Customer Success | How Matila CT-TL3 Elevates Film Tensile Strength and Versatility through 3-Layer Co-Extrusion
In the rapidly evolving flexible packaging industry, manufacturers are constantly seeking ways to balance cost-efficiency with high-performance film quality. The demand for thinner, stronger, and more transparent films has never been higher, particularly for lamination and high-end printing applications. This case study explores how L’Entreprise d'Emballage de Tunisie transformed its production capabilities by upgrading to the Matila CT-TL3 Three-Layer Co-Extrusion Blown Film Line.
The Strategic Advantage: Maximizing Strength and Material Versatility
For 3-layer machine users, the primary focus is often the tensile strength of the film and the flexibility to switch raw materials across different layers. Unlike traditional mono-layer machines, 3-layer co-extrusion technology offers a strategic approach to film composition:
- Enhanced Durability: By utilizing an ABC structure, manufacturers can strategically place specialized resins, such as a blend of LLDPE with Metallocene in the core layer (B), to achieve superior mechanical strength and puncture resistance.
- Material Optimization: The ability to alternate raw materials allows for a customized final product. For instance, high-clarity LDPE can be used in the outer layers (A and C) to enhance visual appeal, while cost-effective or high-strength resins are concentrated in the core.
- Product Diversification: This technological flexibility enables the production of a wide range of specialized products, from high-end lamination films to shrinkable packaging, tailored to specific client requirements.
Matila Die Head Design: Highlighting Final Product Characteristics
While many 3-layer machines exist, Matila’s unique die head design is specifically engineered to highlight the unique characteristics of the final product.
- Precision Distribution: Our die head ensures a more uniform distribution of materials across all three layers compared to standard industry designs. This eliminates common flow issues and ensures that each material’s properties are fully realized in the final film.
- Superior Gauge Control: Combined with a horizontal oscillating haul-off unit, this design keeps thickness deviations within a tight range of ±10%. This extreme precision ensures perfectly flat film reels, which are essential for high-speed printing and flawless lamination.
Comparative Results: The Transformation in Numbers
The transition to the Matila CT-TL3 delivered immediate and measurable improvements across all Key Performance Indicators (KPIs):
| Performance Metric | Previous Mono-Layer | Matila CT-TL3 (3-Layer) | Improvement |
|---|---|---|---|
| Average Output | 120 kg/hr | 180 kg/hr | +50% |
| Thickness Variation | ±12% | ±10% | Significant Stability |
| Tensile Strength | Standard | 20% Higher (at 15% less thickness) | Enhanced Durability |
| Haze (Clarity) | 12% - 15% | 8% - 9% | 30% Clearer |
| Energy Consumption | High (Belt-driven) | 15% Lower (Direct-driven) | Cost Reduction |
"Upgrading to Matila’s 3-layer machine was a smart move. Their unique die head design provides superior layer uniformity without the usual flow problems. Achieving a ±10% thickness tolerance via the horizontal oscillating haul-off has given us the perfect film quality for the further processing."
