Woven Bags with PE Liners: Adaptability Through Co-Extrusion Film Innovation

When Barrier Performance Meets Custom Engineering: The VidePak PE Liner Advantage

Global supply chains face unprecedented challenges, with 68% of quality managers citing packaging failures as a top operational risk (Global Supply Chain Report, 2025). At VidePak, we’ve redefined woven bags with PE liners through our Modular Barrier System:

• Co-Extrusion Mastery: 9-layer films with 0.05mm-0.3mm thickness control
• Customization Depth: 12,400+ configuration combinations
• Quality Control: 0.68 defect rate per million bags (DPMO)

Our PE-Lined Woven Bags deliver measurable advantages across industries:

• 98% Fill Efficiency: Patented anti-bridging technologies
• 800N Burst Strength: For 1,200kg loads with 4:1 safety margins
• 8-Color Print Precision: Full-surface CMYK/Pantone matching

This approach achieves 99.7% defect-free production while maintaining 0.03mm thickness consistency—critical for clients like a Southeast Asian rice exporter that reduced spoilage by 87% through our AquaGuard™ system.

Customization Engineering: From Concept to Reality

Our PE liner solutions excel through four strategic pillars:

2.1 Co-Extrusion Capabilities

Layer	Function	Material	Thickness (μm)
1-3	Oxygen Barrier	EVOH/PVDC	8-15
4-7	Structural Integrity	LDPE/LLDPE	30-180
8-9	Heat Seal Integrity	mPE	10-25

Engineering Insight: Our Tri-Barrier™ Co-Extrusion achieves 99.2% oxygen block with 30% PCR content—23% more sustainable than virgin alternatives (SGS #CN2024-0723). This reduces rice spoilage by 87% in humid climates.

2.2 Customization Portfolio

• Valve Types: Open-mouth/spout/self-sealing (3-15cm diameters)
• Handles: Die-cut/woven/reinforced (50-300kg load ratings)
• Ventilation: Micro-perforations (0.5-3mm diameters)
• Shapes: Square/gusseted/conical (custom die plates available)
• Printing: 8-color process with 7+ lightfastness

Client Impact: A European pet food manufacturer reduced handling injuries by 78% through ergonomic die-cut handles with 150kg load ratings.

2.3 PE Liner Selection Guide

Type	Oxygen Barrier	Moisture Resistance	Cost	Ideal For

Operational Benchmark: Our AquaGuard™ mPE Liners achieve 98% moisture reduction with 0.05% oxygen transmission—industry-leading performance validated by SGS.

Technical Excellence: Engineering for Global Demands

Our 568-person team operates solar-powered facilities featuring:

• 102 Circular Looms: Weaving 1.2 million meters/month with ±2μm control
• 30 Lamination Lines: Dual-station PE/BOPP/Kraft systems
• 8 Printing Presses: Central impression flexo units with AI register control

Critical Equipment Allocation:

• Starlinger FIBC Lines: 0.7mm thickness consistency for 1,200kg loads
• W&H Extruders: BOPP film production with 98.7% uniformity
• Viscotec Recycling: Closed-loop systems reprocessing 1,200 tons/year

Performance Metric: 0.03mm thickness consistency across 1,200mm widths (ISO 16603)—critical for maintaining 800N burst strength in 1,200kg load applications.

Product Specifications: Industrial-Grade Engineering

Parameter	PE-Lined Bags	Test Method	VidePak Advantage
Material	PP/PE/Kraft Blends	ASTM D638	95% strength retention with 30% PCR
Thickness (μm)	50-300	ISO 4593	±2μm tolerance control
