4400mm High-Strength Corrugated Paper Machine

This article introduces a core piece of equipment designed specifically for the large-scale production of high-strength corrugated base paper—the 4400-type long-wire multi-cylinder paper machine. Its net paper width reaches 4400mm, with a working speed of 550 meters per minute and a maximum designed speed of 700 meters per minute. It is particularly suitable for producing various high-strength corrugated papers with a basis weight range of 90-160 g/m², producing only high-quality rolls, perfectly meeting the needs of downstream carton processing.

The machine’s outstanding performance, particularly its exceptional production efficiency, is its biggest highlight. Under typical production conditions of 120g/m² basis weight, this paper machine can achieve a stable production capacity of up to 418 tons/day, bringing substantial returns to investors. Precise control of technical parameters guarantees high quality: wire section dryness ≥22%, dryness entering the drying cylinder reaches 46-48%, and the final paper dryness is consistently around 92%. Simultaneously, superior cross-section control ensures that the cross-section moisture difference is ≤±1.0%, the cross-section basis weight difference is ≤±1.5%, and the cross-section shrinkage rate is controlled to an average of less than 4%, thus ensuring uniform physical properties across the entire roll and laying a solid foundation for manufacturing high-quality corrugated board.

Choosing our 4400 high-strength corrugated paper machine means choosing a reliable, efficient, and high-quality path to profitability. It’s not just a piece of equipment, but a strategic investment to enhance your market competitiveness and expand your market share. Whether you are planning to build a new production line or upgrade your technology, this optimized paper machine, combining efficiency and quality, is your ideal choice.
