The Blueprint of Durability: How Multiwall Bags Protect Your Products
Multiwall paper bags represent the evolution of industrial packaging, combining multiple kraft layers with advanced barrier technologies. Modern designs feature:
- Precision Valves: 0.5mm tolerance filling ports with anti-clog geometry
- Ventilation Matrix: 200µm laser-drilled micro-perforations for respiration control
- Bio-Barrier Coatings: 98% plasticizer-free water-based formulations
VidePak’s manufacturing ecosystem includes:
- 8 W&H WSB 1200 Machines: Producing 1.2M bags/month at 99.2% OEE
- 16 Starlinger RV 13i Extruders: Applying 40µm LDPE liners at 150m/min
- 12 Gallus Flexo Presses: 8-color HD printing with 97% PANTONE® match
Certification Portfolio:
- ISO 11607-1:2019: Package integrity validation for medical devices
- FSC-C156789: Sustainable sourcing chain-of-custody certification
- ASTM D6868-24: Compostable coating formulations
Parameter Masterclass: Matching Specs to Real-World Needs
Selecting optimal bag parameters requires balancing product characteristics with supply chain realities:
Thickness Spectrum (80-300μm)
- 80-120μm: Light powders (flour, milk replacer)
- 150-200μm: Granular materials (fertilizer, animal feed)
- 250-300μm: Abrasive substances (industrial chemicals)
Engineer’s Note: “We specify 180μm for coffee – thick enough for stacking yet flexible enough for palletizing.”
Grammage Guide (60-200gsm)
- 60-80gsm: Retail spices, pharmaceuticals
- 100-140gsm: Industrial bulk packaging
- 160-200gsm: Hazardous materials (UN Y22 certified)
Logistics Hack: “Our 70x100cm bags optimize EU pallets (120x80cm) with 92% cube utilization.”
Sizing Matrix (30x40cm to 90x120cm)
- Small (30x40cm): Retail spices, pharmaceuticals
- Medium (50x80cm): Food ingredients, construction chemicals
- Large (90x120cm): Bulk powders, pet food
