Kraft Paper Aluminum Foil Bags: Engineering Barrier Performance Through Advanced Liner Technology

The Oxygen Ingress Challenge: How 42% of Product Degradation Occurs Post-Packaging

In an era where 42% of product degradation happens after packaging (Packaging Digest 2024), Kraft Paper Aluminum Foil Bags have emerged as the critical solution for extended shelf life. At VidePak, we’ve engineered these systems to achieve 99.7% oxygen barrier performance while maintaining 98.3% recyclability through our proprietary 8-layer composite structure. Our 568-strong team, averaging 18 years of packaging engineering experience, operates at the material science frontier, creating hybrid solutions that exceed ASTM F1921 standards across 24 critical performance metrics.

Liner Technology Breakthroughs: The VidePak 8-Layer Composite System

1. Substrate Engineering

We begin with FSC-certified kraft paper (120-250gsm) as our structural foundation, combining it with 99.98% pure aluminum foil (7-12μ) through a patented vacuum deposition process. This hybrid substrate offers:

• Oxygen Barrier: <0.5 cc/m²/day (ASTM D3985)
• Light Blockage: 99.9% UV-Vis spectrum coverage
• Burst Resistance: 1,800-2,200 kPa (TAPPI T830)

Certifications:

• ISO 14001:2015 Environmental Management
• FSC-C154321 Chain of Custody

2. Barrier Technology Matrix

Our engineering team has developed three proprietary coating systems:

Liner System	Oxygen Permeability	Water Vapor Transmission	Cost Index	Recyclability
Alu 7μ	<0.5 cc/m²/day	<1 g/m²/day	9/10	★★☆
