Key Features and Machine Characteristics

• PLC Servo Drive System with Touchscreen Control: Advanced PLC servo drive system with large display touchscreen maximizes overall machine control precision, reliability, and intelligent operation. The servo-driven mechanism ensures accurate bag length control, consistent sealing pressure, and precise product positioning, reducing material waste and improving packaging quality compared to conventional cam-driven systems.
• Multi-Product Parameter Storage and Quick Changeover: Touchscreen interface stores packaging process parameters for multiple products with synchronized backup functionality. When changing products, operators can instantly recall saved parameters without manual reconfiguration, reducing changeover time from hours to minutes and improving production flexibility for manufacturers handling diverse granular product portfolios.
• High-Precision Weighing System (≤±1% Accuracy): Integrated weighing system delivers ≤±1% accuracy for consistent product dosing across all bag sizes and granular materials. This precision weighing capability minimizes product giveaway, reduces material costs, ensures regulatory compliance for pharmaceutical and food products, and maintains consumer confidence through consistent package weights.
• Full 304 Stainless Steel Construction: Complete 304 stainless steel body construction ensures aesthetic appeal, exceptional durability, and compliance with food safety and pharmaceutical GMP standards. The corrosion-resistant stainless steel design facilitates thorough cleaning and sanitation, prevents product contamination, and provides long service life even in demanding production environments with frequent washdowns.
• Comprehensive Standard Function Configuration: Equipped with color mark detection for precise bag positioning and registration, standard ribbon coding for date and batch printing, and sponge air exhaust for optimal bag sealing and product freshness. These integrated features eliminate the need for separate auxiliary equipment, reducing capital investment and simplifying production line integration.
• 3-Side Seal Bag Format with Multiple Cut Options: Produces three-side seal bags with serrated cut for easy opening or flat cut with easy-tear notch for consumer convenience. The 3-side seal format provides excellent product visibility for retail display, efficient material usage compared to four-side seal bags, and versatile presentation options for various market segments.
• Enterprise-Grade Safety Protection: Comprehensive safety guards and interlocks meet enterprise safety management requirements, protecting operators from moving parts, hot sealing components, and electrical hazards. The integrated safety system prevents accidental operation, reduces workplace injury risks, and ensures compliance with occupational health and safety regulations.
• Fully Automated Packaging Process: When configured with appropriate metering and conveying systems based on product properties, this VFFS machine automatically completes the entire packaging process including product metering, filling, three-side seal bag forming, gas flushing or air evacuation, date printing, and automatic counting. This complete automation reduces labor costs, improves packaging consistency, and increases production efficiency.
