In paper mills, wet end chemistry is a very important process and technology.
In addition to pulp ratio and fiber type, other additives also play an indispensable role.
The starches commonly used in the wet end are: cationic starch and amphoteric starch.
The type of starch to be used is usually determined by the wet end system, papermaking process, and the quality of the final product.
- Improve paper strength and stiffness
- Increase the thickness of the paper
- Improve pulp retention rate and dewatering efficiency
