Double-Row Irregular Premade Bag Packing Machine (DS350F/N)
The DS350F/N double-row irregular packaging machine is designed for high-efficiency, small-dose packing of powders, particles, and liquids. Built with 304 stainless steel on all product-contact parts, it supports four-side sealing with stable film control and accurate metering for 1–20 g packs. With an output of 20–40 bags per minute (depending on material characteristics and dosage), the machine is ideal for manufacturers who need flexible bag formats, consistent seals, and reliable automation in a compact production footprint.
Product Advantages
Double-row output for higher productivity: Two-lane operation increases throughput while maintaining consistent forming, filling, and sealing performance.
Flexible packaging for irregular/custom bags: Supports “alien” customization and four-side sealing, helping brands create differentiated package shapes and premium shelf impact.
Stable forming and film handling: V-shaped forming with adjustable film width improves bag shaping and reduces film deviation during continuous operation.
Accurate and controllable dosing: Designed for small packs from 1–20 g with packaging accuracy ranging from ±1% to ±10% (material-dependent), suitable for both trial packs and retail sachets.
Industrial-grade control and diagnostics: Siemens 7-inch color touch screen with Siemens PLC provides alarm prompts, self-diagnostics, and intuitive parameter setting for faster changeovers.
Consistent sealing performance: Cylinder-driven horizontal sealing and dual-way PID temperature control (Yudian) help achieve uniform seal strength across composite films.
Reliable components for long service life: Taiwan AIRTAC pneumatic components, plus Schneider or Omron electrical parts, deliver dependable performance in demanding production environments.
Optimized for viscous filling (optional): Compatible with UBA high-viscosity filler for liquid/gel products, improving dosing stability and reducing stringing or dripping.
