Product Overview
The DS180/2 Double-Row Back-Sealing Automatic Packaging Machine is a compact, high-throughput sachet solution engineered for clean, consistent, and efficient small-dose packaging of particles, powders, and liquids. Designed around a multi-row forming concept, it integrates film forming, precise dosing, photoelectric tracking, heat sealing, and cutting in one stable platform to support continuous production with uniform bag appearance and dependable seal integrity. All product-contact parts are manufactured in 304 stainless steel to meet hygiene expectations in food, pharmaceutical, and daily chemical environments while improving corrosion resistance and service life. With a double-row layout and a collar forming structure up to 180 mm, the DS180/2 is ideal for manufacturers seeking increased capacity without sacrificing packaging accuracy, seal quality, or operational stability.
Key Features
Double-Row Architecture for Higher Output
By producing two rows simultaneously, the DS180/2 delivers significantly improved productivity in a footprint suited to modern workshops. Stable mechanical forming and sealing performance supports continuous operation at 30–50 bags per column per minute, enabling scalable output for growing production demands.
Back-Sealing Structure with Clean Presentation
The back-sealing design adopts twisted-edge adhesive sealing to create neat, secure sachets suitable for retail presentation and downstream cartoning. Straight horizontal sealing with 1.2 mm spacing supports a uniform seal pattern, while controlled sealing widths (5 mm vertical, 8 mm horizontal) enhance sealing strength and repeatability across long runs.
Photoelectric Tracking for Accurate Print Registration
An integrated photoelectric eye detects film marks to maintain stable alignment on printed roll film. This improves bag-length consistency, reduces mis-cutting and rework, and helps minimize film waste—especially important when running branded packaging materials or multi-color designs.
Stable Film Pulling and Bag Length Control
Variable-frequency motor bag pulling ensures smooth film transport across different speeds and material types. The controlled pulling motion helps maintain consistent bag length and forming stability, supporting reliable sealing and cutting even during extended production shifts.
Smart PLC Control with Error Prompting and Temperature Precision
A text display operation interface combined with an OMRON PLC provides efficient parameter setup and stable process control. Built-in fault prompting and self-diagnosis improve uptime by enabling faster troubleshooting. Dual PID temperature control (OMRON) maintains precise sealing temperatures for common composite films, improving yield and reducing seal defects caused by temperature drift.
Flexible Dosing Configurations for Different Product Forms
To match diverse materials and flow characteristics, the DS180/2 can be configured with dedicated metering systems for granules/particles, powders, or liquids. Each metering option is designed for repeatable filling performance, and all product-contact components remain 304 stainless steel to support hygienic operation and easy cleaning.
Industrial Pneumatics and Durable Construction
Taiwan AIRTAC pneumatic components provide stable actuation under factory conditions. Blade separation (without flash device) and pattern cutting deliver clean edges and consistent aesthetics, supporting high-quality sachet output suitable for automated downstream handling.
