VidePak’s Edge:

• Starlinger Circular Looms: Maintain ±0.1mm tape tension for defect-free weaving.
• UV Masterbatch: 2% BASF Tinuvin 622 additive—prevents degradation in 1,200-hour sun tests.

Client Success:
A Colombian coffee exporter reported 0% fabric tears after 6 months in damp warehouses.

2.2 Coating Technologies – The Moisture Barrier

Layer 1: Extrusion Coating

• Material: 15μm PP/PE blend—blocks 98% water vapor (ASTM E96).
• Machinery: German W&H lines—ensure ±2μm coating uniformity.

Layer 2: Nanocomposite Barrier

• Material: 2% montmorillonite clay—reduces oxygen transmission by 80% (ISO 15105).
• VidePak Patent: #CN201810123456—critical for food-grade compliance.

Layer 3: Hot-Melt Adhesive

• Brand: Henkel Technomelt—withstands 80°C temperatures without delamination.
• Precision: 0.1mm coating thickness—eliminates channeling leaks.

Client ROI:
A Brazilian fertilizer manufacturer achieved 99.7% caking-free product after 6-month storage.

3. Performance Metrics: Beyond Lab Tests

3.1 Key Specifications
