Product Description


Twin-screw processing and production systems, developed by Clextral for over 30 years, enable paper-industry manufacturers to produce high-quality cellulose pulp economically and ecologically. Clextral systems are designed to reduce pulp production costs and environmental impact, featuring low-chemical pulp processing and minimum water consumption.

Specific products, such as writing paper, cardboard and banknote paper can be made using a wide variety of raw materials, including softwood and hardwood, textile fibers, annual plants, agricultural waste products and recycled fibers.

Practical information

Linen fiberTwin-screw Bivis pulping is based on the use of a co-rotating twin screw at the heart of the system. The primary advantage of this system is its ability to process very long cellulosic fibers and fiber bundles to produce pulp with controlled fiber lengths and distribution features.

Clextral systems ensure fiber defibering, chemical impregnation, washing and bleaching to obtain custom-designed pulp to produce papers for a wide variety of applications, from high-quality banknotes to bulk cardboard, via special writing papers and molded fibers .technology.

A wide selection of raw materials can be used, including:
