Moisture Barrier Paper — Export packaging

Description

1. Product Overview

This is a multi-layer, kraft-based moisture barrier paper designed to protect metal goods, machinery, and sensitive components from humidity-induced damage during export transit. Its primary industrial use is as a VCI (Vapor Corrosion Inhibitor)-compatible wrapping or interleaving material for ocean freight and high-humidity仓储. The key value proposition is a 99%+ relative humidity blockage rate combined with tear resistance, eliminating the need for expensive plastic laminates in many applications. Strategically, it reduces product rejection rates and warranty claims, making it critical for just-in-time global supply chains.

2. Key Specifications & Technical Characteristics

• Chemical composition: Three-layer co-extruded kraft paper with polyethylene (PE) coating and optional VCI coating; fiber sourced from FSC-certified pulp

• Purity/grade: Industrial grade ASTM D-882 compliant; water vapor transmission rate (WVTR) ≤ 5 g/m²/24h at 38°C / 90% RH

• Physical characteristics: Natural brown or white; basis weight 60–120 gsm; tensile strength MD ≥ 6 kN/m; smooth one-side coating; perforation-free

• Packaging options: Jumbo rolls (width 500–2,500 mm; core 3″ or 6″); slit rolls; custom sheets; anti-dust shrink-wrapped

• Shelf life: 24 months in original packaging (20–25°C, <70% RH)

3. Core Industrial Applications

• Primary industries: Automotive parts export, heavy machinery, steel coils, aerospace components, electronics, and military logistics

• Specific use cases: Wrapping engine blocks for sea freight; lining shipping crates for bearings; interleaving stamped metal sheets; covering palletized transformers

• Performance advantage: Outperforms standard kraft or VCI poly films by combining mechanical puncture resistance (no stretching or cling) with high moisture holdout; no adhesive residue; recyclable as paper stream, lowering disposal costs

• Efficiency gain: Reduces desiccant usage by up to 60% in container packaging; enables 24-hour longer open-time during cargo assembly vs. standard paper

4. Competitive Advantages

• Quality consistency: ISO 9001:2025-certified production with inline WVTR testing; batch traceability via QR code

• Supply reliability: Dual manufacturing sites (Asia & Europe); 98.5% on-time-in-full rate over 18 months

• Logistics capability: Pre-slit to customer width; ready for just-in-sequence delivery to packing lines

• Price competitiveness: 12–18% lower total applied cost than premium PE/aluminum laminates on a per-pallet-wrapped basis

• Sustainability: 100% recyclable in standard paper streams; carbon-neutral shipping available; meets EU packaging directive 94/62/EC

• Technical support: Free humidity risk audit for new accounts; custom VCI loading based on cargo metal type

5. Commercial & Supply Information

• Minimum order quantity (MOQ): 5 metric tons (mixed widths allowed)

• BULK loading capacity per 20FT container: 20 metric tons (approx. 180–220 jumbo rolls depending on gsm and width)
