Blown Film Machines: The Key to High-Quality Film Production

Blown film machines are vital for producing high-performance films with diverse characteristics, including barrier properties, strength variations, and aesthetic appeal. These films play a critical role across various industries such as food and dairy packaging, medical supplies, agriculture, and construction.

Modern blown film extrusion systems enable precise control of each layer’s thickness, composition, and function, ensuring superior mechanical strength, flexibility, and barrier performance. However, with numerous models available, choosing the right system can be a complex task.

That's why it's highly recommended to partner with an experienced manufacturer like Chyi Yang Industrial Co., Ltd. With over 60 years of industry expertise since 1965, Chyi Yang has earned a strong reputation for providing reliable, efficient, and innovative film extrusion solutions. Its machines are designed to be user-friendly, versatile, energy-efficient, and cost-effective, tailored to meet the evolving demands of global film production.

Smart Performance: 3-Layer Blown Film Machine

Chyi Yang’s flagship 3-layer blown film line is engineered for precision and productivity. Key innovations include:

> Segmented cooling ring with intelligent dual-airflow regulation, allowing real-time adjustment of film gauge, significantly reducing transverse thickness deviation.

> Closed-loop feedback software combined with ultra-responsive actuators, delivering exceptional gauge stability—crucial for applications with tight tolerance requirements.

> Internal Bubble Cooling (IBC) unit: Increases output by 10–15%, stabilizes bubble diameter, and minimizes edge trim—enhancing both efficiency and sustainability.

> High-precision Gravimetric Dosing System: Maintains recipe accuracy within ±0.1%, ensuring consistent weight-per-meter and excellent product repeatability.

> Ideal for: food & dairy packaging, greenhouse/agricultural films, shrink film & hood, construction sheets, liners, and heavy-duty sacks.

The Global Plastics Treaty was signed by 154 UN countries in Nairobi, Kenya on March 22, 2022, setting a target of using at least 30% recycled plastic in EU products and packaging by 2025 and reducing plastic by 60% by 2040.

Advancing Circular Economy: 5-Layer Co-Extrusion Film Blowing Machine

Chyi Yang’s 5-layer high-speed multi-layer co-extrusion system leads the industry in sustainable production:

Features automatic edge trimming and in-line granulation recycling, absorbing scrap directly into the innermost layer.

Eliminates the need for traditional edge trim crusher with refeeding system—waste is heated, extruded via a mini screw, cut, and air-cooled into reprocessable granules.

Equipped with an automatic regrind scaling system, enabling accurate weighing and formula calculation of recycled content during 24/7 continuous operation.

This intelligent recycling process ensures zero production waste, aligning with circular economy principles and ESG goals. As sustainability gains global momentum, Chyi Yang has become a preferred partner for environmentally conscious manufacturers seeking high-performance and eco-friendly blown film equipment.
