Double-Row Irregular Premade Bag Packing Machine (DS350F/N)
The DS350F/N is a double-row premade bag packing machine engineered for high-efficiency, small-dose packaging of powders, granules, and liquid products. Designed around stable film control, precise dosing, and dependable sealing, it delivers consistent four-side sealed sachets while supporting irregular/custom “alien” bag shapes for stronger shelf differentiation. All product-contact parts are manufactured in 304 stainless steel to meet hygiene and durability requirements, making the DS350F/N a practical solution for brands seeking compact automation, fast changeovers, and reliable output in everyday production.
Product Features
Double-row operation for higher throughput: Two synchronized lanes run forming, filling, sealing, and cutting in parallel, improving productivity without sacrificing sealing uniformity or pack appearance—ideal for sample packs and retail sachets.
Supports irregular and custom bag formats: In addition to standard four-side sealing, the machine accommodates customized “alien” bag designs, helping premium or promotional products stand out while maintaining stable sealing strength.
Stable forming and film guidance: V-shaped forming structure with adjustable film width improves bag shaping consistency and reduces film deviation during continuous operation, supporting better registration and smoother production.
Designed for small-dose accuracy: Optimized for 1–20 g metering, the DS350F/N delivers controlled dosing performance across a broad range of powders, particles, and liquids. Accuracy depends on material characteristics, flowability, and target weight, enabling both trial-size and commercial sachet production.
Industrial control system for easier operation: A Siemens 7-inch color touchscreen paired with a Siemens PLC offers intuitive parameter setting, alarm prompts, and self-diagnostics, reducing operator dependency and shortening changeover time between different pack sizes and materials.
Consistent four-side sealing quality: Cylinder-driven horizontal sealing combined with dual-loop PID temperature control (Yudian) supports stable heat management across composite films, improving seal strength consistency and reducing the risk of weak seals or overheating.
Reliable components for long service life: Taiwan AIRTAC pneumatic components, together with Schneider or Omron electrical parts, provide dependable performance for extended daily operation and easier maintenance in factory environments.
Optional high-viscosity liquid filling compatibility: When configured with the optional UBA high-viscosity filler, the machine can handle gels and viscous liquids with improved stability, helping reduce dripping, stringing, and dosage fluctuation for premium liquid sachets.
