1. Product Introduction

The FFS tubular film machine for 25kg seed packaging integrates advanced servo technology (±0.2% weighing accuracy) with seed-specific features including:

Nitrogen flushing system (O₂<0.5%) for germination preservation

Anti-static film handling (150-200μm multilayer co-extruded PE/PP)

Dust-proof screw feeder for delicate seed varieties

ATEX-certified components for combustible dust environments

Key technical parameters:

• Capacity: 400-500 bags/hour (25kg standard)

• Film width: 600-1000mm adjustable

• Sealing: Dual hot-bar with cool seal reinforcement

• Compliance: ISO 9001, CE, and ISTA seed packaging standards

3. Operational Manual

3.1 Pre-Production Setup

Film loading:

Mount 1.2m diameter anti-static film rolls

Thread through laser-aligned dancer rollers

Parameter configuration:

Set bag dimensions (standard 600×900mm)

Input seed-specific parameters:

Bulk density: 0.65-0.75g/cm³ (adjustable)

3.2 Production Cycle

Phase 1: Tube formation → Bottom seal (160°C)

Phase 2: Loss-in-weight filling (25kg±10g)

Phase 3: Nitrogen purge (5L/min) → Top sealing

Phase 4: Automated quality rejection system checks:

Weight tolerance (±0.1%)

Seal integrity (5kg pull test)

3.3 Maintenance Protocol

Daily:

Clean residual seeds with compressed air (≤0.3MPa)

Inspect film tension sensors

Monthly:

Replace wear parts:

Screw feeder liner (UHMW-PE material)

Sealing jaw PTFE strips

Recalibrate load cells with 25kg test weights

4. Troubleshooting

Issue 1: 

Seed damage during filling

Solution:

Reduce auger speed to 60rpm

Activate vibration damping system

Issue 2: 

Nitrogen concentration fluctuation

Solution:

Check gas analyzer calibration

Replace membrane filters (every 500h)

Issue 3: 

Film static accumulation

Solution:

Ground all conductive components

Increase ionizer bar voltage to 7kV
