2026 Blown Film Machine Trends: 5-Layer Co-Extrusion & Intelligent IBC Cooling Lead the Upgrade Wave

The global blown film machine industry is undergoing a profound technological transformation in 2026, driven by surging demand for high-barrier packaging, biodegradable films, and smart manufacturing. Multi-layer co-extrusion blown film machines, especially 5-layer and 7-layer models, have become the core growth engine, with market share increasing by 22% year-on-year.

In China, leading manufacturers such as Jinming Machinery have launched a new generation of 7-layer high-barrier blown film lines (M7B-9), equipped with IBC (Internal Bubble Cooling) system, 66-point precise temperature control, and European online thickness measurement system, controlling film thickness deviation within ±4%. Meanwhile, digital twin technology is rapidly applied: by building a multi-dimensional mirror of the screw extrusion system, abnormal condition identification time is shortened from 72 hours to 4.5 hours, and OEE (Overall Equipment Effectiveness) increases from 68% to 92%.

Industry data shows that the domestication rate of high-end blown film equipment in China will exceed 85% by 2028, driven by the "Made in China 2025" strategy and new energy efficiency standards (unit energy consumption reduced by 30%). For buyers, choosing a multi-layer co-extrusion blown film machine with IBC cooling and intelligent control has become the key to enhancing product competitiveness and reducing production costs.
