4400mm High-Strength Corrugated Paper Machine
Our company offers a complete High-Strength Corrugated Paper Machine designed to meet the growing demand for quality packaging paper. This paper mill equipment is a full paper production line that turns waste paper pulp into high-strength corrugated paper, linerboard, and T paper. The High-Strength Corrugated Paper Machine uses two air-cushion headboxes or hydraulic headboxes, depending on your final choice. The forming section of this High-Strength Corrugated Paper Machine uses a two-ply wire design, which helps build a strong and uniform sheet. The press section features a vacuum pick-up and a four-roll three-nip composite press with hydraulic loading, cantilever felt changing, and a hydraulic system with accumulators. This High-Strength Corrugated Paper Machine also includes a multi-point small gear closed gearbox drive for the drying section, a closed hood, oil lubrication, a paper threading system, and a reeling machine with a paper rack. When you choose our High-Strength Corrugated Paper Machine, you get a reliable paper manufacturing machine that delivers consistent quality and high output for your paper mill.

The process flow of our High-Strength Corrugated Paper Machine is designed for efficiency and strength. The waste paper pulp is prepared and fed to the headbox at the right consistency. The two-ply wire forming section creates a strong base sheet, and the vacuum pick-up transfers it smoothly to the press section. The four-roll three-nip composite press removes water effectively and builds sheet density. The drying section uses a multi-point gear drive and a closed hood for even drying. The paper threading system helps guide the sheet through the machine, and the reeling machine winds it into neat rolls. Our High-Strength Corrugated Paper Machine also meets strict utility requirements. It uses low voltage and high voltage power, clean water with specific quality standards, compressed air with filtration, and saturated steam at the required pressure.
Beyond our High-Strength Corrugated Paper Machine, we offer complete solutions for other paper grades. We can supply paper production lines for cultural paper, newsprint, writing paper, and specialty papers. Our range of paper mill machinery includes pulpers, refiners, screens, cleaners, headboxes, forming sections, press sections, drying sections, calenders, and reeling machines. We also provide turnkey paper production line services, from design to installation.
