Product Introduction

The FFS tubular film machine for 25kg petrochemical granules represents cutting-edge packaging technology combining high-speed production (500-600 bags/hr) with precision weighing (±0.2% accuracy).  Utilizing triple-layer co-extruded PE/PP films (0.15-0.28mm thickness), this system integrates nitrogen flushing for oxidation-sensitive materials and ATEX-certified explosion-proof components for hazardous environments.  Its servo-driven forming collar creates seamless tubular bags with dual hot-bar sealing, achieving 30% higher efficiency than traditional woven bag packaging.

Operational Procedure

Film Loading

Mount 1.5m diameter film rolls on servo unwind shaft Thread through dancer rollers and forming tube

Parameter Setup

Input bag dimensions (standard 600×900mm) Configure loss-in-weight feeder parameters Set gas flushing flow rate (typically 5-8 L/min)

Production Cycle

Automatic tube formation → bottom seal Gravimetric filling with split-gate discharge Top sealing with batch coding Output via cleated conveyor (15m/min)

Maintenance Checklist

Daily:Clean residual particles from weigh hopper Check pneumatic filter moisture traps Inspect sealing jaw PTFE coatings

Monthly:

Replace worn film guide rollersLubricate chain drives with high-temp grease Calibrate load cells with test weights

Troubleshooting Guide

Issue: Film tearing during forming Solution: Adjust tension rollers and verify film thickness consistency Issue: Irregular seal strength Solution: Recalibrate temperature zones and check jaw parallelism Issue: Weighing fluctuations Solution: Clean load cell mounts and verify air cushion pressure

Frequently Asked Questions

Q1: What film properties suit abrasive petrochemicals? A: Minimum 150μm co-extruded film with nylon reinforcement layer

Q2: How does nitrogen flushing preserve material quality? A: Maintains<0.5% O2 concentration during filling via PID-controlled gas analyzer
