Product Introduction
The DS450-4G/P/L Automatic Pouch Filling and Sealing Machine is a high-output solution developed for continuous, multi-lane production of small-dose sachets. Engineered around composite packaging films and a flexible dosing architecture, it can be configured for granular products, free-flowing powders, or liquids (selected according to your product and packaging requirements) with a practical filling range of 1–50 ml. A motor-crank heat-sealing bag pulling system, coordinated by encoder feedback, keeps film transport and sealing actions precisely synchronized, delivering stable bag length control, clean seal geometry, and dependable throughput across long shifts. With a maximum film width of 450 mm and standardized bag-making tooling, the machine supports scalable column layouts based on sachet size and lane configuration, making it a strong fit for both growing brands and established factories seeking repeatable, professional sachet quality.
Product Features
Consistent sealing quality with a refined seal profile
The horizontal seal is designed with an 8–10 mm sealing width and a single-sided diagonal mesh pattern (1 mm spacing) to improve bonding strength while maintaining an attractive appearance. The back seal is kept clean and tidy with a 4–6 mm width and no pattern, supporting a neat, premium presentation suitable for retail-ready sachets.
Encoder-synchronized film pulling for accurate forming
By combining a motor-crank heat-sealing pulling mechanism with encoder-controlled motion, the DS450-4G/P/L aligns film travel, sealing timing, and cutting rhythm to reduce bag length deviation and enhance repeatability. This structure helps stabilize output quality, especially in multi-column production where uniformity across lanes is critical.
Material and product versatility for multiple filling types
The machine is compatible with composite packaging materials and can be matched with suitable dosing systems for particles, powders, or liquids. For liquid sachets, an optional 1 mm horizontal sealing leak-proof line can be adopted to increase resistance to seepage during sealing, conveying, and handling, supporting more robust packaging performance.
Reliable tracking and durable electrical architecture
Printed film registration is supported by JULONG dual-color photoelectric tracking (“Ronic Eye”), enabling stable mark detection and consistent graphic alignment. Core electrical components are sourced from Schneider or OMRON, supporting dependable control performance, easier maintenance, and improved long-term stability in demanding production environments.
Neat cutting finish and consumer-friendly opening options
An independent round-corner cutting unit improves pack aesthetics and reduces sharp edges, with controlled trim waste of approximately 2–3 mm. To enhance user experience, the machine supports point-shaped easy-tear or double easy-tear designs, implemented via an independent tear device to deliver clean, convenient opening performance.
Safety-focused design for daily operation
Standard safety provisions include three-color alarm lights, Panasonic safety door detection switches, emergency stop switches, and clear safety signage at heating zones and mechanical action areas. These features help reduce operational risk and support safer routine operation, cleaning, and maintenance.

Application Fields
The DS450-4G/P/L is ideal for manufacturers producing small-dose sachets where seal reliability, accurate registration, and consistent cutting quality directly impact product presentation and line efficiency. Typical applications include single-serve liquid samples and concentrates, sauces and flavorings, seasoning powders, beverage additives, nutraceutical powders, granular ingredients, and other small-volume consumer or industrial packs. With composite-film compatibility, configurable filling systems for particles/powders/liquids, and a column layout that scales with sachet dimensions, it integrates smoothly into modern packaging lines that require stable operation, repeatable pouch quality, and dependable multi-lane output.
