59 Layers CoExtrusion WaterCooled Blown Film Machine China Suppliers Factory
The 5-9 Layers Co-Extrusion Water-Cooled Blown Film Machine represents the pinnacle of plastic extrusion technology, specifically engineered for the production of high-performance composite films. By integrating advanced multi-layer co-extrusion with a precision water-cooling system, this machine allows for the seamless combination of diverse resin materials—such as PE, PP, PA, and EVOH—to create films with superior barrier properties, enhanced mechanical strength, and exceptional chemical resistance.
Designed for versatility and efficiency, this system utilizes a specialized down-blowing process and a high-thermal-conductivity water-cooling jacket. This configuration is ideal for manufacturing thick, rigid industrial packaging as well as high-clarity pharmaceutical and food-grade films, effectively eliminating high-temperature degradation and ensuring maximum gloss and stability in every roll.

Frequently Asked Questions
Q: What is the primary advantage of water-cooling over air-cooling in blown film machines?
Water has much higher thermal conductivity than air, allowing for rapid cooling of the film bubble. This prevents high-temperature degradation of the resin, enhances film transparency, and increases overall production efficiency.
Q: Which materials can be processed by the 5-9 layer co-extrusion system?
The system is compatible with a wide range of resins including Polyethylene (PE), Polypropylene (PP), Polyamide (PA), and Ethylene Vinyl Alcohol (EVOH) to create high-barrier composite films.
Q: Why is the "down-blowing" process preferred for industrial packaging?
Down-blowing uses gravity to assist in pulling the film, which significantly reduces bubble sway. This makes it ideal for producing thicker, more rigid films required for industrial applications.
Q: What applications are best suited for multi-layer composite films?
These films are essential for food and pharmaceutical packaging (where oxygen/moisture barriers are critical), agricultural films, and high-strength industrial protective films.
Q: How does the number of layers (5-9) affect the final product?
More layers allow for a more complex "sandwich" structure (e.g., ABABC), enabling the combination of a strong outer layer, a high-barrier inner layer, and a sealant layer for optimal packaging performance.
Q: Does the water-cooled system improve the gloss of the film?
Yes, by rapidly quenching the melt and preventing uneven cooling or degradation, the water-cooling system significantly improves the surface gloss and optical clarity of the finished film.
