Stock preparation solutions for molded fiber production

Ensuring end-product quality

Achieving high-quality molded fiber products starts with an optimized stock preparation process. Valmet's solutions, typically including pulping, followed by protection screening and refining are designed to help molded fiber manufacturers produce consistent, high-quality products while ensuring smooth, efficient operations.

Consistent product quality

Operational efficiency

Maximized fiber utilization

In an automated process, pulp bales are loaded, de-stacked and de-wired on conveyor, feeding the pulper with correct fiber types. Valmet´s advanced pulper technology efficiently separates the fibers for further treatment. Our protection screens then remove large contaminants, safeguarding downstream equipment and preventing costly downtime.

In the next phase, Valmet’s leading, energy-efficient refining technology enhances fiber bonding and consistency, ensuring the preferred qualities and strength in the final molded fiber products—whether for protective packaging, food containers, or consumer goods.

Benefits of microfibrillated cellulose (MFC)

Did you know that microfibrillated cellulose (MFC) can increase the end-product quality also in molded fiber production? MFC produces a wide range of benefits including increased tensile strength, improved barrier properties, smoother surfaces, and more. Valmet has pioneered a unique, refiner-based technology for MFC production. The production process combines advanced refiner and filling technology with an innovative control system designed to maximize production efficiency.
