Packaging paper high consistency refining:
For treating waste paper pulp, the high consistency refining system can significantly increase burst strength and folding endurance, and enhance internal bonding strength. Packaging paper uses recycled waste paper as raw
material has problems of difficult to guarantee the strength performance
indicators including folding resistance, burst resistance, ring pressure, etc.
In large-scale production, it is necessary to add higher-priced high-quality
fibers and reinforced chemical materials. To ensure the required strength of
the paper, the cost increases and the water treatment system is more difficult
to deal with. The high-consistency refining system provided by Genda can solve
this problem. We have cooperated with many customers and have completed the
construction and renovation of more than 30 production lines. Our solution
covers various needs of customers: innovative technology, reliability and
operability, advanced automation solutions and general contract engineering
services, to ensure our client improve paper performance and reduce operating
costs while maintaining smooth operation.
