flow wrap package

Definition & Process:
Flow wrap packaging (horizontal form-fill-seal) is an automated method where products are wrapped in flexible films with precision end seals. The process involves film forming, product insertion, longitudinal sealing, end sealing, and cutting.

Key Technical Specifications:

1. Machine Components:
   • Film unwinding system with tension control
   • Forming collar/shoulder (adjustable angles)
   • Longitudinal sealing system (constant temperature)
   • Cross sealing jaws (servo-controlled)
   • Precision cutting mechanism
2. Performance Parameters:
   • Speed range: 50-800 packages/minute
   • Film width handling: 150-650mm
   • Product length capacity: 30-500mm
   • Package thickness: 5-150mm
   • Power requirement: 3-10kW (380V)
3. Material Compatibility:
   • Films: BOPP, PET, PE, metallized, laminated
   • Thickness range: 15-80μm
   • Printability: Up to 10-color flexo printing

Quality Control Systems:

• Integrated checkweigher (±0.5g accuracy)
• Metal detection (Fe 0.3mm, Non-Fe 0.5mm)
• Vision inspection (200fps camera speed)
• Automatic rejection systems

Advanced Features:

• Quick changeover system (<5 minutes)
• Nitrogen flushing capability (for MAP)
• IoT-enabled performance monitoring
• Predictive maintenance alerts
• Energy-saving mode (up to 30% reduction)

Industry Applications:

1. Food:
   • Bakery products
   • Confectionery
   • Snack foods
   • Frozen goods
2. Non-Food:
   • Pharmaceuticals
   • Medical devices
   • Hardware items
   • Stationery products

Cost Structure:

• Entry-level: $50,000-$100,000
• Mid-range: $100,000-$250,000
• High-performance: $250,000-$500,000+

Maintenance Protocol:

1. Daily:
   • Seal jaw cleaning
   • Film path inspection
2. Weekly:
   • Chain lubrication
   • Sensor calibration
3. Monthly:
   • Servo motor checks
   • Mechanical alignment

Technical Advantages:

1. Higher packaging speeds vs vertical systems
2. Better material utilization (5-15% savings)
3. Superior package integrity
4. Flexible format changes
5. Lower operational costs

Regulatory Compliance:

• CE Marking
• FDA 21 CFR Part 11
• EHEDG certification
• ISO 9001:2015
