Advanced blown film technology for improved operational efficiency and sustainability

With over five decades of experience, Kung Hsing Plastics Machinery has become a prominent player in the field of plastic extrusion. Over the years, the company has developed an extensive range of machinery, including blown film lines, monofilament-making machines, and plastic recycling machines. These innovations have helped Kung Hsing Plastic Machinery maintain its competitive edge in a rapidly evolving industry. As a trusted name in extrusion technology from Taiwan, Kung Hsing Plastic Machinery responds to evolving packaging manufacturing industry in various parts of the world by offering highly efficient blown film technologies to ensure growth and sustainability.

International Plastics News for Asia had the chance to discuss with Mr. Kun Lin Tsai, Vice President of Kung Hsing Plastic Machinery, on the company technology development goals and how these have been helping their target markets achieve sustainable production.

Mr. Kun Lin Tsai, Vice President, Kung Hsing Plastic Machinery

Kung Hsing Plastic Machinery has been in the forefront of blown film technology development. What are the trends that have been encouraging the company’s innovations in this field?

Mr. Kun Lin Tsai: Kung Hsing Plastic Machinery’s innovation in blown film technology has been driven by a convergence of long-term industry trends rather than short-term market demands. Key among these trends is the growing need for process stability in multi-layer structures, increasing pressure for material reduction (downgauging), and the rapid rise of sustainability and circular economy requirements, particularly in packaging.

At the same time, packaging manufacturers are facing more complex production realities—shorter runs, diversified product structures, and greater dependence on consistent quality rather than maximum output alone. These challenges have encouraged the commpany to focus its development efforts on engineering robustness, system integration, and long-term production reliability, ensuring that advanced blown film technologies perform consistently under real factory conditions.

What are the key features of Kung Hsing Plastic Machinery’s multilayer co-extrusion high-speed blown film system that has made it highly competitive and ideal for today's packaging sector?  

Mr. Kun Lin Tsai: Kung Hsing Plastic Machinery’s multilayer co-extrusion high-speed blown film systems are designed around a total-system engineering concept, rather than isolated machine performance. Several features contribute to their competitiveness in today’s packaging sector. One is high process stability at elevated speeds, supported by rigid mechanical structures and optimized thermal balance, ensuring stable bubble behavior and consistent film quality. Another feature is the precise melt distribution and layer control, enabling uniform gauge profiles and reliable multi-layer structures essential for lamination films and high-barrier food packaging. Also, advanced thickness control systems support downgauging strategies while maintaining stable film performance and production yield. In addition to these features, flexible system configurations allow converters to adapt layer structures, materials, and recipes to evolving packaging requirements without compromising efficiency.

Together, these features make Kung Hsing Plastic Machinery’s systems particularly suitable for converters seeking high productivity combined with consistent quality and long-term operational reliability.

Are there any value-added features that have been installed to the company’s high-speed blown film system lately? What are these and what will be their benefits to your customers?

Mr. Kun Lin Tsai: In recent developments, Kung Hsing Plastic Machinery has placed strong emphasis on value-added features that improve usability, sustainability readiness, and operational efficiency. These include: enhanced digital monitoring and data feedback capabilities, allowing operators and plant managers to better understand process behavior and optimize production conditions; improved user-oriented control interfaces and recipe management, which reduce operator dependency and shorten learning curves in increasingly complex multi-layer operations; design refinements that enhance compatibility with PCR and alternative materials, supporting customers’ sustainability and regulatory objectives.

The benefits for customers are tangible: faster stabilization after changeovers, more predictable production outcomes, reduced material waste, and improved alignment with sustainability targets—all contributing to stronger long-term ROI.

Blown film technology from Kung Hsing Plastic Machinery responds to the challenges being faced by packaging manufacturers.

Kung Hsing Plastic Machinery has been able to penetrate the international markets, and achieve successful market expansion. This has been challenging. In China, for example, what made your products stand out?

Mr. Kun Lin Tsai: In highly competitive markets such as China, our products have stood out primarily due to our reliability, engineering depth, and consistency in real production environments. While many suppliers compete on initial cost or headline specifications, our customers increasingly recognise the value of stable long-term operation, especially for multi-layer and high-speed applications.

Kung Hsing Plastic Machinery’s experience in delivering systems capable of handling complex structures, downgauging requirements, and demanding quality standards has resonated strongly with converters serving food, industrial, and specialty packaging markets worldwide.

Looking ahead, Kung Hsing Plastic Machinery continues to see growth opportunities in America, Europe, Southeast Asia, the Middle East, and selected emerging markets, where sustainability regulations, packaging sophistication, and demand for high-performance blown film solutions are accelerating.

What are the future plans of Kung Hsing Plastic Machinery as far as product development is concerned? Are you developing new products

Mr. Kun Lin Tsai: Kung Hsing Plastic Machinery’s future product development strategy is focused on evolution rather than disruption. Rather than launching entirely new machine concepts, the company is investing in continuous advancement of its core blown film platforms.

Key development directions include: further enhancement of multi-layer system stability and control, particularly for higher layer counts and complex material combinations; expanded sustainability-oriented capabilities, including improved processing of recycled and alternative materials; and deeper integration of digital tools and data-driven process optimization, supporting smarter manufacturing environments.

These developments reflect Kung Hsing Plastic Machinery’s long-term commitment to providing not just machines, but reliable production platforms that can adapt to changing materials, regulations, and market demands over the full lifecycle of the equipment
