Durable Robust Paper Bag Making Machine for Factories

Overview

With a 2500kg solid cast iron frame and reinforced components, it processes thick kraft paper (up to 300gsm) and multi-ply boards to produce durable shipping bags, industrial totes, and bulk packaging with exceptional longevity and minimal maintenance.

Features

Industrial-Grade Construction:

Vibration Resistance: Anti-vibration mounts reduce noise to <80dB and ensure stability at 180 BPM for multi-ply bags, maintaining ±0.3mm sealing accuracy.

Heavy-Duty Components: Tungsten carbide bearings (20,000-hour lifespan) and heat-treated steel gears (HRC 55) withstand harsh conditions ( -20°C to +50°C, 10–90% RH).

High-Capacity Processing:

Dual-Motor Drive: 15kW total power handles rolls up to 1500mm wide and 2000kg weight, with hydraulic roll loading for easy setup of heavy materials.

Thick-Blade Slitting: 8mm blades cut through 300gsm kraft and 5-ply corrugated board (7mm thickness), producing 99.5% straight edges (ISO 11562 compliant).

Low-Maintenance Design:

Self-Lubrication System: Automatic grease distribution every 2 hours, reducing manual maintenance to 2 hours/month, with sealed cabinets (IP54) protecting against dust/moisture.

Modular Wear Parts: Quick-release blade cartridges (30-minute replacement) and belt tensioners ensure minimal downtime in shift-based operations.

Safety Compliance:

Dual-Channel Safety: Emergency stop circuit with SIL 3-rated relays and protective enclosures, meeting ISO 13849 PLd standards for operator safety.

Application

Industrial Shipping: Produces large-format bags (up to 1200mm length) for machinery parts and construction materials, with automated palletizing integration (50 bags/pallet).

Agricultural Packaging: Creates grain/feed bags (100kg capacity) with UV-resistant coatings and fertilizer sacks with triple-layer seals (burst strength: 600kPa, FAO compliant).

Mining/Construction: Handles cement sacks (50kg) with airtight seals (5000N pressure) and sand bags with reinforced seams, tested to withstand 10m drops (ASTM D4169).
