Product Introduction
The DS180A-P-G-L Stripe Back Seal Packaging Machine is a fully automatic VFFS solution designed to package powders, granules/particles, and liquids on one shared platform. With an electric + pneumatic drive architecture and servo-controlled sealing and bag pulling, it delivers stable forming, accurate dosing, and clean back-seal pouch output at 30–50 bags per minute. The machine is built for flexible production: switch between powder screw metering, push-cup particle dosing, or optional liquid pump/piston systems according to material characteristics and target fill range. CE and CE/ISO9001 compliance, a 304 stainless-steel main structure, and an operator-friendly Siemens control system make it a reliable choice for factories that need multi-product capability without sacrificing speed, consistency, or sealing quality.
Product Advantages
One Platform for Powder, Granules, and Liquids
A single host machine supports three product types, reducing equipment duplication and floor-space cost. The platform can be configured with a servo-driven auger (powder), a pneumatic push-cup dosing unit (granules), or optional liquid metering devices (low-viscosity pumps or medium/high-viscosity ceramic piston rotary valve pump). This modular approach supports faster product launches and easier line planning.
Servo-Controlled Sealing and Bag Pulling for Consistent Pack Quality
Servo motor heat sealing and servo bag pulling provide repeatable pouch length control and stable sealing pressure, improving appearance and reducing rejects. Back-seal strip pouch output is optimized with defined sealing widths and patterned horizontal sealing, delivering a professional finish suitable for retail or industrial channels.
Accurate Dosing Across Small Fill Ranges
For powders, the CCL1-N servo auger system covers 0.2–30 g without changing screw attachments, minimizing changeover time while keeping dosing stable. For granules, the TB-30 push-cup device provides adjustable small-dose control with accuracy dependent on material flow characteristics. Liquid options support 0–100 ml for dilute or low-viscosity liquids and 0–30 ml for medium to high viscosity liquids with pneumatic precision control.
Industrial-Grade Controls and Components
The standard control suite combines a Siemens 7-inch color touch screen and Siemens PLC with bilingual operation (Chinese/English), error prompts, and self-diagnostics to simplify operation and maintenance. Temperature stability is managed by Yudian PID control (2 vertical + 2 horizontal sealing channels). SUNX101 photoelectric tracking supports stable film registration, while key electrical parts from Schneider or Omron enhance long-term reliability. Taiwan AIRTAC pneumatic components support smooth actuation and consistent dosing performance.
Operator-Friendly Setup and Safer Operation
Integrated manual correction helps align film and improve forming stability. A manual expansion-shaft film mounting device speeds film replacement and reduces setup errors. A Panasonic safety door switch supports safer operation during routine checks and adjustments.
Hygienic, Durable Construction
Exposed machine surfaces are primarily 304 stainless steel or aluminum alloy (excluding parts unsuitable for moving mechanisms), supporting corrosion resistance and easier cleaning. This structure is suitable for daily production environments where stability, sanitation, and durability are required.
