The DS450-4G/P/L Automatic Pouch Packing Machine is a high-performance form-fill-seal (FFS) system designed for continuous, accurate, and hygienic small-sachet production. Engineered for industrial-duty operation, it integrates stable mechanical sealing, precise film tracking, and dependable electronic control to deliver uniform pouch forming, consistent filling, firm sealing, and clean cutting. Optimized for composite packaging films, the DS450-4G/P/L is especially effective for liquid and small-dose products where seal integrity, pouch appearance, and repeatability are critical to brand presentation and downstream handling.
Product Introduction
Built for demanding packaging lines, the DS450-4G/P/L focuses on long-term stability and consistent output quality. The machine forms pouches from roll film, performs accurate positioning through photoelectric tracking, and completes horizontal/back sealing with controlled heat and pressure. A dedicated leak-proof line option enhances performance for liquid sachets, while round-corner cutting improves the finished look and reduces edge irregularities. With industrial-grade electrical components and a safety-oriented layout, the equipment supports reliable production in multi-shift environments and helps operators maintain stable performance with straightforward monitoring and maintenance access.
Product Features
High-precision tracking for neat pouch registration: A dual-color photoelectric electronic eye improves printed mark recognition and tracking stability, helping maintain consistent pouch positioning and reducing misalignment waste.
Stable sealing and pulling mechanism: The motor-crank heat-sealing and bag-pulling structure, coordinated by encoder-controlled sealing action, provides repeatable motion control and consistent sealing behavior—supporting uniform pouch length, clean transitions, and steady operation.
Enhanced sealing reliability for liquids: A 1mm horizontal leak-proof line (for liquid applications) strengthens sealing confidence and helps reduce leakage risk, supporting products that are sensitive to seal defects during transport or storage.
Clean, premium-looking cutting finish: Round-corner cutting with an independent cutting device delivers a refined pouch appearance and stable cut quality. Edge waste is controlled at approximately 2–3mm, helping balance aesthetics and film utilization.
Industrial electrical architecture: Key electrical components are configured with Schneider or OMRON parts to support stable control performance, strong availability, and easier long-term servicing.
Safety-focused machine design: The system includes three-color alarm indication, safety door detection switches, and an emergency stop function. Clear identification of heating zones and mechanical motion areas helps improve operational safety and reduces maintenance risk.
Composite film compatibility: Designed for composite packaging materials commonly used for sachets, supporting consistent forming and sealing performance across typical laminated structures used in food, pharma, daily chemical, and industrial markets.

Application Industries
The DS450-4G/P/L is designed for forming, filling, sealing, and cutting small sachets that require consistent sealing strength, accurate registration, and a clean finished appearance. Typical applications include food and beverage ingredients (seasonings, condiments, additives, sample packs), pharmaceutical and healthcare products requiring controlled small-dose packaging, daily chemical and cosmetic liquids (essences, lotions, trial-size products), and chemical or industrial liquids and fine-flowing materials where dependable sealing performance is essential. With composite film support and a leak-proof sealing line option for liquid sachets, it is well-suited for high-frequency production tasks where stability, seal integrity, and professional pouch presentation are key quality targets.
