5 Layer CoExtrusion Blown Film Machine Factory Suppliers in China
The 5-Layer Co-Extrusion Pro Blown Film Machine is a high-performance industrial solution engineered for the production of premium multi-layer films. Whether you require non-barrier laminated films for superior flexibility and tensile strength or high-barrier films for oxygen and moisture protection, this system delivers unparalleled precision. It is specifically designed to optimize the extrusion process, ensuring stable fusion of diverse PE materials and high-barrier resins like EVOH and PA.
By leveraging advanced die design and precise flow channel control, the machine prevents interlayer defects such as delamination and inclusions. This results in a high-quality composite structure that significantly extends the shelf life of packaged products while maintaining excellent mechanical strength and chemical stability, making it an ideal choice for the most demanding soft packaging applications.

Frequently Asked Questions
Q: What is the difference between barrier and non-barrier 5-layer films?
Non-barrier films focus on flexibility and strength using PE materials. Barrier films incorporate materials like EVOH or PA to block oxygen and moisture, extending the shelf life of the packaged product.
Q: How does the machine ensure uniform layer thickness?
The machine uses a precision-engineered die with a carefully designed flow channel that controls the flow rate and pressure of each layer independently.
Q: Which raw materials are compatible with this blown film line?
It is compatible with a wide range of resins including HDPE, LDPE, LLDPE, EVA, and MLLDPE, as well as barrier resins like EVOH and PA.
Q: Can the output be customized for specific production targets?
Yes, the output is adjustable based on the chosen model, film width, thickness, and the characteristics of the raw materials used.
Q: What prevents delamination in the multi-layer structure?
Delamination is prevented by precise rheological control of the melts, ensuring stable fusion of materials with varying viscosities and processing temperatures.
Q: What is the typical application for the 5-layer ABC structure?
The ABC structure is typically used for high-performance packaging where different properties (e.g., outer gloss, inner sealability, and middle strength) are required in a single film.
