Double Sided Knitted Fabric Laminated Eva

Double sided knitted fabric laminated EVA shipped to North America

Case Study: High-Density EVA Laminate Slashes Material Waste for Premium Luggage Manufacturer

How a 4-Prototype Optimization Cycle Delivered 15% Cost Savings

Client: Top-Tier Luggage Brand

Application: Protective Interior Linings for Luxury Travel Cases

Material: Double-Sided Knit Fabric Laminated with Custom EVA Foam

The Challenge

Our client faced two critical issues in their high-volume production:

1. Material Inefficiency: 22% EVA shrinkage causing pattern waste
2. Performance Gaps:
- Weak corner impact protection
- Inconsistent adhesive bonding in extreme temperatures

Our Solution: Precision-Engineered EVA Laminate

+ Water-Based Eco-Adhesive System
+ High-Density EVA Core (0.55g/cm³)
+ Double-Sided Knit Reinforcement

Key Technical Advantages:

- ✦ Zero Permeability: Complete moisture/oil barrier (0g/24hr MVTR)
- ✦ Shock Absorption: 85% energy dissipation (EN 1621-1 Standard)
- ✦ Waste-Reduced Cutting: ±0.8% dimensional stability after lamination

Optimization Journey: 4-Stage Breakthrough

1. Prototype V1
- Baseline EVA formulation
- Client Feedback: 18% material waste during die-cutting

2. Prototype V2
- Modified EVA cross-linking density
- Added anti-shrink stabilizers
- Result: Waste reduced to 12%

3. Prototype V3
- Precision-calibrated lamination tension
- Edge-sealing treatment
- Result: 7% waste + passed -40°C cold crack test

4. Prototype V4
- Oil-resistant topcoat
- Optimized roll widths for client’s patterns
- Final Waste Rate: 5.3%
