Our ABA PET Three-Layer Sheet Co-Extrusion Lines are designed for high-quality PET sheet production with a cost-efficient ABA structure. The line combines a high-performance parallel twin-screw extruder for the main layer with a single-screw extruder for the outer layer, producing stable, uniform and thermoforming-grade PET sheets.
We offer two main configurations:
• 75 Parallel Twin-Screw Extruder + 65 Single Extruder
• 85 Parallel Twin-Screw Extruder + 75 Single Extruder
The ABA co-extrusion structure allows manufacturers to optimize material distribution, improve production efficiency and reduce the consumption of higher-cost raw materials when suitable recycled or virgin PET materials are used.
Why Choose an ABA PET Sheet Co-Extrusion Line?
Cost-Efficient Three-Layer Structure
The ABA structure allows the A and B layers to use different PET material formulations according to the final application. This provides greater flexibility in balancing sheet performance and production cost.
Stable PET Extrusion
The parallel twin-screw extruder provides efficient plasticizing and mixing, helping achieve stable melt quality for continuous PET sheet production.
Suitable for Thermoforming
The produced PET sheets can be used for thermoforming applications such as food containers, fruit trays, clamshell packaging, bakery containers and other transparent packaging products.
Flexible Production Configuration
Two extruder combinations are available to match different production capacities, sheet widths, material requirements and investment levels.
Configurations
| Modèle | Matériaux | Structure de la vis | Screw Specification(mm) | Épaisseur de la feuille (mm) | Largeur de la feuille (mm) | Max. Extrusion Capacity (kg/h) |
| SWT-75S+65 | PET | Blocking Structure | φ75+65 | 0.15-2.0 | ≤1000 | 400-700 |
| SWT-85S+75 | PET | φ85+75 | 0.15-2.0 | ≤1000 | 600-1000 | |
| SWT-95+75 | PET | φ95+75 | 0.15-2.0 | ≤1000 | 1000-1500 |
The final configuration can be customized according to PET material, sheet width, sheet thickness, output requirement and end application.
ABA PET Sheet Production Process
PET Raw Material → Feeding & Drying → Parallel Twin-Screw Extrusion → Single-Screw Extrusion → ABA Co-Extrusion → T-Die → Three-Roller Calender → Sheet Cooling → Edge Trimming → Haul-Off → Cutting / Winding
The extrusion and calendering system is designed to maintain consistent sheet thickness, surface quality and dimensional stability during continuous production.
Applications of ABA PET Sheets
ABA PET sheets are widely used for manufacturing:
• PET food containers
• PET fruit and vegetable trays
• Bakery and cake containers
• Disposable food packaging
• Blister packaging
• Clamshell packaging
• PET thermoforming products
• Transparent packaging sheets
The line can be configured for different PET sheet specifications according to the customer’s thermoforming machine and finished-product requirements.
Key Advantages
High Material Flexibility
Different PET formulations can be assigned to different layers.
Efficient Material Utilization
The ABA structure can help optimize the use of virgin and recycled PET materials where the application permits.
Excellent Sheet Uniformity
Precise extrusion and calendering help maintain stable sheet thickness and surface quality.
Thermoforming Compatibility
Suitable for PET sheets used in vacuum and pressure thermoforming applications.
Scalable Production
Choose the 75/65 configuration for standard production or the 85/75 configuration for higher-capacity requirements.
Complete Production Line
Extrusion, co-extrusion, die, calendering, cooling, trimming and haul-off systems are integrated into one production solution.
How to Choose the Right ABA PET Sheet Extrusion Line?
Choose the 75 + 65 configuration when you need a compact and cost-effective solution for standard PET sheet production.
Choose the 85 + 75 configuration when higher production capacity, larger sheet width or greater processing flexibility is required.
Our engineers can recommend the appropriate configuration based on your target output, sheet thickness, sheet width, PET material and final thermoforming products.
Questions fréquemment posées
1. What is an ABA PET sheet co-extrusion line?
An ABA PET sheet co-extrusion line produces a three-layer PET sheet in which the outer layers use the same material structure while the core layer can use a different PET formulation.
2. What is the difference between 75 + 65 and 85 + 75?
The 85 + 75 configuration is designed for higher production requirements and larger processing capacity, while the 75 + 65 configuration provides a more economical solution for standard production.
3. Can ABA PET sheets be used for thermoforming?
Yes. ABA PET sheets can be designed for vacuum or pressure thermoforming applications, including food containers, trays and transparent packaging.
4. Can recycled PET be used?
The line can be configured for suitable recycled PET materials. The exact material ratio and processing conditions depend on the quality and properties of the recycled PET.
5. Can the PET sheet width and thickness be customized?
Yes. The die, calendering system and downstream equipment can be configured according to the required sheet width and thickness.
6. How do I choose the correct extruder configuration?
The selection depends mainly on required output, sheet width, thickness, PET material, recycled-material ratio and final application.
7. Can you provide a complete PET sheet production line?
Yes. A complete solution can include material handling, extrusion, ABA co-extrusion, T-die, calendering, cooling, edge trimming, haul-off and cutting or winding systems.
