The DS180/2 Double-Row Back-Sealing Automatic Packaging Machine is designed for efficient, stable, and hygienic sachet production for particles, powders, and liquids. Built with 304 stainless steel on all product-contact parts, it integrates film forming, precise dosing, sealing, and cutting into a compact multi-row system. With a multi-row collar forming structure (≤180 mm) and dependable photoelectric tracking, it delivers consistent bag shape and seal quality for high-throughput small-dose packaging.
Product Advantages
Double-Row Output for Higher Productivity
The double-row configuration increases throughput while maintaining stable forming and sealing. The machine supports high-speed continuous operation at 30–50 bags per column per minute, making it suitable for scalable production lines requiring reliable performance.
Back Sealing with Clean, Firm Seal Quality
The back-sealing structure uses twisted-edge adhesive sealing to create tidy, secure sachets. Straight horizontal sealing with 1.2 mm spacing supports uniform seal appearance, while controlled sealing widths (5 mm vertical, 8 mm horizontal) improve sealing strength and consistency.
Accurate Tracking and Stable Bag Length Control
Equipped with a photoelectric eye for film mark detection, the system improves alignment accuracy for printed films and reduces material waste. A variable-frequency motor bag-pulling method helps maintain consistent bag length and smooth film transport at different speeds.
Smart Control, Fault Prompting, and Temperature Precision
The control architecture combines text display operation with an OMRON PLC, enabling error prompting and self-diagnosis. Dual PID temperature control (OMRON) supports stable heat sealing across different composite films, improving yield and reducing rework during long production runs.
Flexible Metering Options for Multi-Material Packaging
To match different product types, the machine can be configured with dedicated metering devices for granules/particles, powders, or liquids. Each option is designed for repeatable filling performance, and all material-contact components use 304 stainless steel for improved hygiene and corrosion resistance.
Industrial Pneumatics and Durable Build
With Taiwan AIRTAC pneumatic components, stable air pressure operation, and a rigid structure, the system is engineered for factory environments. The blade separation method (without flash device) and pattern cutting help deliver neat bag edges and consistent presentation.
