FAQ

1. What is the advantage of 3-layer coextrusion compared to single-layer film production?
3-layer coextrusion allows for material combination, where each layer can serve different functions - strength, sealing, or barrier properties - resulting in higher quality films with reduced material costs.

2. Can this machine produce biodegradable films?
Yes, the machine can process various biodegradable materials when properly configured, though material compatibility should be verified based on your specific requirements.

3. What types of products can be made with the produced films?
The films are suitable for packaging bags, shopping bags, garment bags, agricultural films, and protective covers.

4. How is the film thickness controlled?
The machine features automatic thickness control system with ultrasonic measurement and automatic die adjustment to ensure consistent film thickness.

5. What support do you provide after purchase?
We offer installation guidance, operational training, technical support, and supply genuine spare parts with responsive after-sales service.
