entire packaging process—film forming, precise dosing, bag pulling, cutting, and sealing—into a single, streamlined operation governed by a reliable PLC control system. Designed to operate within a compact bag-making range, it consistently produces neat, uniform, and secure pouches. This capability empowers manufacturers to achieve standardized packaging quality, significantly boost production throughput, and enhance overall labor efficiency. Featuring a variable-frequency motor crank structure paired with heat-sealed bag pulling technology, the machine ensures exceptional motion control stability and smooth film handling. This design supports continuous, long-shift operation while delivering dependable sealing performance, making it an indispensable asset for scalable production.

Product Features

Precision Dosing for Unwavering Consistency

At the heart of this machine lies its highly accurate dosing system, engineered as a precise measurement solution. It achieves a measurement accuracy ranging from ±1% to ±10%, adaptable based on the specific packaging materials and fill volumes required. This precise control is instrumental in minimizing product overfill, drastically reducing material waste, and guaranteeing remarkable batch-to-batch consistency for a wide spectrum of liquid products.

Leak-Proof Sealing Engineered for Liquids

Specifically tailored to meet the stringent demands of liquid packaging, this equipment incorporates a specialized horizontal sealing system. It features a 1mm leak-proof sealing line, a critical design element for liquid containment that significantly enhances seal integrity. This robust sealing dramatically lowers the risk of leakage throughout the product’s lifecycle—from handling and transportation to retail display. Utilizing a twisted-edge adhesive sealing technique, the machine further improves closure stability and delivers a polished, professional pouch appearance.

Stable and Accurate Film Tracking

Equipped with a high-precision JULONG dual-color photoelectric eye, the machine provides exceptional mark detection capabilities. This ensures accurate and consistent bag positioning, which is fundamental for achieving uniform pouch lengths and perfectly aligned seals. This feature is particularly valuable when processing pre-printed films, safeguarding brand integrity and ensuring a premium presentation on the shelf.

Versatile Cutting for Customized Finishes

The machine offers superior finishing flexibility through its independent cutter system, which provides a choice between a clean flat cut or a consumer-friendly serrated cut, with a precise 3mm spacing between cutters. This adaptability allows producers to cater to diverse market preferences and product types. A consistent back sealing width of 5–10mm (without patterns) contributes to a tidy seam, while the system’s controlled pulling motion maintains optimal film tension. The result is a consistently professional and aesthetically pleasing pack presentation.

Industrial Durability and Automated Efficiency

Constructed from high-grade stainless steel, this automatic unit is built for longevity, hygiene, and repeatable performance in demanding factory and workshop environments. With an operational speed of 20 to 40 bags per minute, it effectively supports scalable production output. This high level of automation minimizes manual intervention, reduces operator workload, and optimizes overall production line efficiency.
