Processes Natural Fibers for Packaging Solutions
The NATUREPREP KFP from Kiefel is a comprehensive fiber preparation system, designed to process natural fibers into high-quality packaging solutions. This system utilizes a series of procedures, including pulping, deflaking, refining, pressure screening, and additive mixing, to efficiently transform inputs into ready-to-form pulp. With batch and continuous operational modes, it caters to varying production scales — from small batch operations to large-scale continuous outputs. Capable of processing up to 250 kg of virgin or recycled fiber per hour, the NATUREPREP KFP supports industries ranging from agriculture to high-tech sectors, producing robust end products like egg cartons, fruit trays, and electronic device packaging. Its modular design allows for easy integration into existing production lines and swift reconfiguration to meet changing market demands. Designed with energy efficiency in mind, it ensures minimal waste and optimal resource use. The system’s robust steel construction ensures durability and resistance to corrosion, aligning with industry standards for safety and operational efficiency.
