What are the benefits of the 7/9/11 layer blown film extrusion line over the 3/5 layer?


At PLASTAR, we understand the importance of high-quality blown film extrusion lines for various industries. That is why we offer state-of-the-art 7, 9, and 11-layer blown film extrusion lines that provide numerous benefits over the traditional 3-layer line and 5-layer line. In this article, we will explore the benefits of using advanced blown film extrusion lines and how they can enhance your business operations.

Improved Film Quality

The 7, 9, and 11-layer blown film extrusion lines are designed to produce films with superior quality compared to 3 and 5-layer lines. The 7, 9, and 11-layer lines produce films with improved mechanical strength, better barrier properties, and increased puncture resistance. These features are particularly useful for packaging applications where the film must protect the contents from environmental factors.

Enhanced Production Efficiency

Another advantage of the 7, 9, and 11-layer blown film extrusion lines is their ability to increase production efficiency. It can produce films at higher speeds, resulting in a significant reduction in production time and costs. Additionally, it can produce films with uniform thickness, reducing the need for costly quality control measures.

Increased Customizability

The 7, 9, and 11-layer blown film extrusion lines offer greater flexibility in terms of customizability. It can produce films with varying thicknesses, widths, and colors to meet your specific requirements. This level of customizability is particularly useful for industries with unique packaging requirements.

Better Sustainability

Sustainability is a key concern for many industries, and the 7, 9, and 11-layer blown film extrusion lines can help you reduce your environmental footprint. It produces films with thinner gauges, resulting in reduced material usage and waste. Additionally, the 7, 9, and 11-layer lines use less energy, reducing your carbon footprint and operating costs.


In conclusion, the 7, 9, and 11-layer blown film extrusion lines offer numerous benefits over traditional 3 and 5-layer lines. These 7, 9, and 11-layer lines produce films with superior quality, enhanced production efficiency, increased customizability, and better sustainability. By investing in advanced blown film extrusion lines, you can significantly enhance your business operations and gain a competitive edge in your industry.
